On July 21, 2010, a settlement
agreement was approved by the Court
(CV–10–357, D. D.C.) in which the
Service agreed to submit to the Federal
Register by July 29, 2011; September 30,

four of the petitioned species. On
August 9, 2011, the Service published in
the Federal Register a 12-month status
review and proposed rule for the
following four parrot species: Crimson
shining parrot, Philippine cockatoo,
white cockatoo, and yellow-crested
cockatoo (76 FR 49202).
Current Action
In this status review, we make a
determination whether the petitioned
action is warranted, not warranted, or

actions for the blue-headed macaw and
grey-cheeked parakeet. This Federal
Register document complies, in part,
with the second deadline in the courtapproved settlement agreement
mentioned above.
Species Information and Factors
Affecting the Species
Section 4 of the Act (16 U.S.C. 1533)
and implementing regulations (50 CFR
part 424) set forth procedures for adding
species to, removing species from, or
reclassifying species on the Federal
Lists of Endangered and Threatened
Wildlife and Plants. Under section
4(a)(1) of the Act, a species may be
determined to be endangered or
threatened based on any of the
following five factors:
(A) The present or threatened
destruction, modification, or
curtailment of its habitat or range;
(B) Overutilization for commercial,
recreational, scientific, or educational
purposes;
(C) Disease or predation;
(D) The inadequacy of existing
regulatory mechanisms; or
(E) Other natural or manmade factors
affecting its continued existence.
In considering whether a species may
warrant listing under any of the five
factors, we look beyond the species’
exposure to a potential threat or
aggregation of threats under any of the
factors, and evaluate whether the
species responds to those potential
threats in a way that causes actual
E:\FR\FM\12OCP5.SGM
12OCP5
Federal Register / Vol. 76, No. 197 / Wednesday, October 12, 2011 / Proposed Rules
impact to the species. The identification
of threats that might impact a species
negatively may not be sufficient to
compel a finding that the species
warrants listing. The information must
include evidence indicating that the
threats are operative and, either singly
or in aggregation, affect the status of the
species. Threats are significant if they
drive, or contribute to, the risk of
extinction of the species, such that the
species warrants listing as endangered
or threatened, as those terms are defined
in the Act.
Below is a species-by-species
description and analysis of the five
factors. The species are considered in
alphabetical order, beginning with the

I. Blue-Headed Macaw (Primolius
couloni)
Species Description
The blue-headed macaw is a small
species of macaw belonging to the
family Psittacidae, the parrot family. It
measures approximately 41 centimeters
(cm) (16 inches (in)) in length. Average
male and female wing length measures
approximately 226 millimeters (mm)
(8.9 in) and 220 mm (8.6 in),
respectively. Average tail lengths for
males and females measure 223 mm (8.7
in) and 204 mm (8.0 in), respectively
(Forshaw 1973, p. 386). There is little
sexual dimorphism between males and
females (Lee 2010, p. 5). Adults are
characterized by green general plumage
with slightly more yellowish
underparts. The entire head, except for
the grey bare facial area, is blue.
Primaries and primary-coverts (wing
feathers) are blue and secondaries and
outermost upper wing-coverts are blue
edged with green. The upperside of the
tail is blue, whereas the undersides of
flight and tail feathers are a dusky
yellow. The bill is grey-black, which
becomes horn-colored on the culmen
(the upper ridge of the bill) and at the
tip of the upper mandible. The iris is
yellow, and legs are flesh-pink.
Immature blue-headed macaws have not
been described (Forshaw 1973, p. 386).
The blue-headed macaw occurs
mainly in eastern Peru, in the
´
departments of Loreto, Huanuco, Pasco,
Ucayali, Cusco, Madre de Dios,
´
Ayacucho, Puno, and Junın; but it also
occurs just inside the border of extreme
western Brazil, in the States of Acre and
ˆ
Rondonia, and just inside the border of
northern Bolivia, in the departments
Pando, Beni, and La Paz (BirdLife
International (BLI) 2011a, unpaginated;
Tobias and Brightsmith 2007b, pp. 1–6).
It has been recorded from 61 localities,
VerDate Mar<15>2010
19:14 Oct 11, 2011
Jkt 226001
with no significant association with
forest type, riverine habitats, degree of
disturbance, or altitude. Records of the
blue-headed macaw occur in both
foothill regions and lowlands ranging in
elevation from 200 meters (m) (656 feet
(ft)) to 1,500 m (4,921 ft), and in a wide
range of habitats, including terra firme
forests (forests not inundated by flood
waters), mature floodplain forests,
successional river edge forests, and
Mauritia palm swamps. One study
found that this species was slightly
more common in degraded areas than in
pristine forests (Brightsmith 2009,
personal communication (pers. comm.);
Tobias and Brightsmith 2007, pp. 126,
129–130).
The estimated total global range for
this species is 609,494 square kilometers
(km2) (235,326 square miles (mi2)) and
spans large areas of remote and
unexplored terrain. The extent of
occurrence (the global range, excluding
disjunctions and major areas of
inappropriate habitat) has been
calculated as 460,000 km2 (177,606
mi2), an area larger than previously
thought (Brightsmith 2009, pers. comm.;
Tobias and Brightsmith 2007, pp. 126,
129, 133). However, the extent of
occurrence may be underestimated, as
data is lacking from Brazil, the global
range is more than 90 percent forested,
and data suggest anthropogenic
pressures have not eliminated this
species from any large areas (Tobias and
Brightsmith 2007, p. 129). Brightsmith
(2009, pers. comm.) notes that the blueheaded macaw is not absent from any
portion of its historical range.
In 1990, Lambert et al. (2003, as cited
in Tobias and Brightsmith 2007, p. 127)
estimated the global population of blueheaded macaws to be 10,000
individuals. In 2003, Gilardi estimated
the global population to be well under
1,000 mature individuals; BLI revised
the global estimate to 1,000–2,499
mature individuals in 2005 (Tobias and
Brightsmith 2007, p. 127). It is unclear
why population estimates have varied,
but may be due to few published
sources, anecdotal accounts, poor data
quality (Tobias and Brightsmith 2007, p.
127), or differences in methodology. The
most recent data suggest that this
species occurs at a conservative density
of one mature individual per 10–50 km2
(3.0–19.3 mi2); using the calculated
460,000 km2 extent of occurrence,
Tobias and Brightsmith (2007, p. 126)
estimate the population to be 9,200–
46,000 mature individuals and 11,500–
57,500 individuals if immature birds are
included (Tobias and Brightsmith 2007,
p. 133). Most of the 61 localities where
this species has been recorded are easily
accessible by road or river, potentially
PO 00000

Fmt 4701

causing a bias towards areas affected by
trapping and underestimating
abundance. Furthermore, much of the
global range has yet to be surveyed
(Tobias and Brightsmith 2007, pp. 132–
133).
BLI (2011a, unpaginated), based on
Tobias and Brightsmith (2007, pp. 126–
138), reports that the population is
declining at a slow-to-moderate and
ongoing pace. However, Brightsmith
(2009, pers. comm.) notes that this
conclusion is not based on real evidence
from wild populations. In fact, Tobias
and Brightsmith (2007, p. 134) and
Brightsmith (2009, pers. comm.) note
that based on sightings data, there is no
evidence of a decline in range or
numbers of blue-headed macaws in the
wild and that the possibility that the
blue-headed macaw is increasing with
the spread of degraded forests along
rivers cannot be discounted (Tobias and
Brightsmith 2007, pp. 132–133).
Hennessey (2011, per. comm.) also notes
that populations in Peru and Bolivia
have remained healthy. There is no
place within its range where this species
has been searched intensively and does
not occur (Brightsmith 2009, pers.
comm.). At the Tambopata Research
Center, blue-headed macaws have been
steadily increasing since the year 2000
(Brightsmith 2009, pers. comm.).
Sightings of the blue-headed macaw in
Peru have also increased in the past 10
years (Brightsmith 2009, pers. comm.).
Additionally, the lowlands of
southeastern Peru, the core of the
species’ range, are the home of a wide
variety of international research
stations; parrot populations are
monitored annually, so if the blueheaded macaw begins to decline, the
research community would note this
and begin specific protection and
recovery actions (Brightsmith 2009,
pers. comm.).
The diet of the blue-headed macaw
has not been observed; however, parrots
generally feed on seeds, ripe and unripe
fruit, and flowers, but may also utilize
other plant parts, such as nectar, leaves,
and bark (Lee 2010, p. 6; Brightsmith
2006, p. 2; Cowen no date (n.d.), pp. 5,
17). Cowen (n.d., p. 16) found that a
psittacine community, which included
the blue-headed macaw, mainly fed on
three tree species: Ochroma pyramidale
(balsa), Euterpe precatoria (a species of
palm), and Cecropia peltata (trumpet
tree). This species may undergo some
form of nomadism to track food across
the landscape (Tobias and Brightsmith
2007, p. 132). Parrots may travel a few
kilometers to hundreds of kilometers in
search of food resources (Lee 2010, p. 8).
Because parrots feed primarily on fruits
and flowers, they are linked to the

fruiting and flowering patterns of trees;
fluctuations in abundance and
availability of these food sources may
change diets, result in movements to
areas with greater food availability, and
influence local seasonal patterns of bird
abundance (BLI 2011a, unpaginated; Lee
2010, p. 7; Tobias and Brightsmith 2007,
p. 132; Brightsmith 2006, p. 2; Renton
2002, p. 17; Cowen n.d., pp. 5, 23). In
some locations within its range, the
blue-headed macaw is not considered
uncommon and is recorded throughout
the year, but appears scarce in others or
varies seasonally in response to food
availability (BLI 2011a, unpaginated).
Geophagy, the intentional
consumption of soil, is known for
parrots (Brightsmith 2004a, p. 534). In
South America, parrots, including the
blue-headed macaw, gather at
riverbanks to consume soil; these sites
are referred to as ‘‘clay licks’’
(Brightsmith 2004c, pp. 134, 137;
Brightsmith 2004b, p. 5; Brightsmith
2004a, p. 535). Clay lick usage by blueheaded macaws is regular at several
sites, and occurs year-round at
Tambopata, Peru (Tobias and
Brightsmith 2007, p. 131). There have
been many theories proposed to explain
why birds consume soil, including
mineral supplementation, mechanical
aid to digestion, pH buffering, treatment
for endoparasites, and adsorption of
dietary toxins (Brightsmith 2004c, p.
143; Brightsmith 2004b, p. 1;
Brightsmith 2004a, p. 534–535). The
reasons for soil selection may vary, with
sites depending on the needs of the
birds and the characteristics of the soils
present (Brightsmith 2004a, p. 542).
Research in Peru has shown that parrots
consume soil to obtain sodium (mineral
supplementation) and assist in the
adsorption of dietary toxins
(Brightsmith 2004c, p. 134; Brightsmith
2004b, pp. 3–4; Brightsmith 2004a, pp.
541–542). Furthermore, research
conducted at the Tambopata Research
Center in Peru found that local clay lick
use by parrots varied seasonally, with
low use occurring at a time when
parrots appear to leave the area due to
low fruit availability and peaks
occurring during the breeding season
(Brightsmith 2004b, p. 3). Peak clay lick
use coincided with the breeding season
when adults feed clay to young chicks
during the period of maximum growth
and least resistance to natural toxins
found in their diet (Brightsmith 2004b,
p. 4).
The blue-headed macaw is reported to
occur in pairs or groups of three.
However, groups of 4 or more are
routinely reported throughout the range,
groups of 10 or more have been reported
from 13 localities, and 2 groups were
VerDate Mar<15>2010
19:14 Oct 11, 2011
Jkt 226001
reported to have 53 and 60 individuals,
respectively (Tobias and Brightsmith
2007, p. 131–132). Few courtship
displays have been described for
parrots, but are assumed to be simple
and include actions such as bowing,
wing-drooping, wing-flicking, tailwagging, and foot raising (Austin 1961,
p. 33). Most parrot species are
monogamous and remain paired for long
periods of time, even for life. The age at
which parrots reach sexual maturity
varies but, in general, is between 3 and
4 years in larger species and 1 to 2 years
in smaller species (Austin 1961, p. 32).
In captivity, the age in which the
species is able to breed ranges from 2.5
to 5 years (Tobias and Brightsmith 2007,
p. 132). The nesting season of the blueheaded macaw is not known, but for
other species of parrots and macaws
found at the same site, the nesting
season runs from June to November and
November to March, respectively
(Brightsmith 2006, pp. 7, 9). Although
nesting has not been recorded for the
blue-headed macaw, most parrots use
natural tree cavities or cavities within
cliffs (Lee 2010, p. 4). This species is
reported to have low reproductive
output in the wild (CITES 2002, p. 1),
but this may be based on little data
(Tobias and Brightsmith 2007, p. 32). In
captivity, the clutch size for blueheaded macaws is reported to be 2–4
eggs (Vit 1997, as reported in Tobias and
Brightsmith 2007, p. 132). Female
parrots generally incubate the eggs and
rely on the male for food, although in
some species the males contribute to
incubation (Lee 2010, p. 5; Austin 1961,
p. 33). Parrot chicks are born blind and
naked or with sparse down, which is
white in most species. The young of
small parrots develop slowly and
remain in the nest for 3–4 weeks (Austin
1961, p. 33). Adult longevity in the wild
is unknown for the blue-headed macaw,
but a congeneric (a species belonging to
the same taxonomic genus as another
species), the blue-winged macaw
(Primolius maracana), is reported to live
at least 31 years in captivity (Tobias and
Brightsmith 2007, p. 132).
Conservation Status
The blue-headed macaw is currently
classified as ‘‘vulnerable’’ by the
International Union for the
Conservation of Nature and listed in
Appendix I of the Convention on
International Trade in Endangered
Species of Wild Fauna and Flora
(CITES). Species included in CITES
Appendix I are the most endangered
CITES-listed species. They are
considered threatened with extinction,
and international trade is permitted

Summary of Factors Affecting the BlueHeaded Parrot
A. Present or Threatened Destruction,
Modification, or Curtailment of Habitat
or Range
One of the main threats to neotropical
parrot species, in general, is
deforestation (Snyder et al. 2000, p. 98).
The Amazon region has the world’s
highest absolute rate of deforestation
(Laurance et al. 2002, p. 738) and is
currently threatened by increasing legal
and illegal logging, road projects,
conversion of forests to agriculture,
cattle ranching, oil and gas extraction,
and mining (Lee 2010, p. 2; MacLeod
2009, p. 6; Cowen 2007, p. 9; Magrin et
al. 2007, p. 590; Tobias and Brightsmith
2007, p. 134; Hume et al. 2006, p. 10;
Asner et al. 2005, p. 480; Alverson et al.
2001, p. 113; Laurance et al. 2001, p.
309; Snyder et al. 2000, p. 98; Nepstad
et al. 1999, p. 505). However, in western
Amazonia, especially in Peru and
Bolivia where this species occurs, the
proportion of forest cover is still high
and large tracts of intact forests continue
to exist even though some forests have
been cleared around some major towns
(Finer et al. 2008, pp. 1, 6; Tobias and
Brightsmith 2007, p. 134; Kometter et al.
2004, p. 6). Information on the extent of
deforestation within the States or
departments where the blue-headed
macaw occurs is limited; most
information is at the national level and
may not necessarily apply to this
species, especially in Bolivia and Brazil
where it occurs just inside the borders
of these countries.
Logging
Tropical forests, especially the
Amazon, have experienced increasing
rates of deforestation for the past few
decades, largely for the conversion of
land to food crops or pastures, and
selective harvesting of timber has
increased in rate and extent (Granoff
2008, p. 553; Asner et al. 2005, p. 480;
Laurance 1999, p. 112; Laurence 1998,
p. 411).
Selective logging targets older, larger
trees that parrot species depend on for
nesting and food (Cowen 2007, p. 9;
Hume et al. 2006, p. 11). The loss of
these keystone trees may pose a threat
to parrot populations by creating a
shortage of suitable nesting sites,
increasing competition, and causing the
loss of current generations through an
increase in infanticide and egg
destruction (Lee 2010, pp. 2, 12). If not
managed correctly, selective logging
may also cause widespread collateral

jlentini on DSK4TPTVN1PROD with PROPOSALS5

damage to remaining trees, subcanopy
vegetation, and soils (Asner et al. 2005,
p. 480). An additional 10 to 40 percent
of the living biomass of a forest may be
damaged by a poorly managed logging
harvest process (Nepstad et al. 1999, p.
505) and can double the total amount of
forest degraded by human activities
(Asner et al. 2005, p. 481). The loss of
trees may influence the availability and
abundance of food sources for the blueheaded macaw and may result in
changes in diet or movement to areas
with greater food availability. Although
individual blue-headed macaws, nests,
or eggs may be affected by logging
activities, we have no information to
indicate impacts are occurring at a level
affecting the status of the species.
Typically, logging involves a low rate
of extraction (less than 3 cubic meters
(m3) per ha (106 cubic feet (ft3) per ac)
and, if implemented correctly, only
removes as many trees as the forest can
regenerate (Colitt 2010, unpaginated;
´
Rodrıguez and Cubas 2010, p. 78).
Because the valuable timber removed is
often very old, long intervals are needed
for timber stands to recover from harvest
(Laurance 1999, p. 114), and if
provisions are made for the regeneration
of these commercial trees, the effects of
logging on tree diversity and species
composition may be short-lived
(Fredericksen 2003, p. 10). In fact, if
well managed, selective logging can
mimic natural disturbances, and if
hunting pressure is low, most wildlife
species can persist in logged forests or
recolonize harvested areas from nearby
unlogged patches (Laurance 1999, p.
114). Studies have indicated a relatively
minor impact on some wildlife species
from logging, and among those that may
actually benefit are frugivorous birds,
such as the blue-headed macaw, due to
the positive impact on fruit abundance
(Fredericksen 2003, p. 11). Additionally,
frugivores usually tolerate fragmentation
better and are capable of using
deforested areas (Sekercioglu 2007, p.
285). Many parrots are not habitat
specialists and thrive in mosaics of
different successional habitats (Snyder
et al. 2000, p. 99). Many species of
lowland forest habitat seem to do
relatively well in modified human
environments, as long as a mosaic of
habitats in different successional stages
is maintained and poaching and
trapping are controlled (Snyder et al.
2000, p. 99). Although the blue-headed
macaw could potentially benefit from
some logging activities, we found no
information to what extent, if any, this
species benefits from these activities.
However, species experts have stated
that the possibility of the species

increasing with the spread of degraded
forests along rivers cannot be
discounted (Tobias and Brightsmith
2007, pp. 132–133) and Hennessey
(2011, pers. comm.) has stated that the
blue-headed macaw populations in Peru
and Bolivia have remained healthy.
Peru
With approximately 68 million
forested hectares (ha) (168 million acres
(ac)) covering 53 percent of its land area,
Peru has the second most extensive
forests in Latin America, after Brazil
(FAO 2011, p. 118; Salo and Toivonen
2009, p. 610). In the early 2000s,
Peruvian Amazonia experienced a series
of forestry reforms, including the
implementation of forest concessions
(forest leases), which led to a rush for
newly allocated timber resources (Salo
and Toivonen 2009, p. 609; Oliveira et
al. 2007, p. 2). More than 7 million ha
(17.2 million acres; approximately 10
percent of the country’s forest) are now
designated as forest concessions in the
regions of Ucayali, Loreto, Madre de
Dios, San Martin, and Huanco; another
18 million ha (44.5 million ac; nearly a
quarter of Peruvian forests) are still
potentially available for concession
designation in the near future
´
(Rodrıguez and Cubas 2010, p. 79; Salo
and Toivonen 2009, pp. 609–610).
The aim of the forestry reform was to
target issues such as control and
enforcement of forestry activities, as
well as illegal forestry activities (Salo
and Toivonen 2009, p. 610). Part of the
new forestry reform included a new
forestry law (See Factor D) which
classified Peru’s forests into 6
categories, including permanent
production forests. This category
includes those forests in which forest
concession contracts can be assigned. A
concession contract gives the holder the
right to exploit the resources within a
given area, but also gives the holder
responsibility to manage the resources
(Salo and Toivonen 2009, p. 611).
Studies have shown that forest
concessions in Peru have provided
forests with protection from
deforestation (Salo and Toivonen 2009,
p. 620; Oliveira et al. 2007, pp. 2–3).
Although we do not know the exact
location of the recently designated 7
million ha (17.2 million acres) of forest
concessions, they do not appear to have
impacted the blue-headed macaw, given
that the range has remained 90 percent
forested and there is no evidence in a
decline in the range or population of
this species. We do not know where the
18 million ha (44.5 million ac) of
potential forest concessions are located
in regards to locations of blue-headed
macaw; however, if located within the
PO 00000
Frm 00005
Fmt 4701

63483
range of this species, data suggest that
these concessions could provide forests
with protection against deforestation.
To date, the forests of Peru, including
large areas within the range of the blueheaded macaw, have mainly been
subjected to selective logging (Salo and
Toivonen 2009, p. 610; Tobias and
Brightsmith 2007, p. 134; Fredericksen
2003, p. 10), which has contributed to
only 2.5 percent of Peru’s overall
deforestation (Salo and Toivonen 2009,
p. 610). Nonetheless, there are reports of
illegal logging in Peru, including one
study that found evidence of illegal
logging within the Muruanahua Reserve
´
and Alto Purus National Park in Peru,
which is a known location for the blueheaded macaw (Upper Amazon
Conservancy 2010, unpaginated; World
Wildlife Fund in Indian Country Today
2007, unpaginated). However, there is
no evidence that selective logging
removes habitat for this species (Tobias
and Brightsmith 2007, p. 134).
Furthermore, it is possible that the blueheaded macaw could benefit from
logging given that frugivores tend to
benefit from logging due to the increase
in fruit availability, and lowland habitat
species, such as the blue-headed
macaw, do well in modified human
environments if successional forests are
left intact and poaching is controlled. In
addition, species experts have stated
that the possibility that the species is
increasing with the spread of degraded
forests along rivers cannot be
discounted (Tobias and Brightsmith
2007, pp. 132–133). Because the range
of the blue-headed macaw has remained
90 percent forested and there is no
evidence of a decline in either the range
or population, we have no indication
that selective logging or illegal logging
has impacted the blue-headed macaw.
Large areas within the range of the blueheaded macaw are slated for selective
logging (Tobias and Brightsmith 2007, p.
134); however, because there is no
evidence that selective logging removes
habitat, and in fact the species may
benefit from selective logging, we have
no reason to believe that future selective
logging activities in Peru will be a threat
to this species.
In summary, we find that
deforestation via current forest
concessions and selective logging have
not impacted the status of the blueheaded macaw based on the fact that the
range has remained 90 percent forested
and there is no evidence of a decline in
the range or population of this species.
Although we do not know the locations
of the forest concessions that may be
designated in the future, if they are
located within the range of the blueheaded macaw, they may provide

protection to blue-headed macaw
habitat from deforestation. Furthermore,
we found no information indicating that
the known areas of the blue-headed
macaw’s range that are slated for
selective logging will impact the status
of the species; in fact, it is possible that
the species could benefit. Additionally,
there are several conservation programs
being implemented in Peru to address
deforestation (see Conservation
Programs below). Therefore, we have
reason to believe that future
deforestation will not impact the status
of this species in Peru.

Bolivia
Approximately 57.2 million ha (141.3
million ac) (53 percent) of Bolivia’s total
area is forested (FAO 2011, p. 118); of
this forested area, 38.9 million ha (96.1
million ac) are within the Bolivian
Amazon and constitute 5 percent of the
total Amazon forest (Locklin and Haack
2003, p. 774). Large tracts of primary
forest remain in Bolivia, but it is likely
that some of these will be subjected to
logging (Fredericksen 2003, p. 13) as
forest products contribute to Bolivia’s
national exports (Byers and Israel 2008,
p. vi). As of 2006, 89 timber companies
held the rights to 5.8 million ha (14.3
million ac) of logging concessions
(Pacheco 2006, p. 208). The forests of
Bolivia have mainly been subjected to
selective logging (Salo and Toivonen
2009, p. 610; Fredericksen 2003, p. 10),
which has been done at very low levels
and with low human pressure, allowing
them to remain largely intact
(Fredericksen 2003, p. 10). There are
management issues that still need to be
addressed, including sufficient
regeneration time for commercial
species (Fredericksen 2003, p. 10).
However, given that Bolivia constitutes
only a small part of this species’ range,
and the fact that we found no
information indicating that logging has
impacted the blue-headed macaw range
or population in any of its range
countries, we have no reason to believe
that logging is a threat to the species in
Bolivia. Furthermore, we have no
information indicating any future
logging activities will impact the blueheaded macaw.
Brazil
Brazil contains 519.5 million ha (1.2
billion ac) of forested area, 62 percent of
the total land area (FAO 2011, p. 118).
Logging concessions total only 150,000
ha (370,658 ac) (Colitt 2010,
unpaginated). However, by the end of
2010, Brazil was to have auctioned off
an additional 1 million ha (2.5 million
ac) of forest concessions to private
companies in an effort to reduce the
VerDate Mar<15>2010

Jkt 226001
demand for illegal logging. Concessions
help establish control over public areas
usually occupied illegally (Colitt 2010,
unpaginated).
Logging is occurring in blue-headed
macaw habitat in extreme western
Brazil, but this species is a generalist
and can exist within degraded habitats.
ˆ
Rondonia and Acre are among Brazil’s
major timber-production states (Asner et
al. 2005, p. 480); however, this species
occurs just inside the border of western
Brazil and we found no information
suggesting that the range or population
of the blue-headed macaw have been
impacted by logging in Brazil and no
information indicating logging may
affect this species in the future.
Large areas within the range of the
blue-headed macaw have experienced,
or are slated for, selective logging
(Tobias and Brightsmith 2007, p. 134),
and designation of forest concessions
could potentially cause changes in landuse practices, perhaps affecting plant
and wildlife species composition and
diversity of an assigned area (Salo and
Toivonen 2009, p. 610; Fredericksen
2003, p. 10). However, BLI (2011a,
unpaginated) reports that ‘‘much of the
forest within the species’ range is still
intact, and although the Bolivian forest
is threatened by expansion of the
logging industry, this species may
benefit from the consequent patchwork
clearance.’’
Ninety percent of the range of the
blue-headed macaw remains forested,
and there is no evidence of a decline in
either the range or the population.
Logging could affect individual blueheaded macaws though the loss of food
or nesting resources; however,
considering the extent of intact forests
within the range of this macaw and no
evidence of a decline in the population
(Tobias and Brightsmith 2007, p. 134),
as well as the possibility that the blueheaded macaw is increasing with the
spread of degraded forests along rivers
(Tobias and Brightsmith 2007, pp. 132–
133), we have no evidence to suggest
that logging is affecting the blue-headed
macaw to a degree that it is affecting the
status of the species. Additionally, we
have no information to suggest that
logging may become a threat to the
status of the blue-headed macaw in the
future.
Roads and Infrastructure
Oliveira et al. (2007, p. 2) estimated
that 75 percent of the total Peruvian
Amazon forest damage was within 20
km (12.4 mi) of the nearest road. In
Bolivia, studies have detected smallscale roadside deforestation extending
over 30 km (18.6 mi) from major roads
(Steininger et al. 2001, p. 132). Studies
PO 00000
Frm 00006
Fmt 4701
Sfmt 4702
on the effects of roads on deforestation
in the Brazilian Amazon have shown a
30 percent forest loss within 10 km (6.2
mi) of roads and highways, with
highways causing an additional 20
percent forest loss within 11–25 km
(6.8–15.5 mi), and 15 percent loss
within 26–50 km (16–31 mi) (Zambrano
et al. 2010, p. 158). Despite the
deforestation occurring along roads and
highways, the range of the blue-headed
macaw is 90 percent forested, and we
found no information indicating that the
species has been impacted by roads or
any subsequent deforestation. In fact,
species experts (Hennessey 2011, pers.
comm. and Tobias and Brightsmith
2007, p. 134) indicate that this species
is doing well, despite some localized
impacts from infrastructure and roads.
The Initiative of the Integration of the
Regional Infrastructure of South
America (IIRSA) is a plan endorsed by
the South American presidents, which
includes around 350 infrastructure
projects, such as highways, bridges,
railways, ports, airports, and
transmission corridors, to accomplish
regional economic integration and
facilitate trade (Babbitt 2009, pp. 28–
29). At the center of this plan is the
nearly complete Transoceanic Highway,
a 1,000-km (621.3-mi) highway that
connects the Brazilian State of Acre to
the Peruvian coast, passing through
Puerto Maldonado (Garcia-Navarro
2009, unpaginated; Babbitt 2009, p. 28;
Tobias and Brightsmith 2007, p. 134)
and near several other locations in
which the blue-headed macaw has been
recorded, bisecting its range (Tobias and
Brightsmith 2007, p. 134). The blueheaded macaw occurs within the
immediate outskirts of Puerto
Maldonado, one of the areas with
significant disturbance, suggesting that
this species is not greatly affected by
anthropogenic pressures (Brightsmith
2009, pers. comm.; Tobias and
Brightsmith 2007, p. 129).
Future urban expansion in Puerto
Maldonado resulting from the highway
may put pressure on the protected area
of Tambopata (Delgado 2008, p. 27),
where the blue-headed macaw has been
recorded. Although the Transoceanic
Highway is not located within Bolivia,
the connection between Cobija, Bolivia,
´
and Brasileia, Brazil, allows Cobija, a
recorded location for the blue-headed
macaw, to benefit from the road project
and potentially grow in the future
(Delgado 2008, p. 31). Additionally,
IIRSA plans to build another highway
that would branch of from the
Transoceanic Highway in Rio Branco,
the capital of Acre. If completed, this
highway will run through the forests of
Serra do Divisor National Park, a known

location for the blue-headed macaw
(Babbitt 2009, p. 31). In spite of this
information, we found no indication
that the range, habitat, or population of
the blue-headed macaw has been
impacted by the Transoceanic Highway.
Given that the species has not been
adversely affected by road construction
or other infrastructure, we have no
information suggesting that the status of
this species may be impacted in the
future by the Transoceanic Highway.
Although there has been road
development within Peru, Bolivia, and
Brazil, and individual blue-headed
macaws could potentially be affected by
road development through the loss of
food and nesting resources, we have no
information indicating that the status of
the species has been adversely impacted
by this development in the past. The
range remains 90 percent forested and
there is no evidence that the range or
population has declined. Furthermore,
Brightsmith (2009, pers. comm.) notes
that although road construction and
related deforestation may affect part of
the blue-headed macaw’s range, habitat
analyses to date show no evidence that
deforestation will adversely affect the
species in the future.
Agriculture and Ranching
Logging and modern roads facilitate
infiltration into pristine forests by
migrant settlers who use slash-and-burn
methods for agriculture and cattle
pastures (Laurance 1998, p. 411). Slashand-burn agriculture involves the
clearing of land and burning of debris
(Locklin and Haack 2003, p. 775;
Nepstad et al. 1999, p. 505). Often, plots
are abandoned after only two or three
cycles, and then more forests are cleared
´
to establish new plots (Reyes-Garcıa et
al. 2007, p. 406; Duery and Vlosky 2005,
p. 10). Production may be limited to
subsistence farming if roads are in poor
condition or if the cost of transportation
is high. However, if roads are in good
condition and provide access to
international and national markets,
production may expand to cash crops
(Zambrano et al. 2010, p. 158; Locklin
and Haack 2003, p. 780).
Agriculture is considered the main
cause of deforestation in the lowlands of
Bolivia (Pacheco 2006, p. 215). With
pressures for agriculture expansion,
large areas are being cleared for both
soybean farms and cattle ranches
(Pacheco 2006, pp. 213, 216; Duery and
Vlosky 2005, p. 10; TNC 2001,
unpaginated: Laurance 1998, p. 411).
The San Buenaventura-Puerto Heath
road runs through the Madidi National
Park, a known location of the blueheaded macaw. The greatest humancaused impact along this road was the
VerDate Mar<15>2010

Jkt 226001
conversion of forest via slash-and-burn
agriculture, although rates of
deforestation were relatively low
(Locklin and Haak 2003, pp. 775, 778).
Forest clearance patterns of indigenous
communities practicing shifting
cultivation have been observed,
particularly along rivers, throughout
Beni, Pando, and La Paz (Steininger et
´
al. 2001, p. 131). Reyes-Garcıa et al.
(2007, p. 406) found that the Tsimane’,
a native Amazonian society within Beni,
practice slash-and-burn agriculture and
abandon their plots after one or two
cultivation cycles to establish new plots.
This society is also moving from
subsistence farming towards cash crops,
which requires additional forest clearing
and contributes to further deforestation
´
(Reyes-Garcıa et al. 2007, p. 407). We
have no information indicating that the
blue-headed macaw has been or will be
impacted by agriculture in Bolivia, and
given that Bolivia is such a small
portion of the species’ range, we have
no reason to believe agricultural
expansion is affecting or will affect this
species at the population level.
Current expansion of deforestation in
Bolivia Amazonia is also associated
with cattle ranching (Pacheco 2006, p.
216). Its contribution to deforestation is
expected to increase in the future due to
topographical limitations of mechanized
agriculture. In Beni, the impacts of
cattle ranching may be a greater
concern, as 65 percent of all the cattle
herds in Bolivia are located here
(Pacheco 2006, pp. 215–216). However,
the species’ range in Bolivia is limited
to just inside the border and we have no
information indicating that the blueheaded macaw has been impacted, or
could be impacted, by cattle ranching in
that area of its range.
In Brazilian Amazonia, cattle
production is the dominate land use in
deforested areas and is the main factor
driving deforestation (Pacheco 2006, p.
223; Laurance 1999, p. 113; Fearnside
1996, p. 21). Large-scale ranchers (those
that own over 100 ha (247 ac)) are
thought to be responsible for 70–75
percent of all the deforestation in this
region (Laurance 1999, p. 113).
Furthermore, illegal slash-and-burn
practices have already destroyed 20
percent of the Brazilian Amazon (Colitt
2010, unpaginated). The States of
ˆ
Rondonia and Acre, where the blueheaded macaw occurs, are currently
experiencing conversions of forest for
agriculture and cattle ranching (Tobias
and Brightsmith 2007, p. 134). However,
given this species’ limited range just
inside the border of Brazil and its ability
to thrive in altered habitat, coupled with
no information indicating that cattle
ranching has impacted, or will impact,
PO 00000
Frm 00007
Fmt 4701

63485
the blue-headed macaw within its
limited range in Brazil, we do not
believe that cattle production is
currently, or will be a threat to this
species, now or in the future.
Although the migration of settlers,
and the subsequent farming, has been
named by some as a contributing factor
to deforestation in Peru (Painter 2008,
unpaginated; Hume et al. 2006, p. 3), we
found little information on the extent of
deforestation due to agriculture. In
´
Manu National Park, 63,500 ha (156,911
ac) of 1.7 million ha (4.2 million ac)
were deforested up to the year 2005 for
agricultural activities (Cabieses 2009, p.
26). However, since 2006, the Integrated
Programme to Strengthen the Local
´
Capacity of Small Farmers of the Manu
Biosphere Reserve Buffer Zone of Peru
has worked with families within the
park to foster activities compatible with
organic farming and incorporate natural
resource management into agricultural
activities. By 2008, 530 families helped
reforest 151 ha (373 ac) with mostly
native species (Cabieses 2008, pp. 26–
27). In the area surrounding Cordillera
Azul National Park (a recorded location
for the blue-headed macaw), the rate of
deforestation due to the coffee and tea
plantations and cereal grain farms
(Chatterjee 2009, p. 557) has increased.
The core zone of the Park is largely free
of human inhabitants, with the
exception of one rancher with 220 ha
(543.6 ac) of pasture and some reports
of indigenous people in the
southeastern part of the Park. In 2008,
the Peruvian government granted a 20year contract to the Peruvian NGO
´
´
Centro de Conservacion, Investigacion y
Manejo de Areas Naturales Cordillera
Azue (CIMA) that allows CIMA to
manage the park under the supervision
of the State and according to clearly
defined guidelines. (Ostoic n.d., p. 1). In
addition, we found no information
indicating agriculture in any of the
range states has impacted, or will
impact, the blue-headed macaw, thus
we do not believe it will impact the
species in Peru, especially given the
limited and localized nature of
agriculture activities.
Agriculture and cattle ranching
activities are currently taking place
within the range of the blue-headed
macaw, especially within Bolivia and
Brazil. However, given that these two
countries make up a minimal part of the
species range, it is unlikely to have any
effect on the species. Although it is
possible that individual blue-headed
macaws could be affected by these
activities through the loss of food or
nesting resources, we have no
information indicating the species has
been adversely impacted by either

activity; in fact, the blue-headed macaw
seems to benefit from some fragmented
habitat. There is no evidence of a
decline in the range or population of the
blue-headed macaw and 90 percent of
the species’ range remains forested.
Both agriculture and cattle ranching are
expected to expand in the future;
however, we have no information on the
extent of this expansion and no
information indicating either activity
will be a threat to the species in the
future.

Oil and Gas
The western Amazon contains large
reserves of oil and gas, many that are yet
untapped (Finer et al. 2008, p. 1). Global
demand for energy and record oil prices
have launched unprecedented levels of
oil and gas exploration and extraction in
western Amazonia, with some of the
most intense activity occurring in Peru
(Kolowski and Alonso 2010, p. 917;
Babbitt 2009, p. 31; Finer et al. 2008,
p. 1).
National governments have delineated
specific areas, or blocks, that are zoned
for hydrocarbon (e.g., natural gas and
petroleum) activities; these blocks may
be leased to state and multinational
energy companies for exploration and
production (Finer et al. 2008, p. 1). In
western Amazonia, there are
approximately 180 oil and gas blocks
covering about 688,000 km2 (265,638
mi2), which are operated by at least 35
multinational companies (Finer et al.
2008, p. 2). These oil and gas blocks
may bring new access routes throughout
the area, contributing to deforestation,
as it did in eastern Amazonia and the
southern Brazilian Amazon (Finer et al.
2008, p. 6).
In 2003, Peru reduced royalties to
encourage investment and sparked an
exploration boom. As of 2008, 72
percent of the Peruvian Amazon was
zoned for oil and gas by the government
into 64 separate blocks; 48 of these
blocks are currently active, the others
may be subjected to active exploration
in the near future (Kolowski and Alonso
2010, p. 917; Finer et al. 2008, pp. 2, 5).
The only areas fully protected from oil
and gas activities are national parks and
national and historic sanctuaries, which
cover approximately 12 percent of the
Peruvian Amazon. However, 20 blocks
overlap with 11 less strictly protected
areas, such as communal reserves and
reserved zones (Finer et al. 2008, p. 2).
Although oil and gas exploration and
production are occurring in Peru, we
have no information indicating that the
blue-headed macaw has been impacted,
or will be impacted, by oil and gas
activities in Peru.

In Bolivia and Brazil, areas open to oil
and gas explorations are increasing
rapidly (Finer et al. 2008, p. 2). In
Bolivia, two leased blocks, covering
15,000 km2 (5,791 mi2), include large
parts of Madidi National Park, a
recorded location for the blue-headed
macaw, as well as other parks where the
blue-headed macaw has not been
recorded; exploration in this region is
imminent. The primary task of a newly
created oil company, comprised of the
State oil companies of Bolivia and
Venezuela, is to explore for oil in newly
created blocks surrounding Madidi
National Park. Many other blocks in
Bolivia overlap with protected areas
(Finer et al. 2008, p. 5). We have no
information indicating that the blueheaded macaw has been adversely
impacted by oil and gas exploration in
Bolivia; species experts have indicated
that there is no evidence of a decline in
the range or population of the blueheaded macaw (Tobias and Brightsmith
2007, p. 134) . Furthermore, we do not
have information to indicate that the
species will be impacted by future oil
and gas exploration in Bolivia.
In Brazil, a 400-km (248.5-mi) gas
pipeline was completed in 2009,
running from Urucus gas field (State of
ˆ
Rondonia) to Manaus (State of
Amazonas). Another 500-km (310.6-mi)
pipeline has been proposed to carry gas
ˆ
to Porto Velho in Rondonia.
Additionally, Brazil’s National
Petroleum Agency has announced plans
to look for oil and gas in the State of
Acre, on the border with Peru and
Bolivia (Finer et al. 2008, p. 5), an area
that contains known locations for the
blue-headed macaw. Oil and gas
exploration and production do not
necessarily impact parrots. Drilling
operations often have a smaller footprint
than other extractive activities, and this
is further reduced once the well is
installed. Further, we found no
information that existing oil and gas
operations have impacted any parrot
populations in any of the range
countries. Because there is no evidence
of a decline in the range or population
of the blue-headed macaw in Brazil, we
have no information indicating that the
blue-headed macaw has been impacted
by oil and gas exploration in Brazil.
Furthermore, we do not have
information to indicate that the species
will be impacted by future oil and gas
exploration in Bolivia.
Pending oil and gas projects are the
primary threats to Peru’s Camisea region
and Bolivia’s Madidi region (Finer et al.
2008, p. 6). Although individual blueheaded macaws could potentially be
affected by oil and gas explorations

resources, there is no evidence of a
decline in the range or population of the
blue-headed macaw, and we have no
information indicating that the species
has been adversely impacted by oil and
gas exploration. Furthermore, we have
no information to indicate that the
species will be impacted by future oil
and gas exploration.
Mining
Over the last decade, the price of gold
has increased 360 percent, with an
annual rate of increase of approximately
18 percent; subsequently, the number of
non-industrial gold mining operations
in developing countries has risen
(Swenson et al. 2011, p. 1). Many of
these operations are illegal, as they are
set up by residents without permits or
formal title to the land, and without an
environmental impact analysis or miner
education (Swenson et al. 2011, p. 1).
In Peru, the expansion of gold mining
has been encouraged by the
Transoceanic Highway, which has
drawn impoverished Peruvians into the
lowlands in search of a livelihood and
hoping to strike it rich (Garcia-Navarro
2009, unpaginated). Madre de Dios is
currently undergoing a new gold rush
due to the high price of gold, increased
oil and gas activities, and the
completion of infrastructure projects
(Hajek et al. 2011, in press). This region
is Peru’s third largest producer of gold
and accounts for 70 percent of Peru’s
artisanal (small-scale or subsistence
miner) gold production (Swenson et al.
2011, p. 2). Concurrent with increasing
annual gold prices, mining deforestation
has been increasing since 2003. From
2003 to 2006, annual mining
deforestation was approximately 292 ha
(721.5 ac) per year. From 2006 to 2009
this rate increased to 1,915 ha (4,732 ac)
per year, a six-fold increase (Swenson et
al. 2011, p. 4). Furthermore, Swenson et
al. (2011, pp. 4–5) found that mining
deforestation in this area is outpacing
deforestation due to settlements,
although this scenario might be different
for areas with more secondary roads,
which tend to correlate with higher
rates of deforestation. One study found
that forest recovery following smallscale gold mining was extremely slow
and qualitatively inferior to regeneration
following other human-caused
disturbances (Mol and Ouboter 2003, p.
202). However, these operations are
typically small and require very little
land-clearing. Given the relatively small
amount of land conversion for gold
mining, we found no information
indicating that deforestation via mining
has impacted the blue-headed macaw,
nor did we find any information
E:\FR\FM\12OCP5.SGM
12OCP5
jlentini on DSK4TPTVN1PROD with PROPOSALS5
Federal Register / Vol. 76, No. 197 / Wednesday, October 12, 2011 / Proposed Rules
indicating this species will be impacted
by mining in the future.
In addition to deforestation, impacts
to the environment from gold mining
stem from acid mine drainage and air
and water pollution from contaminants,
such as mercury. During gold
processing, mercury is released into
sediments, waterways and the
atmosphere. As parrots are known to
use riverside clay licks, they may be at
risk of mercury entering their systems
when they ingest soil particles. Many
developing countries have reached
agreements with large gold mining
companies that do not use mercury, but
regulating small-scale, artisanal mines
continues to be a struggle (Swenson et
al. 2011, pp. 1, 5). Furthermore, gold
miners might actively erode riverbanks,
which may include essential clay licks
used by parrots (Lee 2010, p. 12).
However, we have no information
indicating that mining has affected the
blue-headed macaw.
Permits for mining require an
environmental impact report. Madre de
Dios has the highest number of
unapproved mining permits in Peru;
moreover, there is little effective
enforcement of unapproved permits or
illegal miners, and therefore, little
incentive to apply for a permit
(Swenson et al. 2011, p. 2). Miners are
able to use waterways for transportation
and are capable of invading far reaches
of communities and protected areas.
Lack of funding, staff, and staff training
makes patrolling these remote areas
difficult (Swenson et al. 2011, p. 5).
Two of the three mining sites studied by
Swenson et al. (2011, p. 4) are located
less than 7 km (4.3 mi) from the
Amarakaeri Communal Reserve and less
than 70 km (43.5 mi) from Manu
National Park. In a study of 54 national
parks in Latin America, mining was
considered a threat in approximately 20
(37 percent) of the parks, of which 11
(55 percent) were located in Peru
(Swenson et al. 2011, p. 4). Peru’s newly
created Ministry of Environment is
working to control illegal mining, and a
recent effort was made through a
moratorium on new mining concessions
(Swenson et al. 2011, p. 5).
In addition to the major mining
growth centers, there are many small
expanding areas of mining scattered
across Madre de Dios, which are harder
to detect (Swenson et al. 2011, p. 5).
Rising annual gold prices and an
increasing number of miners setting up
illegal mines may fragment once large
areas of pristine forests. Although
individual blue-headed macaws could
potentially be affected by mining
through the loss of food or nesting
resources, we have no information that
VerDate Mar<15>2010
19:14 Oct 11, 2011
Jkt 226001
the species has been adversely impacted
by mining. In fact, this species tends to
benefit from patchwork clearance of
forests (BLI 2011a, unpaginated).
Furthermore, we do not have any
information indicating the species may
be impacted by future mining
operations.
Conservation Programs
A new mechanism is emerging that
may raise funds to protect forests from
deforestation, as well as mitigate climate
change. This mechanism is known as
‘‘reduced emissions from deforestation
and forest degradation’’ (REDD). As
forests are destroyed for logging,
mining, or oil and gas, the carbon stored
in the trees is released as carbon
dioxide, which adds to the
concentration of greenhouse gases; 20
percent of global greenhouse gas
emissions are thought to be from
deforestation (Chatterjee 2009, p. 557).
Lawmakers and businesspeople around
the world are beginning to consider
investing in REDD programs as a way to
mitigate climate change. Under this type
of program, developing countries would
be paid to protect their forests and
reduce emissions associated with
deforestation. Funds would come from
foundations, governments, or financial
agencies such as World Bank; industries
in developed countries would receive
credits for saving trees in developing
countries (Chatterjee 2009, p. 557). If
REDD projects are able to generate
revenue comparable to those of
activities such as logging and
agriculture, and revenues are distributed
equally among stakeholders, this would
give standing forests value and an
incentive for forest conservation (Hajek
et al. 2011, in press). REDD projects are
emerging in many regions (Hajek et al.
2011, in press); however, we do not yet
know the occurrence of these projects
within the range of the blue-headed
macaw and how successful these
projects will be.
Another program being implemented
is certification of forests. The basis for
certification is for consumers to be
assured by a neutral third party that
forest companies are employing sound
practices that will ensure sustainable
forest management. By being certified, a
company can differentiate their
products and potentially acquire a larger
share of the market (Duery and Vlosky
2005, p. 12). To be certified, companies
must follow standards set by the Forest
Stewardship Council (FSC).
Certification companies not only certify
forests, but also forest products that
come from well managed forests and
may also provide a means to track logs
and remove illegally logged trees from
PO 00000
Frm 00009
Fmt 4701
Sfmt 4702
63487
the market (Duery and Vlosky 2005, pp.
13–14; Kometter et al. 2004, p. 9). To
date, more than 670,000 ha (1.6 million
ac) of Peru’s forest have achieved FSC
certification (Rodriguez and Cubas 2010,
p. 78). Bolivia has the largest area of
FSC-certified tropical forests in the
world; by the mid-2000s, Bolivia
announced that 2.2 million ha (5.4
million ac) of humid tropical forests
were certified (Killeen et al. 2007, p.
600; Duery and Vlosky 2005, p. 14). In
2004, Brazil announced that 1.2 million
ha (2.9 million ac) of native Amazon
forests and 1.0 million ha (2.4 million
ac) of plantations were certified (WWF
2004, unpaginated). The FSC promotes
‘‘the equitable incorporation of social
and environmental considerations when
decisions are taken to manage forests.
Under FSC certification, civil and
indigenous rights are respected, areas of
high social and environmental
conservation value are maintained or
enhanced, natural forests are not
converted, highly hazardous pesticides
and genetically modified trees are
prohibited, and harvesting must meet
national laws and international
treaties.’’ Furthermore, forests that are
‘‘FSC certified forest products’’ are
verified from the forest of origin through
the supply chain. The FSC label ensures
that the forest products used are from
responsibly harvested and verified
sources (FSC n.d., unpaginated).
In 2008, Peru announced its intention
to reach zero deforestation within just
10 years. The Peruvian government
stated that more than 80 percent of the
country’s primary forests could be saved
or protected with about $20 million U.S.
dollars (USD) a year from the
international community. However,
there are major obstacles to achieving
this goal. Additionally, Peru launched
in 2010 its National Program for the
Conservation of Forests and Mitigation
of Climate Changes. This program aims
to preserve 54 million hectares (133
million acres) of the 72 million hectares
(178 million acres) of tropical forest in
the Peruvian Amazon, although it is
expected that the entire area consisting
of 72 million hectares will be included
(La Cruz 2010, unpaginated). Similarly,
Brazil announced a plan to cut
deforestation rates by 70 percent over
the next 10 years with the help of
international funding. Brazil’s plan calls
on foreign countries to find $20 billion
USD by 2021 (Painter 2008,
unpaginated). All three countries have
committed to protecting their forest
resources in the future and have moved
towards their goals to reach zero
deforestation by certifying nearly 4
million ha (10 million ac) of forests.

There are many obstacles to overcome to
reach these goals, including annual
funding. If these programs are
implemented and goals reached,
deforestation in the Amazon will be
significantly reduced.
Summary of Factor A
It is clear that the forests of the
Amazon are being deforested for various
economic activities, and deforestation
rates have been increasing for several
decades. How a species responds to this
type and level of habitat disturbance
depends on the preferences of the
individual species, and the distance of
undisturbed rainforest near disturbed
areas. Many parrots are not habitat
specialists and thrive in mosaics of
different successional habitats. Many
species of lowland forest habitat seem to
do relatively well in modified human
environments, as long as a mosaic of
habitats in different successional stages
is maintained and poaching and
trapping are controlled (Snyder et al.
2000, p. 99).
Although we do not know the exact
extent of current deforestation within
the specific areas occupied by the blueheaded macaw, especially within
Bolivia and Brazil where the species
occurs just inside the countries’ borders,
there is no evidence that deforestation
has impacted the blue-headed macaw.
Ninety percent of this species’ range is
still forested. There is no evidence of a
decline in the range or population and
populations within Peru and Bolivia
have remained healthy. At a minimum,
the population numbers 11,500
individuals (including immature
individuals), and this may be an
underestimate as the entire global range
has not been surveyed. Furthermore,
blue-headed macaws at the Tambopata
Research Center have been increasing
since 2000, and sightings of the blueheaded macaw in Peru have increased
over the last 10 years. Additionally, it
has been found in a wide range of
habitats, and is slightly more common
in degraded habitats than pristine
forests. The blue-headed macaw still
occurs on the outskirts of Puerto
Maldonado, Peru, one of the areas with
significant disturbance, suggesting that
this species is not greatly affected by
anthropogenic pressures. Species
experts have even suggested that the
blue-headed macaw may increase with
the spread of degraded forests along
rivers.
Although there is evidence that forest
habitat within the species range is
subject to selective logging, the
patchwork clearance as a consequence
of logging may benefit the species.
Furthermore, we found no information
VerDate Mar<15>2010
19:14 Oct 11, 2011
Jkt 226001
that selective logging has adversely
impacted the species. Additionally, road
construction and related deforestation
that are likely to affect the region in
which the blue-headed macaw occurs is
not likely to adversely affect the species.
It is possible that individual blueheaded macaws may be affected by
economic activities involving
deforestation, such as logging, road
development, agriculture and cattle
ranching, oil and gas exploration, and
mining, through the loss of food or
nesting resources; however, we have no
evidence to suggest that deforestation is
affecting the blue-headed macaw to a
degree that it is affecting the status of
the species. Based on the best scientific
and commercial information available,
we find that deforestation from various
economic activities, as discussed above,
is not adversely impacting the blueheaded macaw and has not affected the
range or status of the species.
Additionally, we do not anticipate
significant modification to the blueheaded macaw’s habitat or curtailment
of its range due to deforestation in the
foreseeable future. A vast amount of the
species’ range has remained forested
through current rates of deforestation.
Significant amounts of the forests
within Peru, Bolivia, and Brazil have
been FSC-certified, indicating they are
subject to sustainable harvesting, which
may improve its habitat. Furthermore,
all three countries have noted their
commitment to protecting their forests,
ensuring that harvest is done
sustainably, and each has a goal of
reaching zero deforestation within ten
years. Some of the operations within the
range of the blue-headed macaw that
contribute to deforestation have smaller
footprints than other extractive
activities and require little land clearing
(e.g., oil and gas operations and mining).
Although increased deforestation is
anticipated in Bolivia and Brazil, these
areas represent only a small portion of
the species’ range. Therefore, based on
the best scientific and commercial
information available, we find that
future deforestation from various
economic activities, as discussed above,
is not a threat to the status of the blueheaded macaw at this time.
We found no information suggesting
that habitat loss is a current threat to
this species or may become a threat to
this species in the future such that it
may contribute to the risk of extinction
of this species. Therefore, based on the
best available scientific and commercial
information, we find that the present or
threatened destruction, modification, or
curtailment of habitat or range is not a
threat to the blue-headed macaw in any
PO 00000
Frm 00010

Sfmt 4702
portion of its range now or in the
foreseeable future.
B. Overutilization for Commercial,
Recreational, Scientific, or Educational
Purposes
Parrots, in general, are long-lived with
low reproductive rates, traits that make
them particularly sensitive to increased
mortality (Lee 2010, p. 3; Thiollay 2005,
p. 1121; Wright et al. 2001, p. 711).
Hunting of parrots is widespread, and
locals are known to hunt macaws at clay
licks, which provide easy wait and
shoot opportunities, for food and
ornamental feathers (Tobias or
Brightsmith 2007, p. 134). Logging
operations are known to contribute to
increased hunting in areas opened by
the logging roads and subsequent
settlements (Lee 2010, p. 3; Hume et al.
2006, p. 11; Fredericksen 2003, p. 11).
However, there are no direct reports of
hunters targeting the blue-headed
macaw. Furthermore, hunters generally
target larger species of macaw for food;
since the blue-headed macaw is a small
species, it is unlikely that it is targeted
as a food source. Additionally, the
feathers of this species have not been
observed in local handicrafts, and
therefore, it is likely not targeted for this
purpose either (Tobias or Brightsmith
2007, p. 134).
Trapping parrots for the bird trade has
occurred since pre-European times, as
Amerindians valued macaws, parrots,
and feather ornaments as ritualistic and
trade objects (Snyder et al. 2000, pp. 98–
99). Today, owning a wild parrot as a
pet remains socially acceptable in most
neotropical countries, even if it is illegal
(Snyder et al. 2000, p. 99). Despite laws
to protect wild parrots, the black market
continues to supply a large part of the
pet parrot trade in national and
international markets. Illegal trade is
thought to contribute to the threatened
status of 66 parrot species worldwide,
including 27 species in South America
˜
(Gastanaga et al. 2010, p. 1).
In 1981, the blue-headed macaw was
listed in Appendix II of the Convention
on International Trade in Endangered
Species of Wild Fauna and Flora
(CITES). CITES is an international
agreement between governments to
ensure that the international trade of
CITES-listed plant and animal species
does not threaten species’ survival in
the wild. There are currently 175 CITES
Parties (member countries or signatories
to the Convention). Under this treaty,
CITES Parties regulate the import,
export, and reexport of specimens,
parts, and products of CITES-listed
plants and animal species (also see
Factor D). Trade must be authorized
through a system of permits and
E:\FR\FM\12OCP5.SGM

certificates that are provided by the
designated CITES Scientific and
Management Authorities of each CITES
Party (CITES 2010a, unpaginated).
In 2002, a CITES document proposed
an uplisting of blue-headed macaw from
Appendix II to Appendix I based on
increasing numbers of blue-headed
macaws in legal and illegal trade and
the effects of trade on a species with low
reproductive output (CITES 2002, pp. 1,
4–5). Sources cited in the document
stated that the blue-headed macaw was
offered in Brazilian markets by the
hundreds, possibly originating from
Peru, and was well known in Bolivian
markets. Sources also stated that traders
showed interest in buying more blueheaded macaws and for higher prices
(CITES 2002, p. 4). Prices for blueheaded macaws were found to be very
high, ranging from $300 to 12,500 USD.
Prices are set according to demand and
may be influenced by the species’ rarity.
Wright et al. (2001 in CITES 2002, p. 3)
found that prices above $500 USD were
significantly related to high poaching
rates. In view of the significant interest
in blue-headed macaws by aviculturist
and commercial breeders, increased
numbers of birds kept illegally, and the
assumed high demand based on prices,
capture pressure was believed to likely
increase and have detrimental impacts
to the species’ survival due to the
species rarity, low reproductive rate,
and limited distribution (CITES 2002,
pp. 5–6).
In January 2003, the blue-headed
macaw was uplisted to Appendix I of
CITES. An Appendix-I listing includes
species threatened with extinction
whose trade is permitted only under
exceptional circumstances, which
generally precludes commercial trade.
The import of an Appendix-I species
requires the issuance of both an import
and export permit. Import permits for
Appendix-I species are issued only if
findings are made that the import would
be for purposes that are not detrimental
to the survival of the species in the wild
and that the specimen will not be used
for primarily commercial purposes
(CITES Article III(3)). Export permits for
Appendix-I species are issued only if
findings are made that the specimen
was legally acquired and trade is not
detrimental to the survival of the
species in the wild, and if the issuing
authority is satisfied that an import
permit has been granted for the
specimen (CITES Article III(2)). On the
same day the blue-headed macaw was
uplisted to Appendix I, the Philippines
entered a reservation stating that it
would not be bound by the provisions
of CITES relating to trade of blueheaded macaws (CITES 2011,
VerDate Mar<15>2010
19:14 Oct 11, 2011
Jkt 226001
unpaginated). A reservation means that
the Philippines is treated as a nonCITES party with respect to the species
concerned. Countries with CITES
reservations may only trade with other
countries that have the same reservation
on the same species at the next level
lower, in this case Appendix II. If both
countries do not have a reservation on
that species, then the animal remains on
Appendix I.
Based on data obtained from United
Nations Environment Programme–
World Conservation Monitoring Center
(UNEP–WCMC) CITES Trade Database,
from the time the blue-headed macaw
was uplisted to CITES Appendix I in
January 2003 through 2009, 338
specimens of this species were reported
in international trade. Of this total, 276
were live birds, 61 scientific specimens,
and 1 body. In analyzing these reported
data, several records appear to be over
counts due to slight differences in the
manner in which the importing and
exporting countries reported their trade,
and it is likely that the actual number
of specimens of blue-headed macaws
reported in international trade to
UNEP–WCMC from 2003 through 2009
was 312, including 252 live birds, 59
scientific specimens, and 1 body. Of
these specimens, 58 (19 percent) were
reportedly exported into Mexico,
Belgium, and South Africa from Peru
(UNEP–WCMC 2011, unpaginated).
With the information given in the
UNEP–WCMC database, from 2003
through 2009 only 26 wild specimens of
blue-headed macaws were reported in
trade, and these were non-living
specimens traded for scientific
purposes; the other 286 specimens
reported in trade (252 live birds, 33
scientific specimens, and 1 body) were
captive-bred or captive-born specimens.
Through Resolution Conf. 8.4 (Rev.
CoP15), the Parties to CITES adopted a
process, termed the National Legislation
Project, to evaluate whether Parties have
adequate domestic legislation to
successfully implement the Treaty
(CITES 2010b, pp. 1–5). In reviewing a
country’s national legislation, the CITES
Secretariat evaluates factors such as
whether a Party’s domestic laws
designate the responsible Scientific and
Management Authorities, prohibit trade
contrary to the requirements of the
Convention, have penalty provisions in
place for illegal trade, and provide for
seizure of specimens that are illegally
traded or possessed. The Governments
of Peru and Brazil were determined to
be in Category 1, which means they
meet all the requirements to implement
CITES. Bolivia was determined to be in
Category 2, meaning legislation does not
meet the requirements to implement
PO 00000
Frm 00011
Fmt 4701
Sfmt 4702
63489
CITES; however, Bolivia has submitted
a CITES Legislation Plan and draft
legislation to the Secretariat for
comments (www.cites.org, SC59
Document 11, Annex p. 1). Generally
this means that Bolivia has not
completed all the requirements to
effectively implement CITES. However,
since the blue-headed macaw is listed as
an Appendix-I species under CITES,
commercial legal international trade is
very limited. Because the majority of the
specimens of this species reported in
international trade (81 percent) are
captive-bred or captive-born and the few
wild specimens reported in trade were
scientific specimens traded for scientific
purposes, we believe that international
trade controlled via valid CITES permits
is not a threat to the species. In
addition, Bolivia’s category 2 status
under the National Legislation Project
does not appear to be impacting the
blue-headed macaw.
There is evidence of a large market for
national and international parrot trade,
much of which involves illegally traded
birds in Peru, Bolivia, and Brazil
˜
(Gastanaga et al. 2010, p. 5; Lee 2010,
p. 12; Herrera and Hennessey 2007, pp.
296–297; Tobias and Brightsmith 2007,
p. 134; CITES 2002, p. 4). One study
found illegal trade of CITES AppendixI and Appendix-II listed species,
although the blue-headed macaw was
not recorded (Herrera and Hennessey
2007, p. 298). In Peru, there are reports
of trappers working unprotected clay
licks the blue-headed macaw is known
to use; however, it is not known
whether the species was targeted or if it
was actually caught (Tobias and
Brightsmith 2007, p. 134). It was
thought that foreign traders purchased
blue-headed macaws in and around
towns in Peru, Bolivia, and Brazil with
an unverified report of ‘‘hundreds’’
passing through some Brazilian markets
(CITES 2002 in Tobias and Brightsmith
2007, p. 134), but this report is from
before the species was listed in CITES
Appendix I in 2003. Three recent
studies on domestic parrot trade found
little to no evidence of blue-headed
macaws being traded, and certainly not
by the hundreds; one study found one
report of two birds being present in a
˜
single market (Gastanaga et al. 2010, pp.
5–6; Brightsmith 2009, pers. comm.;
Herrera and Hennessey 2007, pp. 298–
299). It appears that although there may
be some evidence of blue-headed
macaws in the illegal pet bird trade,
these numbers are likely low, as there is
no solid supporting data that this
species occurs in local markets in large
quantities (Brightsmith 2009, pers.
comm.), and furthermore, the report of
E:\FR\FM\12OCP5.SGM
12OCP5
63490
Federal Register / Vol. 76, No. 197 / Wednesday, October 12, 2011 / Proposed Rules
‘‘hundreds’’ of blue-headed macaws in
Brazilian markets referred to above
occurred prior to the listing of the
species in CITES Appendix I. What little
illegal international trade may be
occurring does not appear to have a
significant impact on the blue-headed
macaw, given a population ranging from
11,500 to 57,500 (Brightsmith 2009,
pers. comm.).
jlentini on DSK4TPTVN1PROD with PROPOSALS5
Summary of Factor B
We found no evidence indicating that
the blue-headed macaw is hunted as a
food source or for ornamental feathers.
Although trapping for the pet bird trade
may have occurred in large numbers, we
have no evidence that this is currently
occurring. Since the CITES Appendix-I
listing, legal commercial international
trade has been very limited.
Furthermore, recent studies of the parrot
trade in Peru, Bolivia, and Brazil found
no evidence of this species in markets,
suggesting that illegal trade may only be
occurring in small numbers, if at all, or
is very well hidden. In addition, we are
not aware of any information currently
available that indicates the use of this
species for any recreational or
educational purpose. According to the
WCMC Trade Database, from 2003
through 2009, 26 specimens were traded
for scientific purposes. Given the
estimated population size of 11,500–
57,500 individuals, we find that trade
for scientific purposes is insignificant.
Based on the best available scientific
and commercial information, we find
that overutilization for commercial,
recreational, scientific, or educational
purposes is not a threat to the blueheaded macaw in any portion of its
range now or in the foreseeable future.
C. Disease or Predation
Infectious diseases can pose many
direct threats to individual birds, as
well as entire flocks (Abramson et al.
1995, p. 287). Research on diseases
affecting the blue-headed macaw
specifically, either in captivity or in the
wild, is lacking. Most of the available
research on diseases in macaws and
parrots address captive-held birds;
information on the health of macaws in
the wild is scarce (Karesh et al. 1997, p.
368). It is not clear how prevalent
diseases which are common in birds
held in captivity affect this species in
the wild. Some of the common diseases
in macaws are discussed below.
Proventricular Dilatation Disease
One serious disease that has been
reported to infect psittacines is
Proventricular dilatation disease (PDD),
which is also known as avian
bornavirus (ABV) or macaw wasting

disease. It is a fatal disease that poses a
serious threat to domesticated and wild
parrots worldwide, particularly those
with very small populations (Kistler et
al. 2008, p. 1; Abramson et al. 1995, p.
288). This contagious disease causes
damage to the nerves of the upper
digestive tract, so that food digestion
and absorption are negatively affected.
The disease has a 100-percent mortality
rate in affected birds, although the exact
manner of transmission between birds is
unclear. In 2008, researchers discovered
a genetically diverse set of novel ABVs
that are thought to be the cause (Kistler
et al. 2008, p. 1). The researchers
developed diagnostic tests, methods of
treating or preventing bornavirus
infection, and methods for screening for
the anti-bornaviral compounds (Kistler
et al. 2008, pp. 1–15).
Psittacine Beak and Feather Disease
Psittacine beak and feather disease
(PBFD) has been documented in over 35
psittacine species, but all psittacines
should be regarded as potentially
susceptible (Abramson et al. 1995, p.
296). This viral disease, which
originated in Australia, affects both wild
and captive birds, causing chronic
infections resulting in either feather loss
or deformities of beak and feathers
(Cameron 2007, p. 82). PBFD causes
immunodeficiency and affects organs
such as feathers, the liver, and brain.
Suppression of the immune system can
result in secondary infections due to
other viruses, bacteria, or fungi. The
disease can occur without obvious signs
(de Kloet and de Kloet 2004, p. 2,394).
Birds usually become infected in the
nest by ingesting or inhaling viral
particles. Infected birds develop
immunity, die within a couple of weeks,
or become chronically infected. No
vaccine exists to immunize populations
(Cameron 2007, p. 82).
Newcastle’s Disease
Newcastle’s disease (ND) is a
contagious and fatal viral disease that
affects all species of birds, both
domestic and wild (South Dakota
Animal Industry Board (SD AIB) 2010,
p. 2). Introduction of this disease to
wild populations may come from
infected birds in aviaries, although this
is a low likelihood; exposure is more
likely to come from infected domestic
chickens or people carrying the disease
on clothing and footwear (Styles et al.
2008, p. 93). ND affects the respiratory,
nervous, and digestive systems.
Symptoms include sneezing, gasping for
air, nasal discharge, coughing, diarrhea,
depression, tremors, dropping wings,
paralysis, partial to complete drop in
egg production, thin shelled eggs,
PO 00000

swelling of tissue around the eyes and
in the neck, and sudden death (SD AIB
2010, p. 2; Abramson et al. 1995, p.
300). Once in a population, this disease
can cause severe mortality (Styles et al.
2008, p. 93). This disease is classified as
a Foreign Animal Disease in the United
States. The U.S. Department of
Agriculture, Animal and Plant Health
Inspection Service requires that all
imported birds be tested and
quarantined for disease before entering
the country. Birds illegally smuggled
into the United States are not
quarantined and, therefore, may
introduce this disease to captive birds
(SD AIB 2010, p. 4). There is no
treatment for this disease (Abramson et
al. 1995, p. 300).
Psittacosis
Psittacosis, also known as Parrot
Fever, is an infection caused by the
bacteria Chlamydophilia psittaci. An
estimated 1 percent of all birds in the
wild are infected and act as carriers.
Those that live in a stable environment
appear to have little complications from
the disease; however, stress, due to the
loss of food source or habitat, will
invoke the disease (Jones 2007,
unpaginated). In pet birds, psittacosis
can cause ruffled feathers, depression,
diarrhea, respiratory problems, loss of
appetite, weight loss, and even death.
This disease can be transferred to
humans and cause mild flu-like
infections or serious pneumonia.
Psittacosis can be treated with
antibiotics (Michigan Department of
Agriculture 2002, pp. 1–2).
Although there are many diseases that
could negatively affect macaws in
captivity and in the wild, we are
unaware of any information indicating
that any of those diseases are impacting
the blue-headed macaw at a level that
may affect the status of the species as a
whole and to the extent that it is
considered a threat to the species
(Brightsmith 2009, pers. comm.; World
Parrot Trust 2009, pers. comm.).
Predation
Although the blue-headed macaw has
not been recorded as the prey of other
predators, there are various bird and
mammal species found in the lowland
forests of the Amazon that could
potentially prey on macaws (CITES 202,
p. 3). While feeding at clay licks, parrots
are particularly vulnerable to raptors,
especially those that can catch them in
flight; eagles may be a potential
predator, as other macaws have been
observed leaving clay licks when an
eagle approaches (Burger and Gochfeld
2003, pp. 33; CITES 2002, p. 3).
Additionally, jaguars (Panthera onca)
E:\FR\FM\12OCP5.SGM
12OCP5
Federal Register / Vol. 76, No. 197 / Wednesday, October 12, 2011 / Proposed Rules
could also prey on macaws, given the
chance (Burger and Gochfeld 2003, pp.
33). In one study that found evidence of
nest predation in tree cavities in Peru,
the author suggested birds, such as
toucans, arboreal mammals, such as
monkeys, and possibly snakes are
significant nest predators (Brightsmith
2005, p. 79). Although blue-headed
macaws may be subject to predation,
there is no evidence that this is
occurring at a level that poses a threat
to the species (Brightsmith 2009, pers.
comm.; World Parrot Trust 2009, pers.
comm.).
Summary of Factor C
We are not aware of any scientific or
commercial information that indicates
disease or predation poses a threat to
this species. As a result, we find that
disease and predation are not threats to
the blue-headed macaw in any portion
of its range now or in the future.
D. Inadequacy of Existing Regulatory
Mechanisms
jlentini on DSK4TPTVN1PROD with PROPOSALS5
Peru
The blue-headed macaw is considered
‘‘vulnerable’’ by the Peruvian
Government under Supreme Decree No.
034–2004–AG (2004, p. 276855). This
Decree prohibits hunting, take,
transport, and trade of protected
species, except as permitted by
regulation. We found that hunting and
trade are not threats to the blue-headed
macaw at this time (Factor B), possibly
because this species may not be hunted
due to its smaller size. In addition, this
species has not been recently found in
the domestic trade markets within its
range, therefore, this regulation appears
to be contributing to adequate
protection against hunting and trade.
In 2000, Peru created a new Forest
and Wildlife Law (Ley Forestal y de
Fauna Silvestre No 27308) to govern the
forestland and improve control of
˜
wildlife trade (Gastanaga et al. 2010, p.
2; Granoff 2008, p. 533). This law
provides a regime for effective
regulation of efficient and productive
commercial forestry. Most notably, the
law requires management plans for all
forestry-related harvesting activities,
including long-term plans and annual
operating plans, which are submitted to
Instituto Nacional de Recursos
Naturales (INRENA), the Peruvian
government organization in charge of
the protection of flora and fauna of the
country (Granoff 2008, p. 552; WWF
2006b, unpaginated). However,
implementation is limited by the scarce
resources of INRENA (Indian Country
Today, 2007, unpaginated).
VerDate Mar<15>2010
19:14 Oct 11, 2011
Jkt 226001
The Forest and Wildlife Law also
regulates the commercialization of wild
species, provides minimum
requirements for their harvest,
collection, and transportation, and
establishes a maximum collection quota
for each species from their natural
˜
environment (Gastanaga et al. 2010, p.
2). INRENA annually sets a quota for
certain species, which is published in
the government newspaper. In 2007 and
2008, there were seven parrot species
listed for legal wildlife trade; however,
trade in the blue-headed macaw was not
˜
permitted (Gastanaga et al. 2010, p. 2).
As trade is not currently a threat to this
species (Factor B), this regulation may
contribute to adequate regulation of
trade in this species.
Recent studies by the Peruvian
Society for Environmental Law (SPDA)
have concluded that there are
approximately 5,000 laws and
regulations directly or indirectly related
to environmental protection and natural
resource conservation in Peru. However,
many of these are hindered by lack of
resources and enforcement capabilities
(Muller 2001, pp. 1–2). The forests of
the Amazon, including forests in Peru,
are being deforested for various
economic activities, and deforestation
rates have been increasing for several
decades. In spite of this, we found that
habitat loss as a result of deforestation
has not been a threat to this species;
therefore, it appears that although
existing forest regulatory mechanisms
are inadequate, the inadequacy of these
mechanisms in Peru is not affecting the
blue-headed macaw.
Bolivia
The 1975 Law on Wildlife, National
Parks, Hunting and Fishing (Decree Law
No. 12,301 1975, pp. 1–34) has the
fundamental objective of protecting the
country’s natural resources. This law
governs the protection, management,
utilization, transportation, and selling of
wildlife and their products; the
protection of endangered species;
habitat conservation of fauna and flora;
and the declaration of national parks,
biological reserves, refuges, and wildlife
sanctuaries, tending to the preservation,
promotion, and rational use of these
resources (Decree Law No. 12,301 1975,
pp. 1–34; Environmental Law Alliance
2003, p. 2). Although this law
designates national protection for all
wildlife, there is no information as to
the actual protections this confers to the
blue-headed macaw. Law No. 12,301
(1975, pp. 1–34) also placed into public
trust all national parks, reserves,
refuges, and wildlife sanctuaries.
However, there is no specific
information as to the governmental
PO 00000
Frm 00013
Fmt 4701
Sfmt 4702
63491
protections afforded within the
protected areas to either the blueheaded macaw or its habitat.
Additionally, this regulation is very
weak as it is 36 years old and the
institutional framework has changed
completely (Environmental Law
Alliance 2003, p. 2). We found that
hunting and trade are not threats to the
blue-headed macaw at this time (Factor
B); therefore, this regulation may
contribute to adequate protection
against unsustainable trade of the
species.
Bolivia passed an overarching
environmental law in 1992 (Law No.
1,333 1992), with the intent of
protecting and conserving the
environment and natural resources and
promoting sustainable development
(Environmental Law Alliance 2003, p.
1). Article 111 of this law states that all
persons involved in unauthorized trade,
capture, and transportation of wild
animals are subject to a 2-year prison
sentence and a fine equivalent to 100
percent of the value of the animal
(Herrera and Hennessey 2007, pp. 295–
296). However, there is no specific
legislation to implement this law
(Environmental Law Alliance 2003, p.
1). Nevertheless, we found that trade is
not a threat to the blue-headed macaw
at this time (Factor B); therefore,
existing regulations may contribute to
adequate protection against
unsustainable trade.
Before 1996, timber companies were
not required to write or use management
plans and based their harvesting on
selective extraction; this resulted in
poor forest management, resource
degradation, and a steep reduction in
timber values (Duery and Vlosky 2005,
p. 10). In 1996, Bolivia implemented a
new Forestry Law (Ley Forestal No.
1700) to regulate the protection and
sustainable use of forests and balance
the interests of society and the
economic and ecological health of the
country (Duery and Vlosky 2005, p. 10).
This law requires approved
management plans and compliance with
best management practices, including a
5-year forest management plan that
incorporates forestry inventory data,
timber stocking maps, and annual
operation plans (Duery and Vlosky
2005, p. 10; Fredericksen 2003, p. 10).
A typical forestry management plan
subdivides the forest into parcels; one is
used each year in a rotational system,
typically providing for a 19-year
regeneration period (Duery and Vlosky
2005, p. 10). Additionally, the
Deforestation and Slash-and-Burn Plan
that is part of this Forestry Law requires
a payment to the forestry office for
E:\FR\FM\12OCP5.SGM

slash-and-burn activities (Locklin and
Haak 2003, p. 780).
In Bolivia, selective logging has been
done at very low levels and with low
human pressure, allowing them to
remain largely intact (Fredericksen
2003, p. 10). Given that the species
occurs just inside the border of Bolivia,
and we found that habitat loss as a
result of deforestation is not a threat to
this species, it appears that the existing
forest regulatory mechanisms in Bolivia
may provide adequate protection for the
blue-headed macaw.
Brazil
In 1998, Brazil passed the
Environmental Crimes Law (Law No.
9605/98). Section I of this law details
crimes against wild fauna, which
include: the killing, harassment,
hunting, capturing, or use of any fauna
species without authorization (Clayton
2011, p. 4; UNEP, n.d., unpaginated).
Additionally, except for the State of Rio
Grande do Sul, commercial, sport, and
recreational hunting are prohibited in
Brazil. Penalties include a jail sentence
of 6 months to 1 year, and/or a fine; the
penalty is increased by half if the crime
is committed under certain
circumstances, including against rare
species or those considered endangered,
or within a protected area. However, it
is not considered a crime to kill an
animal when it is to satisfy hunger; to
protect agriculture, orchards, and herds
if authorized; or if the animal has been
characterized as dangerous. This law
also protects against other crimes
involving the fauna species of Brazil.
With respect to bird species, this law
prohibits inhibiting reproduction
without authorization; modifying or
destroying nests or shelters; selling,
offering, exporting, purchasing, keeping,
utilizing, or transporting eggs, as well as
products derived from fauna species
without authorization; and introducing
species into the country without license.
Although this law provides protection
to the fauna species of Brazil, it is more
permissive than the prior law, the Fauna
Protection Act (Law No. 5.197/1967),
which provided more severe
punishments (Clayton 2011, p. 4). We
found that hunting and trade are not
threats to the blue-headed macaw at this
time (Factor B); therefore, this
regulation may contribute to adequate
protection against trade.
Section II of the Environmental
Crimes Law details the crimes against
flora, which include the destruction and
damaging of forest reserves; cutting trees
in forest reserves, causing fire in forests;
extracting minerals from public forests
or reserves without authorization;
receipt of wood or vegetable products

Jkt 226001
for commercial or industrial purposes
without requesting a copy of the
supplier’s license; polluting the
environment at levels which may cause
damages to the health of human beings,
or death of animals or significant
destruction of plants; and research or
extraction of mineral resources without
authorization. Penalties vary according
to the crime and may be increased
under certain circumstances; for
example, the penalty may be increased
by one sixth to one third if the crime
results in a decrease of natural waters,
soil erosion, or modification of climatic
regime (Clayton 2011, p. 5; UNEP, n.d.,
unpaginated).
The Public Forests Management Law
(Law No. 11284, 2006) was passed to
protect and preserve forests that belong
to the Federal, State, or local
governments, with environmental,
economic, and social benefits. This law
is expected to help end illegal land
occupation by delineating public forests
(WWF 2006a, unpaginated); three
management models are provided:
creating conservation units (e.g.,
national forests), allocating forest areas
for community use free of charge (e.g.,
forest settlements), and signing forest
concession contracts (Patriota 2009, p.
615). The Brazilian government will
open some forest areas under 40-year
contracts to allow logging under a
sustainable development plan. Logging
is banned in nature reserves and
indigenous lands (WWF 2006a,
unpaginated).
In Brazil, there have been
improvements in environmental
legislation and public awareness;
however, enforcement capabilities are
lacking (Laurance et al. 2001, p. 309).
The forests of the Amazon, including
Brazil, are being deforested for various
economic activities, and deforestation
rates have been increasing for several
decades. However, this species occurs
just inside the border of Brazil and we
found that habitat loss as a result of
deforestation is not a threat to this
species; therefore it appears that the
inadequacy of existing forest regulatory
mechanisms in Brazil is not affecting
the blue-headed macaw.
Protected Areas
The Peruvian national protected area
system includes several categories of
habitat protection. Habitat may be
designated as any of the following: (1)
Parque Nacional (National Park, an area
managed mainly for ecosystem
conservation and recreation); (2)
Santuario (Sanctuary, for the
preservation of sites of notable natural
or historical importance); (3) Reserva
Nacional (National Reserve, for
PO 00000
Frm 00014
Fmt 4701
Sfmt 4702
sustainable extraction of certain
biological resources); (4) Bosque de
´
Proteccion (Protection Forest, to
safeguard soils and forests, especially
for watershed conservation); (5) Zona
Reservada (Reserved Zone, for
temporary protection while further
study is under way to determine their
importance); (6) Bosque Nacional
(National Forest, to be managed for
utilization); (7) Reserva Comunal
(Communal Reserve, for local area use
and management, with national
oversight); and (8) Cotos de Caza
(Hunting Reserve, for local use and
management, with national oversight)
´
(Rodrıguez and Young 2000, p. 330).
National reserves, national forests,
communal reserves, and hunting
reserves are managed for the sustainable
use of resources (IUCN 1994, p. 2). The
designations of National Parks,
Sanctuaries, and Protection Forests, are
established by supreme decree that
supersedes all other legal claim to the
land and, thus, these areas tend to
provide more habitat protection. All
other protected areas are established by
supreme resolution, which is viewed as
a less powerful form of protection
´
(Rodrıguez and Young 2000, p. 330).
Peru has 8 national parks and 41
additional protected areas (Chatterjee
2009, p. 558). The blue-headed macaw
has been recorded in at least 6 of these
areas: Cordillera Azul National Park
(Loreto, Huanco, and Ucayali); Manu
National Park (Madre de Dios and
´
Cuzco); Alto Purus Communal Reserve
and National Park (Madre de Dios); Los
Amigos Conservation Concession
(Madre de Dios); Tambopata National
Reserve (Madre de Dios); and BahuajaSonene National Park (Madre de Dios)
(Tobias and Brightsmith 2007, p. 134).
In Bolivia, habitat is protected either
on the national or departmental level
through the following designations: (1)
Parque (Park, for strict and permanent
protection of representative of
ecosystems and provincial habitats, as
well as plant and animal resources,
along with the geographical, scenic and
natural landscapes that contain them);
(2) Santuario (Sanctuary, for the strict
and permanent protection of sites that
house endemic plants and animals that
are threatened or in danger of
extinction); (3) Monumento Natural
(Natural Monument, to preserve areas
such as those with distinctive natural
landscapes or geologic formations, and
to conserve the biological diversity
contained therein); (4) Reserva de Vida
Silvestre (Wildlife Reserve, for
protection, management, sustainable use
and monitoring of wildlife); (5) Area
Natural de Manejo Integrado (Natural
Area of Integrated Management, where

conservation of biological diversity is
balanced with sustainable development
of the local population; and (6) Reserva
´
Natural de Inmovilizacion
(‘‘Immobilized’’ Natural Reserve, a
temporary (5-year) designation for an
area that requires further research before
any official designations can be made
and during which time no natural
resource concessions can be made
within the area) (Supreme Decree No.
24,781 1997, p. 3). Within parks,
sanctuaries and natural monuments,
extraction or consumption of all
resources are prohibited, except for
‘‘scientific research, eco-tourism,
environmental education, and activities
of subsistence of original towns,
properly described and authorized.’’
National protected areas are under the
management of the national
government, while departmental
protected areas are managed at the
department level (eLAW 2003, p. 3;
Supreme Decree No. 24,781 1997, p. 3).
There are 22 protected areas in
Bolivia covering 24 percent of its
territory (Byers and Israel 2008, p. vi;
Fredericksen 2003, p. 10). The blueheaded macaw has been recorded in at
least two of these areas: Madidi National
Park (La Paz) and Reserva Nacional
Amazonica Manuripi-Heath (Pando)
(Tobias and Brightsmith 2007, p. 134).
There are various regulatory
mechanisms (Law No. 11.516, Act No.
7.735, Decree No. 78, Order No. 1, Act
No. 6.938) in Brazil that direct Federal
and State agencies to promote the
protection of lands and that govern the
formal establishment and management
of protected areas to promote
conservation of the country’s natural
resources (ECOLEX 2007, pp. 5–7).
These mechanisms generally aim to
protect endangered wildlife and plant
species, genetic resources, overall
biodiversity, and native ecosystems on
Federal, State, and privately owned
lands (e.g., Law No. 9.985, Law No.
11.132, Resolution No. 4, Decree No.
1.922). Brazil’s formally established
protection areas were developed in 2000
and are categorized based on their
overall management objectives. These
include national parks, biological
reserves, ecological reserves, ecological
stations, environmental protection
areas, and national forests (Rylands and
Brandon 2005, pp. 612–618). These
areas allow varying uses and provide
varying levels of protection for specific
resources (Costa 2007, pp. 5–19). For
example, Biological Reserves are
restricted to a greater extent than the
National Parks. Official uses of reserves
include scientific study, environmental
monitoring, and scientific education
(Costa 2007, p. 9).
VerDate Mar<15>2010

Jkt 226001
There are 84 decreed protected areas
ˆ
within Rondonia, Brazil alone, covering
45 percent of the territory (Ribeiro et al.
2005, p. 1). The blue-headed macaw has
been recorded in one protected area, the
Serra do Divisor National Park, in Acre
(Tobias and Brightsmith 2007, p. 134).
In summary, the blue-headed macaw
occurs in at least 10 major protected
areas, covering a combined 110,216 km2
(42,554 mi2), or 18.7 percent of its
global range, although this does include
large areas of unsuitable habitat within
three of the protected areas (Tobias and
Brightsmith 2007, p. 134). In Peru, the
´
Alto Purus Communal Reserve and
National Park is surrounded by other
important protected areas, including
Manu National Park and the Tambopata
Reserve and Bahuaja Sonene National
Park; combined with Brazil’s and
Bolivia’s important natural protected
areas close to the border with Peru,
these areas constitute an important
protected corridor in South America
(ParksWatch 2003, p. 17).
Studies have shown that protected
areas have been successful in providing
protection from poaching, logging, and
other forest damage, especially when
compared to unprotected areas (Lee
2010, p. 3; Killeen et al. 2007, p. 603;
Oliveira et al. 2007, p. 1234; Asner
2005, p. 480; Ribeiro et al. 2005, p. 2;
Gilardi and Munn 1998, p. 641). There
is evidence of some habitat destruction
within protected areas, including
resource extraction, and information to
suggest habitat destruction within
protected areas is a potential future
threat, especially when in close
proximity to roads and subsequent
settlements and agriculture and pasture
conversion (Upper Amazon
Conservancy 2010, unpaginated;
Chatterjee 2009, p. 557; Cabieses 2009,
p. 26; Killeen et al. 2007, p. 603;
Oliveira et al. 2007, p. 1233; Ribeiro et
al. 2005, pp. 1–2; ParksWatch 2005a,
unpaginated; Fredericksen 2003, p. 10;
CITES 2002, p. 7).
A number of conservation
organizations have developed programs
to support the protected areas of Peru.
The Wildlife Conservation Society is
executing a wide range of projects
aimed at strengthening the management
of Madidi National Park. This program
is based on three main actions: (1) Park
management, (2) natural resources
management, and (3) scientific research
(ParksWatch 2005a, p. 35). CAREBolivia has also implemented projects to
raise local awareness on the importance
of watershed protection and sustainable
agricultural practices. Additionally,
CARE-Bolivia and the Wildlife
Conservation Society collaborated on
the park’s management plan, organized
PO 00000
Frm 00015
Fmt 4701

specific training courses for park
rangers, and donated basic management
equipment (ParksWatch 2005a, p. 38).
Also, since the Tambopata Reserve and
Bahuaja Sonene National Park was
created, a series of conservation and
research projects have been developed,
including, among others, Rainforest
Expeditions’ Macaw Ecological
Research Project (ParksWatch 2002, p.
7). The projects carried out by these
organizations will help conserve the
habitat of the park and will ultimately
benefit the blue-headed macaw.
We found no evidence that habitat
destruction within protected areas is a
threat to this species now or in the
foreseeable future; therefore, it appears
that the inadequacy of existing
regulatory mechanisms for protected
areas in Peru, Bolivia, and Brazil are not
adversely affecting the blue-headed
macaw.
International Wildlife Trade
The European Union (EU) Wildlife
Trade Regulation (Council Regulation
No. 338/97) went into effect in 1997.
The purpose of this regulation is to
protect wild animals and plants
currently or likely to become threatened
by international trade by regulating
trade in these species (UNEP–WCMC
n.d., unpaginated). The blue-headed
macaw is listed under Appendix A
(Council Regulation No. 709/2010
amending No. 338/97). Appendix A
includes species listed under CITES
Appendix I or species that may be in
demand for utilization in the EU or for
international trade, and which is either
threatened with extinction or so rare
that any level of trade would imperil the
survival of the species (Article 3(1)(a),
(b)). Additionally, there has been an EU
import suspension for the blue-headed
macaw from Bolivia since 1986 and
from Brazil since 1988 (Article 4.6(b)
(CITES 2002, p. 3; UNEP–WCMC n.d.,
unpaginated). As discussed under
Factor B, we do not consider
international trade to be a threat
impacting this species. Therefore,
protection under this Regulation is an
adequate regulatory mechanism.
The blue-headed macaw is listed in
Appendix I of CITES. CITES is an
international treaty among 175 nations,
including Peru, Bolivia, Brazil, and the
United States, entered into force in
1975. In the United States, CITES is
implemented through the U.S.
Endangered Species Act of 1973, as
amended. The Secretary of the Interior
has delegated the Department’s
responsibility for CITES to the Director
of the Service and established the CITES
Scientific and Management Authorities
to implement the treaty. Under this

treaty, member countries work together
to ensure that international trade in
animal and plant species is not
detrimental to the survival of wild
populations by regulating the import,
export, and reexport of CITES-listed
animal and plant species. As discussed
under Factor B, we do not consider
international trade to be a threat
impacting this species. Therefore,
protection under this Treaty is an
adequate regulatory mechanism.
The import of blue-headed macaws
into the United States is also regulated
by the Wild Bird Conservation Act
(WBCA) (16 U.S.C. 4901 et seq.), which
was enacted on October 23, 1992. The
purpose of the WBCA is to promote the
conservation of exotic birds by ensuring
that all imports to the United States of
exotic birds is biologically sustainable
and is not detrimental to the species.
The WBCA generally restricts the
importation of most CITES-listed live or
dead exotic birds except for certain
limited purposes, such as zoological
display or cooperative breeding
programs. Import of dead specimens is
allowed for scientific specimens and
museum specimens. The Service may
approve cooperative breeding programs
and subsequently issue import permits
under such programs. Wild-caught birds
may be imported into the United States
if they are subject to Service-approved
management plans for sustainable use.
At this time, the blue-headed macaw is
not part of a Service-approved
cooperative breeding program and does
not have an approved management plan
for wild-caught birds.
International trade was significantly
reduced during the 1990s as a result of
tighter enforcement of CITES
regulations, stricter measures under EU
legislation, and adoption of the WBCA,
along with adoption of national
legislation (Snyder et al. 2000, p. 99). As
discussed under Factor B, we found that
commercial legal international trade has
been very limited and illegal trade
currently occurs in small numbers, or is
very well hidden. Taking into
consideration the restrictions under the
EU Wildlife Trade Regulation, CITES,
and WBCA, and the lack of evidence for
this species occurring in substantial
numbers in the illegal pet bird trade, we
believe that these regulation are
adequately protecting the species from
international trade.
Summary of Factor D
We found no evidence that hunting or
trade poses threats to the blue-headed
macaw; therefore, existing regulatory
mechanisms addressing these activities
may be providing adequate protection
for this species. As discussed under
VerDate Mar<15>2010
19:14 Oct 11, 2011
Jkt 226001
Factor A, some deforestation, oil and gas
exploration and extraction, mining, and
infrastructure plans may occur in forests
in Peru, and perhaps within the limited
range of this species in Bolivia and
Brazil. However, we found that habitat
loss as a result of any of those activities
is not a threat to this species in any
portion of its range now or in the
foreseeable future; therefore, it appears
that the existing forest regulatory
mechanisms throughout the range of
this species is not adversely affecting
the blue-headed macaw.
E. Other Natural or Man-Made Factors
Affecting the Species’ Continued
Existence
We are not aware of any scientific or
commercial information that indicate
other natural or man-made factors pose
a threat to this species. As a result, we
find that other natural or man-made
factors are not threats to the blueheaded macaw in any portion of its
range now or in the future.
Finding
As required by the Act, we conducted
a review of the status of the species and
considered the five factors in assessing
whether the blue-headed macaw is
endangered or threatened throughout all
or a significant portion of its range. We
examined the best scientific and
commercial information available
regarding the past, present, and future
threats faced by the blue-headed macaw.
We reviewed the petition, information
available in our files, and other
available published and unpublished
information.
In considering whether a species may
warrant listing under any of the five
factors, we look beyond the species’
exposure to a potential threat or
aggregation of threats under any of the
factors, and evaluate whether the
species responds to those potential
threats in a way that causes an actual
impact to the species. The identification
of threats that might impact a species
negatively may not be sufficient to
compel a finding that the species
warrants listing. The information must
include evidence indicating that the
threats are operative and, either singly
or in aggregation, affect the status of the
species. Threats are significant if they
drive, or contribute to, the risk of
extinction of the species, such that the
species warrants listing as endangered
or threatened, as those terms are defined
in the Act.
We evaluated the potential threats to
the blue-headed macaw, including
habitat loss, national and international
trade, disease and predation, inadequate
regulatory mechanisms, and other
PO 00000
Frm 00016
Fmt 4701
Sfmt 4702
natural or manmade factors such as
climate change. We found no evidence
that this species is being hunted. Legal
international trade of this species has
been very limited and most of the birds
involved were captive-bred. We also
found that illegal trade, disease, and
predation were not threats to this
species. We had no information on other
natural or man-made factors on which
to evaluate the effects on the blueheaded macaw.
As discussed under Factor A, logging,
illegal logging, agriculture, ranching,
slash-and-burn activities, oil and gas
exploration and extraction, and illegal
mining are occurring in Peru, and
potentially in the area just inside the
borders of Bolivia and Brazil, and
deforestation rates have continued to
increase in those countries. The best
available scientific and commercial
information indicates that although
these activities could affect individuals
of this species, it does not appear that
these activities are affecting the species
at the population level. We did not find
information that the extent of future
deforestation or the potential impacts to
this species will occur at a level that
will elicit a species-level response and
contribute to the risk of extinction of the
species. All of the range countries of the
blue-headed macaw have laws and
regulations to protect the species, or
wildlife in general, and habitat. Existing
regulatory mechanisms have not
impacted the species such that it rises
to a level that it would be considered a
threat to the continued existence of the
species.
Based on the lack of threats of
sufficient imminence, intensity, or
magnitude acting on this species, we
find that the blue-headed macaw is not
in danger of extinction (endangered), or
likely to become endangered within the
foreseeable future (threatened),
throughout all of its range. Therefore,
we find that listing the blue-headed
macaw as a threatened or endangered
species is not warranted throughout all
of its range.
We request that you submit any new
information concerning the status of, or
threats to, the blue-headed macaw or its
habitat to our Branch of Foreign Species
(see ADDRESSES) whenever it becomes
available. New information will help us
monitor this species and encourage its
conservation.
Significant Portion of the Range
Having determined that the blueheaded macaw is not in danger of
extinction or likely to become so within
the foreseeable future throughout all of
its range, we must next consider
whether there are any significant
E:\FR\FM\12OCP5.SGM
12OCP5
jlentini on DSK4TPTVN1PROD with PROPOSALS5
Federal Register / Vol. 76, No. 197 / Wednesday, October 12, 2011 / Proposed Rules
portions of the range where the blueheaded macaw is in danger of extinction
or is likely to become endangered in the
foreseeable future.
The Act defines an endangered
species as one ‘‘in danger of extinction
throughout all or a significant portion of
its range,’’ and a threatened species as
one ‘‘likely to become an endangered
species within the foreseeable future
throughout all or a significant portion of
its range.’’ The term ‘‘significant portion
of its range’’ is not defined by the
statute. For the purposes of this finding,
a portion of a species’ range is
‘‘significant’’ if it is part of the current
range of the species and it provides a
crucial contribution to the
representation, resiliency, or
redundancy of the species. For the
contribution to be crucial it must be at
a level such that, without that portion,
the species would be in danger of
extinction or likely to become so in the
foreseeable future.
In determining whether a species is
threatened or endangered in a
significant portion of its range, we first
identify any portions of the range of the
species that warrant further
consideration. The range of a species
can theoretically be divided into
portions in an infinite number of ways.
However, there is no purpose to
analyzing portions of the range that are
not reasonably likely to be significant
and threatened or endangered. To
identify only those portions that warrant
further consideration, we determine
whether there is substantial information
indicating that: (1) The portions may be
significant, and (2) the species may be
in danger of extinction there or likely to
become so within the foreseeable future.
In practice, a key part of this analysis is
whether the threats are geographically
concentrated in some way. If the threats
to the species are essentially uniform
throughout its range, no portion is likely
to warrant further consideration.
Moreover, if any concentration of
threats applies only to portions of the
species’ range that clearly would not
meet the biologically based definition of
‘‘significant’’ (i.e., the loss of that
portion clearly would not reasonably be
expected to increase the vulnerability to
extinction of the entire species to the
point that the species would then be in
danger of extinction or likely to become
endangered in the foreseeable future),
such portions will not warrant further
consideration.
If we identify portions that warrant
further consideration, we then
determine their status (i.e., whether in
fact the species is endangered or
threatened in a significant portion of its
range). Depending on the biology of the
VerDate Mar<15>2010
19:14 Oct 11, 2011
Jkt 226001
species, its range, and the threats it
faces, it might be more efficient for us
to address either the ‘‘significant’’
question first, or the status question
first. Thus, if we determine that a
portion of the range is not ‘‘significant,’’
we do not need to determine whether
the species is endangered or threatened
there; if we determine that the species
is not endangered or threatened in a
portion of its range, we do not need to
determine if that portion is
‘‘significant.’’
Applying the process described above
for determining whether a species is
threatened in a significant portion of its
range, we considered status first to
determine if any threats or potential
threats acting individually or
collectively threaten or endanger the
species in a portion of its range. We
have analyzed the potential threats to
the blue-headed macaw throughout its
range and found that they occur at such
a low level that there is no effect to the
species.
Conclusion of 12-Month Finding
We do not find that the blue-headed
macaw is in danger of extinction now,
nor is it likely to become endangered
within the foreseeable future,
throughout all or a significant portion of
its range. Therefore, listing the species
as endangered or threatened under the
Act is not warranted at this time. We
request that you submit any new
information concerning the status of, or
threats to, the grey-cheeked parakeet to
our Endangered Species Program,
Branch of Foreign Species (see
ADDRESSES) whenever it becomes
available. New information will help us
monitor this species and encourage its
conservation. If an emergency situation
develops for the grey-cheeked parakeet
or any other species, we will act to
provide immediate protection.
II. Grey-Cheeked Parakeet (Brotogeris
pyrrhoptera)
A. Species Description
The grey-cheeked parakeet (Brotogeris
pyrrhopterus synonym Psittacus
pyrrhopterus) belongs to the family
Psittacidae, and is one of 8 recognized
species within its genus, with 17
recognized subspecies (Ribas et al. 2009,
p. 1713; Juniper and Parr 1998, p. 490;
Collar 1997; Forshaw 1989).
This species is characteristically
recognized by its distinctive greycheeks. It is also known as a pocket
parrot. Adults primarily have green
plumage with pale yellow on their
under parts. The forehead is grey with
a blue-green crown. The side of its head
and chin is pale grey and it has a slight
PO 00000

brown tinge on lesser and median wingcoverts. Its primary covert feathers are
dark blue; under wing coverts and
axillaries are orange. Its interior feathers
are narrowly edged with yellow, and the
legs are pale pink (Forshaw 1989).
The grey-cheeked parakeet is endemic
to southwestern Ecuador and
northwestern Peru (Nores 2004, p. 1;
Best et al. 1993). It occurs primarily in
forests in a narrow dry band of habitat
known as the Tumbesian (also known as
Tumbesan) Region (Best et al. 1996 p.
69; Best and Kessler 1995, p. 8, 155;
Parker et al. 1995, p. 202). This region
has distinct ecological characteristics
(Nores 2004, p. 149) based on drier
climate and local terrain. The greycheeked parakeet prefers dry, deciduous
forests dominated by Ceiba
trichistandra (Kapok or Ceibo tree)
(Williams and Tobias 1994 in Best et al.
1995, p. 237; IUCN 2008g). Smaller
numbers have been seen in semihumid
forest as well as fragmented forests, arid
scrubland, and semi-open agricultural
land where remnant stands of larger
trees that are suitable for nesting are
present (Forshaw 1989, p. 531). This
area is unique because it is at the
equator; its climate is influenced by the
Humboldt current, and its natural
boundary is defined by the Pacific Coast
and the Andes mountains (ParksWatch
2005b, p. 3). To the north and south of
´
this climate zone are the Choco wet
forest and the Peruvian coastal desert.
Three to nine months of the year are
arid (Best and Kessler 1995, p. 27). In El
˜
Nino years, which occur at 3–16-year
intervals, rainfall may be 200 times as
high as a very dry year (World Wildlife
Fund (WWF) 2007). The significant
biodiversity in this region has been
recognized for many years (ParksWatch
2005b, p. 3). Conservation International,
WWF, and BLI all consider this region
to be globally important due to the high
level of endemic species that exist here.
Although this species’ potential range
is estimated to be 9,300 km2 (3,591 mi2)
(BLI 2011b, p. 1), it does not occur
throughout its potential extent of
occurrence. Within this area, its actual
area of occurrence is confined to
suitable habitat, which contains areas
for nesting, breeding, and feeding. It
occurs in the lowlands, generally from
sea level to 300 meters (984 ft), but has
been observed as high as 1,550 m (5,085
ft) in the southern part of its range (Best
et al. 1992 in Best et al. 1995, p. 241).
In 1964, Brosset (1964, pp. 112–134)
reported it as being very common in
southwestern Ecuador; he described
large flocks that were seen in the
vicinity of banana plantations.
In Ecuador, this species has been
documented west of the Andes in the

Chone River district (Forshaw 1989, p.
531). In the early 2000s, it was observed
in the areas of Achiotes, El Faique,
Mangaurquillo, Manabi, Progreso,
Guayas, Los Rios, and El Oro, and in the
Sozoranga area of Loja (Bonaccorso et
al. 2006, p. 63; Freile et al. 2004, pp.
18–19; Ridgely and Greenfield 2001, p.
67). In addition to its native habitat, this
species has also been observed in
urbanized areas (Ridgely and Greenfield
´
2001, p. 67). It is found in El Canclon
Lagoon, which was declared a Ramsar
site in 1996, and which is one of the 32
identified wetlands in Ecuador’s coastal
region (Alava et al. 2007, p. 224). It has
also been observed in three protected
areas in southwestern Ecuador: the
Cerro Blanco Protected Forest (Sheets
2005, personal observation; Pople et al.
1996, p. 3), Manglares Churute
Ecological Reserve (MCER), and
Arenillas Military Reserve (Best et al.
1995, p. 241), which shares a small
portion of its border with Peru. MCER,
within Guayas Province, was created in
1979 and consists of 35,000 ha (86,487
acres (ac)) 40 km (25 mi) south of
Guayaquil (Pobles et al. 1996, p. 3).
MCER consists of mangrove stands, a
salt-flat area, and a forested section.
Cerro Blanco Reserve, within Guayas
Province, is 2,000 ha (4,942 ac). In 1995,
it was described as a small area of semievergreen forest on a ridge. It is
´
managed by Fundacion Natura and
´
Fundacion Pro-Bosque. The Arenillas
Military Reserve is 17,083 ha (42,213 ac)
in area and has limited access. It is
managed by military personnel and
requires prior authorization from the
Ministry of Defense to enter (https://
www.ambiente.gov.ec, accessed June 14,
2011).
In northwest Peru, this species is
reported to be locally common in
lowland dry deciduous forest (Walker
2001, p. 6; Parker et al. 1995, p. 212;
Parker et al., 1982). In 1995, this species
was described as being scarce at Campo
Verde and Cotrina, Peru (Parker et al.
1995, p. 212). This species has been
observed in the Tumbes Reserved Zone
(TRZ), specifically at El Caucho and
Quebrada Faical, with daily counts of
between 50 and 120 individuals (Best et
al. 1995, pp. 241, 242; Parker et al. 1995,
p. 212). TRZ is a part of the Northeast
Biosphere Reserve (NBR) which covers
231,402 ha (571,807 ac), and includes
the Cerros de Amotape National Park
and El Angulo Hunting Preserve
(Walker 2001, p. 1). In the late 1980s
and historically, this species was
documented as common in the NBR,
Tumbes Department (Best et al. 1995, p.
242; Wiedenfeld et al. 1985, p. 313). The
TRZ was formerly designated as the
VerDate Mar<15>2010
19:14 Oct 11, 2011
Jkt 226001
Tumbes National Forest (ParksWatch
2005b, p. 6), and was established in
1957 to protect against overharvest of
forest products (ParksWatch 2005b, p.
12). It is somewhat more protected than
it was in the past due to changes at the
border that have resulted from the Peace
Agreement between Peru and Ecuador,
and the subsequent decrease in the
pressures on the TRZ for natural
resources due to fewer human
inhabitants in the area (Walker 2001, p.
2).
The most recent population estimate
is prior to 1995, when it was estimated
that there were 15,000 mature
individuals of this species remaining in
the wild, principally in Ecuador (BLI
2011b, p. 1; Best et al. 1995, p. 242). At
that time, the population was estimated
to have experienced approximately a 70
percent population decline over 10
years (BLI 2011b, p. 1). This is
significant for two reasons: this estimate
was made only shortly after the
enactment of regulatory mechanisms
such as the implementation of trade
bans, and the estimate was also done
only a few years after trade restrictions
were put in place through the WBCA.
The population information prior to
1995 does not likely represent the
current status because regulatory
measures, particularly the
implementation of CITES and WBCA,
are currently in place which have
mitigated international trade, the major
threat to this species. Additionally, in
1991, the European Union banned the
import of this species (Best et al. 1995,
p. 234). International trade data
indicates that trade has dramatically
decreased.
There are several recent reports that
describe this species as common; large
flocks have recently been observed in
many areas within its range (WorldLand
Trust 2011, p. 2; Woods 2010, p. 34; Van
den Schoor 2007, p. 12; Elwonger et al.
2004, pp. 3, 20). A local report (2007)
documented this species in Guayas in
the Reserva Ecologica ManglaresChurute (https://www.xeno-canto.org,
Accessed September 28, 2011). It is
consistently seen in flocks on birding
trips (Denton 2009; Coopmans et al.,
2006; Coopmans 2005) in Southern
Ecuador. In Cerro Blanco Protected
Forest (BPCB), which is 14 km (8.7 mi)
west of Guayaquil, Ecuador, this species
was described as abundant in 1996,
with flocks of up to 40 observed (Pople
et al. 1996, p. 2). This area is owned by
La Cemento Nacional, Ecuador’s
national cement company, but the
reserve has been managed by the NGO
´
Fundacion Pro-Bosque since 1993
(Pople 1996, p. 1). In 1996, this species
was also observed in another area 25 km
PO 00000
Frm 00018
Fmt 4701
Sfmt 4702
(15.5 mi) northwest of BPCB consisting
of 600 ha (1,483 ac) known as Hacienda
Gonzalez, also owned by La Cemento
Nacional, that was established as a
forest reserve. This species was
described as not as abundant in this
reserve as in BPCB (Pople 1996, p. 2).
However, as of 2000, it was reported to
be still locally common in suitable
habitat remnants within its range
(Juniper and Parr 1998 in BLI 2011b, p.
1).
Additionally, various bird surveys are
conducted periodically in Peru and
Ecuador to determine presence and
absence in areas, and to conduct counts
of birds observed (Van den Schoor 2007,
p. 12; Elwonger et al. 2004, p. 20;
Walker 2001, p. 5). In 2001, a birding
trip to the TRZ encountered groups of
between 5 and 30 of this species and
described the occurrence of this species
as being common (Walker 2001, p. 5).
This species was also described as being
fairly common during a birding trip in
the Quebrada Faical area of the TRZ in
November and December 2004
(Elwonger et al. 2004, pp. 3, 20). In
2006, over 60 birds were observed in the
wild (Van den Schoor 2007, p. 12).
Although there is no current estimate of
this species’ population size, there are
several recent reports describing this
species as common; large flocks have
recently been observed in many areas
within its range (WorldLand Trust 2011,
p. 2; Woods 2010, p. 34; Van den Schoor
2007, p. 12; Elwonger et al. 2004, pp. 3,
20; Denton 2009; Coopmans et al., 2006;
Coopmans 2005). It is commonly found
in at least four reserves in Ecuador, and
one in Peru. In 2003 and 2007, it was
documented in Loja, Ecuador, where it
had been described as scarce during
1990–1991 surveys (Spencer, pers.
comm.; Williams and Tobias 1994 in
Best et al 1995, p. 242). An additional
consideration in their population is
their larger clutch size. Because they
generally lay between 4–6 eggs (https://
www.greycheekparakeet.com/
Genus_brotogeris.html, accessed August
22, 2011), they have a higher
reproductive potential than those
species that have a clutch size of 1–2
eggs.
Unlike other species within the
Brotogeris genus, the grey-cheeked
Parakeet does not generally congregate
in large flocks. Flocks of 4 to 10 birds
normally are observed (Freile et al.
2004), and they will sometimes flock
with other species (Best et al. 1995, p.
243). Brotogeris species primarily nest
higher in the canopy (Brightsmith 2000,
p. 529). They lay between 4 and 6 eggs,
with 5 eggs usually observed (Arndt
1986 in Best et al. 1986, p. 243). Their
average life span is thought to be

jlentini on DSK4TPTVN1PROD with PROPOSALS5
approximately 15 years (Brouwer et al.
2000, pp. 299–316).
Because parrots feed primarily on
fruits and flowers, they are linked to the
fruiting and flowering patterns of trees.
It is thought to be a seasonal migrant,
based on food availability (Parker et al.
1995, p. 212). This species is a food
generalist, consuming petals, seeds,
flowers, and fruits, particularly bananas
(Juniper and Parr 1998, p. 490).
Fluctuations in abundance and
availability of food sources may change
this species’ diet, resulting in
movements to areas with greater food
availability, and influencing local
seasonal patterns of bird abundance
(Lee 2010, p. 7; Brightsmith 2006, p. 2;
Renton 2002, p. 17; Cowen undated, pp.
5, 23).
This species exhibits preference for a
variety of nesting substrates, but
primarily nests in tree cavities (Juniper
and Parr 1998, p. 490; Forshaw 1989, p.
532; Berg in litt. in Best et al. 1985, p.
243). It prefers larger trees with larger
potential cavity size for its nests. The
grey-cheeked parakeet is known to form
nests in arboreal termite nests
(termateria) (Brightsmith 2000, p. 530).
Termites do not seem to be disturbed by
avian nesting behavior (Brightsmith
2000, p. 531; Harris 1985 in Best et al.
1985, p. 243). The species has also been
observed laying eggs on decaying wood
and moist moss in hollow tree limbs
and trunks (Harris 1985 in Best et al.
1985, p. 243). It shows preference for
particular tree species, such as:
Erythrina (coral erythrina), Bombax
(cotton tree), Chorisa or Ceiba (silkfloss), Cavanillesia platanifolia
´
(macondo, cuipo, or hamelı), Ficus (fig),
and Cecropia (trumpet tree) (Parker et
al. 1995, p. 212; Best et al. 1985, p. 243).
Conservation Status
This species is listed as endangered
by the IUCN. This categorization was
primarily based on rapid rates of
population decline caused by past
trapping for the pet trade (IUCN 2011,
p. 1). IUCN’s website states that ‘‘this
species qualifies as endangered because
it [was] affected by very rapid rates of
population decline caused by trapping
for the cagebird trade, plus habitat loss.
Future population declines are
projected to be slower, but still a serious
cause for concern.’’ However, this is
primarily based on information
compiled by Birdlife International,
which relies heaviliy on information
from before 1995. Note that IUCN
rankings do not confer any actual
protection or management. This species
has been listed in Appendix II of CITES
since 1981; it is listed on Appendix I of
the Convention on Migratory Species
VerDate Mar<15>2010
19:14 Oct 11, 2011
Jkt 226001
(CMS or Bonn Convention); and it is
protected by the WBCA. It is listed as
vulnerable in Peru (Peru Lista oficial del
Instituto Nacional de Recursos
Naturales 2011, p. 2; Supreme Decree
No. 034–2004–AG 2004, p. 276855), and
it is also considered vulnerable by the
Ecuador Government (Decree No. 3,516
of 2003; Unified Text of the Secondary
Legislation of the Ministry of
Environment (EcoLex 2003b, pp. 1–2
and 34). Additionally, in 1991, the
European Union (EU) banned the import
of B. pyrrhopterus from Peru (Best et al.
1995, p. 234). The EU ban and the
implementation of the WBCA effectively
halted the international trade in this
species, which was the largest driver of
its population decline (BLI 2011, p. 1 ;
Best et al. 1995, pp. 234–235).
Summary of Factors Affecting the GreyCheeked Parakeet
Potential factors that were suggested
to affect the species or its habitat or
range are evaluated in this section,
including: (1) Trapping for the pet trade;
(2) habitat destruction, primarily
through logging, conversion to
agricultural areas, and gravel extraction;
˜
(3) disease or predation; and (4) El Nino
events. Information pertaining to the
grey-cheeked parakeet in relation to the
five factors provided in section 4(a)(1) of
the Act is discussed below. In making
these findings, information pertaining to
each species in relation to the five
factors provided in section 4(a)(1) of the
Act is discussed below. In considering
what factors might constitute threats to
a species, we must look beyond the
exposure of the species to a particular
factor to evaluate whether the species
may respond to the factor in a way that
causes actual impacts to the species. If
there is exposure to a factor and the
species responds negatively, the factor
may be a threat, and during the status
review, we attempt to determine how
significant a threat it is. The threat is
significant if it drives or contributes to
the risk of extinction of the species such
that the species warrants listing as
endangered or threatened as those terms
are defined by the Act. However, the
identification of factors that could
impact a species negatively may not be
sufficient to compel a finding that the
species warrants listing. The
information must include evidence
sufficient to suggest that the potential
threat has the capacity (i.e., it should be
of sufficient magnitude and extent) to
affect the species’ status such that it
meets the definition of endangered or
threatened under the Act.

A. The Present or Threatened
Destruction, Modification, or
Curtailment of Its Habitat or Range
Habitat loss was indicated to be a
factor affecting this species (BLI 2011, p.
1). Although habitat loss can be one of
the most significant threats to wildlife,
particularly in developing countries, the
best available information does not
indicate that habitat loss is negatively
affecting this species as discussed
below. This species exists primarily in
southwest Ecuador and northwest Peru
˜
(Gastanaga et al. 2011, p. 1; BLI 2011,
p. 1; Alava et al. 2007; p. 1; Bonaccorso
et al. 2007, p. 61). In Peru, at the border
of Peru and Ecuador, this species exists
primarily in a protected area, the
Tumbes Reserved Zone (TRZ). Forms of
deforestation occur in and around the
TRZ and include timber extraction,
gravel extraction, encroachment, honey
harvest, and roads (ParksWatch 2005b,
pp. 8–9, 12). In addition, the park
boundaries have not been clearly
described or effectively protected, and
people have established crops in the
park. Land titles and ownership have
also been disputed (ParksWatch 2005b,
p. 10).
The activities described above have
occurred in the Tumbesian Region since
Peru and Ecuador were colonized; and
the region has undergone many changes.
In 1957, a total of 75,102 ha (185,581 ac)
were designated as a national forest
(now known as the TRZ) in order to
provide some protections to the
resources in this area. Significant
changes occurred particularly in the
1980s when both Peru and Ecuador
experienced economic problems. The
transfer of the presidency in 1985 was
Peru’s first transfer of power from one
democratically elected leader to another
in 40 years. During the early 1980s, Peru
experienced inflation, economic
hardship, and terrorism (U.S. State
Department 2011, p. 3), all of which had
significant implications with respect to
habitat degradation and deforestation.
Overall, however, the TRZ has for the
most part remained unaltered
(ParksWatch 2005, p. 3).
Species respond differently to habitat
fragmentation (Blanchet et al. 2010, p.
8). Deforestation is generally a process
of conversion of forests into a matrix
consisting of patches of remaining forest
at various stages of degradation and
remaining timber, agricultural lands,
urban areas, and pastures for grazing
(Turner 1996, p. 200). Various studies
have been conducted in order to try to
quantify effects of habitat loss and
fragmentation (Lees and Perez 2006, p.
206; Fahrig 2003, p. 487; Debinski and
Holt 2000, p. 342; Brooks et al. 1999a,

jlentini on DSK4TPTVN1PROD with PROPOSALS5
p. 211; Fahrig 1997, p. 603; Turner
1996, p. 200). However, if selective
logging is well managed, this practice
can mimic natural disturbances, and
many species can persist in logged
forests or they can recolonize harvested
areas from nearby unlogged patches
˜
(Putz et al. 2008, p. 1427; Pena-Carlos et
al. 2008, p. 1458; Laurance 1999, p.
114). Some studies have found that the
impact on certain wildlife species from
logging is minimal (Fredericksen and
Putz 2003, p. 1445). Some generalist
species, such as the grey-cheeked
parakeet, can successfully adapt to
changes in habitat particularly if they
have varied diets. Although this species
is endemic to Peru and Ecuador, it has
shown it can persist in altered habitats
and is common within several reserves
throughout its range. Not only does this
species exhibit success in using altered
habitats, its population appears to be
increasing in some parts of its range
(WorldLand Trust (WLT) 2011, p. 2).
WLT reports that it is increasing locally
in a new reserve, Buenaventura, which
is in the foothills of the Andes in El Oro
province, southwestern Ecuador (2011,
pp. 1–2).
Peru
Although a permanent logging ban
was enacted in the TRZ in 1974, it was
reported that wood was being illegally
harvested from the TRZ, processed at a
hardwood floor factory in Zarumilla
Department, and being exported to
Ecuador (ParksWatch 2005b, pp. 12, 14).
ParksWatch (2005, p. 15) reported that
people come from the cities of Tumbes,
Cerro Blanco, and Zarumilla to harvest
wood such as trumpet trees (Tabebuia
sp.), which is a species used for parquet
floors. Frequently these illegal
harvesters cross the border from
Ecuador (ParksWatch 2005b, p. 4). Most
of these trucks come through El
Tutumo, allegedly because the Instituto
Nacional de Recursos Naturales
(INRENA, translated as the National
Institute of Natural Resources) control
posts were often not staffed, and the
illegal timber harvesters took advantage
of their absence (ParksWatch 2005b, p.
14). These problems were intensified by
lack of security and coordination
(ParksWatch 2005, p. 3). Despite these
problems this species is described in its
range as being common. Current birding
trips to the TRZ encounter this species
frequently (Elwonger 2004, p. 6), and
there is no indication that logging
affects this species such that it is a
threat to the species overall.
Gravel extraction
ParksWatch reported that, as of 2003,
construction materials such as sand,
VerDate Mar<15>2010
19:14 Oct 11, 2011
Jkt 226001
rocks, and gravel were regularly
extracted from La Angostura Creek
which is part of the buffer zone of TRZ
(ParksWatch 2005b, p. 16). The heavy
machinery associated with the gravel
pits also has secondary impacts
(ParksWatch 2005b, p. 16). These
impacts include compaction of soil by
the trucks, which can cause hydrologic
changes, damage to wildlife and plants,
erosion, and increased recovery time for
vegetation communities. However, there
is no indication that this activity affects
this species.
Roads
Illegal activities can increase with the
construction of roads, leading to
increased access by humans (Fimbel et
al. 2001 in Lee 2010, p. 3). Roads are
planned by all levels of government and
may encourage legal and illegal
activities such as agriculture, cattle
ranching, poaching, or logging (Nature
and Culture International (NCI 2011, p.
1)). However, roads in the TRZ were
˜
destroyed during the El Nino event of
1997–1998, and as of 2001, there were
no plans to rebuild them (Walker 2001,
p. 2). This lack of road access minimizes
human entry into the species’ habitat. In
addition, the human population density
in this area is low—there are two
communities consisting of
approximately 330 people (ParksWatch
2005, p. 9), and there is no evidence to
suggest that roads used for gravel
extraction are negatively affecting the
species.
Honey Harvest
Within the TRZ, detrimental practices
of honey harvesting occur (ParksWatch
2005b, p. 18), which can further degrade
habitat. Bees generally have positive
ecosystem effects—they pollinate native
species and they contribute to the
biodiversity of ecosystems such as the
TRZ (Kearns et al. 1998, pp. 83, 90;
Pearson and Dressler 1985, p. 38).
However, due to the demand for honey,
non-native bee colonies (which are
aggressive—Apis melifera for example)
are being established (ParksWatch
2005b, p. 18). Non-native bees often
outcompete native bees (Kearns et al.
1998, p. 93), which have a vital role in
ecosystems. Some bees within the
Centris genus (which are likely native to
this region) use decaying wood as
habitat (Kearns et al. 1998, p. 90).
Decaying wood is also used by the greycheeked parakeet as nesting substrate.
The use of decayed wood by bees may
discourage the grey-cheeked parakeet
from using it as nesting substrate.
Additionally, in order to obtain honey,
some harvesters may chop down greycheeked parakeet nesting trees, which
PO 00000
Frm 00020
Fmt 4701
Sfmt 4702
contributes to habitat degradation. The
practice of honey harvesting may affect
individual birds; however, there is no
evidence that this practice occurs to an
extent that it is a threat to the species
or is likely to occur in the future.
Ecuador
There is less information available
with respect to the present or threatened
destruction, modification, or
curtailment of the grey-cheeked
parakeet’s habitat or range in Ecuador.
We know that this species is observed
regularly in southwest Ecuador (Woods
2010, p. 34; Bonaccorso et al. 2007, p.
64, Van den Schoor 2007, p. 12). It has
been documented in the areas of
Achiotes, El Faique, and Progreso and
´
Jorupe reserve, Macara, Loja province,
Buenaventura Reserve, El Oro Province,
and Cerro Blanco Reserva, Guayas.
There are several accounts of this
species being documented between the
early 2000s and 2011 (Bonaccorso 2007,
p. 64; https://www.xeno-canto.org,
www.avesecuador.com, https://
ibc.lynxeds.com/species/grey-cheekedparakeet-brotogeris-pyrrhopterus, all
accessed August 22, 2011). Flocks of up
to 12 birds have been observed recently;
one group of 60 was observed in 2006
(Van den Schoor 2007, p. 12). A recent
´
report indicated that in El Canclon
Lagoon, Ecuador, cattle ranching,
deforestation, agriculture development
(rice crops and farms) may be affecting
the species’ habitat (Alava et al. 2007, p.
224). However, this species is a habitat
generalist that seems to persist in
altered habitat, and it is frequently
observed on birding trips in Ecuador
(Greenfield 2011, p. 1; Woods 2010, p.
34; Van den Schoor 2007, p. 12).
Additionally, there is no recent
information on forest cover (Food and
Agriculture Organization 2011, accessed
June 17, 2011). Various estimates
indicate that around 50 percent of
Ecuador’s land area is covered with
forests (about 12 million ha (29.6
million ac)) (Sierra et al. 1999, p. 135;
STCP Engenharia de Projetos Ltda.
(STCP) 2006, unpaginated). However, in
Ecuador’s Tumbesian Region, 5,600 km2
(2,162 mi2) are designated as protected
forests. Of these, 25 percent of this area
retains the original composition of
species (Bonaccorso et al. 2007, p. 64).
Bonaccorso et al. (2007, p. 64) also
concluded that all of the areas where the
grey-cheeked parakeet was observed had
relatively extensive forest based on
satellite imagery. Although
southwestern Ecuador is densely
populated, habitat has been reserved for
wildlife (such as Jorupe Reserve,
Buenaventura Reserve, and Cerro
Blanco Reserve), and this species

appears to remain common in these
protected areas.
The Ecuadorian government
recognizes 31 different legal categories
of protected lands (e.g., national parks,
biological reserves, geo-botanical
reserves, bird reserves, wildlife reserves,
etc.) (see Factor D). As of 2006, the
amount of protected land (both forested
and non-forested) in Ecuador totals
approximately 4.67 million ha (11.5
million ac) (ITTO 2006, p. 228). As of
2006, 38 percent of these lands had
appropriate conservation measures in
place to be considered protected areas
according to international standards
(i.e., areas that are managed for
scientific study or wilderness
protection, for ecosystem protection and
recreation, for conservation of specific
natural features, or for conservation
through management intervention). At
that time, 11 percent had management
plans (ITTO 2006, p. 228).
Additionally, since 2006, other factors
have occurred that are improving the
quality of the habitat in this species’
range. Ecotourism is occurring in areas
where this species occurs, which is
bringing awareness and funding for
conservation projects. The success of
ecotourism and land protection has
been demonstrated in the past,
particularly in Ecuador (Wunder 1999,
p. 18). Ecotourism is characterized by
small groups working in remote
locations that have not yet been largely
affected by commercialization (Lindsay
2003, p. 2) Ecotourism is an opportunity
to preserve ecosystems and biological
diversity by generating income to
support conservation and research
efforts. Ecotourism fees provide a
mechanism for long-term protection of
the land and its resources. In addition,
NGOs are involved in working with
´
Ecuador’s protected areas. Fundacion
Jocotoco is a key player in Ecuadorian
conservation and ecotourism; it was
established to protect areas that are
important for the conservation of
endangered birds and their habitats.
´
Some NGOs such as Fundacion Jocotoco
are buying additional land that will be
protected in southern Ecuador
(www.worldlandtrust.org/projects/
ecuador-reserves, accessed September
14, 2011).
Although within this species’ existing
range some habitat has decreased in the
past, since that time both the Ecuador
and Peruvian have formally protected
this species’ habitat (Bonaccorso et al.
2006, p. 61). Some habitat loss,
conversion to other uses, and
degradation within some parts of the
grey-cheeked parakeet’s range occurs,
but we do not have information as to the
extent of degradation (ParksWatch
VerDate Mar<15>2010
19:14 Oct 11, 2011
Jkt 226001
2005b, pp. 9, 12). Studies have found
that conditions inside the parks
compared with the surrounding areas
were in significantly better condition
than their surrounding areas (Bruner et
al. 2001, p. 125). In 40 percent of parks,
land that had formerly been under
cultivation and that was incorporated
into park boundaries had recovered.
This subsequently led to an actual
increase in vegetative cover. The study
found that 83 percent of parks were
successful at mitigating encroachment
(Bruner et al. 2001, p. 125). This was
confirmed in a more recent study that
found that forests in conservation units
were four times better at protecting
against deforestation than unprotected
areas (Oliveira et al. 2007, p. 1235). In
further support, ParksWatch (2005, p. 3)
reports that the forests of TRZ have
remained unaltered for centuries and
have become a wildlife refuge.
Additionally, both Ecuador and Peru are
implementing policies and actions to
combat deforestation and habitat
degradation (refer to Factor D) and this
will continue into the future.
Since the Peace Accord between Peru
and Ecuador was signed in 1998, the
habitat has experienced dramatic
changes in the TRZ (Walker 2001, p. 2).
The Peace Accord between Peru and
Ecuador was to resolve border
differences that had sparked violent
confrontations. Prior to 1988, military
troops were based at El Caucho near
Quebrada Faical, Peru. Apparently,
hunting supplemented the diet of the
troops, and since the Peace Accord,
many game species have returned and
have become more prevalent according
to local communities (Walker 2001, p.
2). These species likely play a
significant role in the grey-cheeked
parakeet’s ecosystem; they may serve to
distribute seeds, contribute to the
quality of leaf fodder, or other roles that
are not as evident (Estes et al. 2011, p.
301). As of 2001, the former military
posts are only manned by two Peruvian
border police, and although the guards
continue to supplement their diets with
hunting, the pressure is less severe on
typical game species (Walker 2001, p.
2). In 2001, the quality of habitat on the
Peruvian side of this border was
characterized as excellent and
improving. On the Ecuadorian side,
habitat was described as more inhabited
by humans and having limited suitable
habitat—cattle and towns had replaced
forested areas (Walker 2001, p. 2).
Despite the increase in human
inhabitants in this area, this species
exhibit success in using altered habitat
and it exists in protected areas where
ecotourism and environmental

education is prevalent. The greycheeked parakeet is commonly seen in
reserves and protected areas, and in
some cases there are anecdotal reports
that it is actually increasing in
population (WLT 2011, p. 2).
Conservation Programs
The biodiversity of the southern
Ecuadorian area is recognized by the
government; and the link between
ecotourism and conservation has
strengthened in the past decade. In
1999, a case study about ecotourism
focusing on Ecuador was published that
highlighted the link between income
from ecotourism and forest conservation
(Wunder 1999, p. 1). Since 2001, many
efforts have been initiated to protect,
conserve, and improve habitat in this
species’ range. These activities are
achieved through ecotourism,
environmental education, and other
projects. Land is being purchased to
designate formally as reserves (https://
www.wanconservancy.org, accessed
September 14, 2011). Additionally, the
United States pledged $40 million for
the Peru-Ecuador border integration
project (U.S. State Department 2011b, p.
7) and another $4 million to support
Peruvian and Ecuadorian de-mining
efforts along their common border
(https://www.state.gov/r/pa/ei/bgn/
35762.htm, accessed June 10, 2011). The
presence of fewer military troops is
alleviating pressure on the TRZ. All of
these activities are likely to reduce any
impacts to species and habitat along the
border.
Many collaborative and innovative
conservation projects to conserve land
have occurred recently. Several NGOs
such as Birdlife International,
WorldLand Trust, Nature and Culture
International, and local organizations
´
such as Fundacion EcoCiencia, Loro
Parque Fundacion, ProNaturaleza, and
´
Fundacion Pro-Bosque, are working to
protect areas in Tumbesian Ecuador.
´
Fundacion EcoCiencia’s mission is to
conserve biological diversity through
scientific research, recovery of
traditional knowledge, and
environmental education. The
Foundation was created in 1989 and has
six program areas: Biodiversity Research
and Monitoring; Environmental and
Conservation Training Capacity; Natural
Resources Management, Environmental
Policies; and Information and
Environmental Economy. This NGO has
contributed towards research of the
grey-cheeked parakeet. The Loro Parque
´
Fundacion (LPF) is headquartered in
Loro Parque, Tenerife, Spain, and works
to conserve threatened parrot species
and their habitats, through education,
applied research, responsible breeding

programs, and community-based
conservation activities that use these
species as ambassadors for nature. LPF
has also contributed funding towards
projects that involved the grey-cheeked
parakeet. ProNaturaleza (Peruvian
Foundation for the Nature Conservancy)
was created in 1984. It is dedicated to
the conservation and preservation of
Peru’s environment, particularly
sustainable use of the natural resources.
ProNaturaleza has been involved in the
protection of the TRZ by promoting
local involvement, establishment of
agreements between national and
international organizations, restoration
of mangrove ecosystems, regulation of
extractive activities, and environmental
education since 1988 (ParksWatch
2005b, p. 7). In addition to habitat
protections in place for this species, it
also benefits through conservation
efforts by these NGOs.
´
The World Land Trust and Fundacion
Pro-Bosque are working in the Cerro
Blanco Reserve area with local
communities, focusing on Puerto
Hondo, where young local people, with
guidance and training from Foundation
staff, lead tourists on guided canoe trips
through a rich mangrove estuary
(https://www.wlt.org, accessed June 15,
2011). Between 2006 and 2010 some 235
hectares (581 ac) of degraded lands have
been reforested with over 250,000
saplings of 30 native species. In 2004 an
environment education centre was
constructed for use by the local
community, and a children’s ecology
club runs weekly activities. A
community park warden program is
building local awareness for this unique
reserve and its wildlife. WLT and
´
Fundacion Pro-Bosque are seeking to
expand the Cerro Blanco Reserve
through additional land purchase. This
includes both unprotected and critically
threatened forest habitat near the
existing reserve, as well as land that has
been deforested but can be replanted.
International and local NGOs are also
actively involved in working towards
forest protection. Several reserves have
´
been established. Fundacion Jocotoco,
an Ecuadorian organization established
to protect land for the conservation of
Ecuador’s endangered birds such as the
grey-cheeked parakeet, buys lands and
manages them as private ecological
reserves. Ecotourism activities,
particularly focusing on birding
expeditions, in the Tumbesian region
are abundant. Many of the ecotourism
companies advertise the grey-cheeked
parakeet as an ecotourism draw (Woods
2010, p. 34; Van den Schoor 2007, p. 13;
Elwonger et al. 2004, pp. 3, 20). All of
these efforts are likely to have a
significant positive effect on grey-

cheeked parakeet habitat, particularly in
the absence of the international pet
trade, which was the greatest threat to
the species prior to the 1990s. New
reserves are being created within this
species range (WLT 2011, p. 1), and its
population has increased in at least one
reserve, Buenaventura (WLT 2011, p. 2).
Ecotourism generates income in local
communities, environmental education
programs conducted by NGOs increase
awareness.
These and other NGOs have been
involved in some form of protection of
this species’ habitat for many years and
are likely to be involved in the future.
Although these partnerships and
conservation activities are discretionary
and not regulatory mechanisms; they are
having positive effects on this species
and its habitat by providing data
through scientific research,
environmental education, and
community-based conservation
programs; and they partner with both
the governments of Peru and Ecuador in
carrying out their activities.
The governments of Ecuador and Peru
are also investing in reforestation
efforts. Despite no laws existing in Peru
that require reforestation activities, Peru
is implementing reforestation projects,
in part through carbon credits. Peru
recently implemented its National
Reforestation Plan. One aspect of this
plan is to convert degraded lands back
to natural habitat by planting native
species. Although there is some
indication that there may be insufficient
funds for full implementation (Climate,
Community and Biodiversity Alliance
(CCBA) 2010, p. 7), this type of
reforestation is a priority activity in the
plan, especially in rural areas (National
Reforestation Plan 2005, p. 2). In 2008,
Ecuador also implemented a national
forest conservation plan, called
Programa Socio Bosque, in order to
conserve over 5 million ha (12.4 million
ac) of forest (Conservation International
2008, p. 1).
Reducing Emissions From Deforestation
and Forest Degradation (REDD)
In connection with the National
Reforestation Project, Ecuador and Peru
are working towards reducing emissions
from deforestation and forest
degradation by using a concept of
reducing emissions from deforestation
and forest degradation (termed REDD) to
protect forested areas (CarbonTree.org,
https://www.climate-standards.org;
https://www.un-redd.org/AboutREDD,
accessed May 16, 2011). REDD creates
incentives through carbon credits which
promote reforestation.
The Government of Ecuador
implemented the REDD program
PO 00000
Frm 00022
Fmt 4701
Sfmt 4702
through the Ministry of Environment to
stem the current rate of deforestation in
Ecuador (1.46 percent per year), thereby
reducing deforestation (https://www.unredd.org, accessed June 17, 2011). In
2008, the Socio Bosque Program (PSB)
was launched, providing economic
incentives to land owners such as
indigenous communities, who
voluntarily protect their forests. Goals of
Socio Bosque include decreasing
deforestation and the resulting
production of greenhouse gases, and
preserving native forests and native
ecosystems in part by providing needed
financial resources to people in rural
areas. Though the program is still in its
early stages, its inception implies a
commitment by the Ecuadorian
government to protect its natural
resources, initiate reforestation
programs, and protect habitat for species
such as the grey-cheeked parakeet.
Additionally, in March 2011, the
8,795 ha (21,730 ac) Angostura-Faical
Regional Conservation Area, in the
Tumbes Department, was protected by
presidential decree as a carbon offset
project. This was in cooperation with
the Regional Government of Tumbes
and two nongovernmental
organizations: The Carbon Tree
Conservation Fund, and Nature and
Culture International (NCI). The park,
which is approximately 20 km (12 mi)
north of the TRZ, had been primarily
threatened by an advancing agricultural
frontier and degradation by selective
illegal logging. Approximately 65
percent of Ecuador’s native forests are
owned by indigenous communities
¨
(Palacios 2005 in Hubenthal et al. 2010,
p. 4). Because one aspect is to create
sustainable livelihoods (alternatives to
unsustainable use of forested areas) for
indigenous communities and is within
this species’ range, this project is likely
to have a positive impact on this
species’ habitat.
Summary of Factor A
The grey-cheeked parakeet, although
native to a relatively small area, has
been documented in a wide range of
habitat types such as disturbed humid
forest, evergreen forest, deciduous Ceiba
trichistandra forest and scrub, arid
scrubland, and semi-open agricultural
land (Best et al 1995, p. 243). Land use
changes have the potential to cause
forest fragmentation and studies have
shown that over time that some resident
bird diversity declines within forest
fragments (Turner 1996, p. 202).
However, other studies have indicated
that some species, particularly smaller
species such as the grey-cheeked
parakeet, are able to adapt to habitat
changes (Ibarra-Macias et al. 2011, p.
E:\FR\FM\12OCP5.SGM
12OCP5
jlentini on DSK4TPTVN1PROD with PROPOSALS5
Federal Register / Vol. 76, No. 197 / Wednesday, October 12, 2011 / Proposed Rules
703; Moore et al. 2008, p. 961). Timber
extraction, gravel extraction,
encroachment, honey harvest, roads, or
other forms of deforestation occur in
some areas of grey-cheeked parakeet
range; however, there is no indication
that it is impacting this species at the
population level. The range countries
are working to combat deforestation.
Recent commitments by both countries
to stem deforestation under the REDD
program indicate a continued
commitment to protect forest habitat,
including that utilized by the greycheeked parakeet. Both governments’
economies are fairly strong, which has
a positive correlation with wildlife
conservation (Davies et al. 2006, p.
2130). The protected areas in which this
species occurs both in Peru and Ecuador
offer safeguards from development to
populations of grey-cheeked parakeet in
addition to the species persisting in
altered habitat.
This species is commonly seen
throughout its range, in groups of 12–60
birds (Woods 2010, p. 12; Van den
Schoor 2007, p. 12). Although some of
its habitat may be affected by
deforestation, this species appears not to
be adversely affected and it can persist
in altered habitats (Best et al 1995, p.
243), including urban environments.
This species occurs in several protected
areas. Of these, Cerro Blanco Protection
Forest, Ecuador, and Tumbes Reserved
Zone, Peru, are particularly important,
with recent daily counts of over 50
individuals having been observed. This
species is observed regularly on birding
trips; and it appears to be common
within its range in Ecuador’s protected
reserves. The governments of Ecuador
and Peru are both working on
reforestation initiatives and this is likely
to continue into the future. NGOs are
purchasing and preserving lands. Local
ecotourism companies promote
conservation of the species and its
habitat. They advertise this charismatic
species to draw people to these areas.
Additionally, since the pressure of
poaching for the international pet trade
has been alleviated due to restrictions
put in place in the 1980s and 1990s,
grey-cheeked parakeets are commonly
observed in the wild and populations
appear to be increasing (WLT 2011, pp.
1–2). Though individual grey-cheeked
parakeets may be affected by some of
these activities, there is no evidence to
indicate that the grey-cheeked parakeet
is negatively impacted at the population
level. Therefore, based on the best
available scientific and commercial
information, we find that the present or
threatened destruction, modification, or
curtailment of habitat or range is not a
VerDate Mar<15>2010

Jkt 226001
threat to the grey-cheeked parakeet in
any portion of its range now or in the
future.
B. Overutilization for Commercial,
Recreational, Scientific, or Educational
Purposes
Pet Trade
The grey-cheeked parakeet has always
been a popular pet in part because of its
ability to mimic human voices
(Feigelstock 2009, p. 3). In Peru and
Ecuador, it is common to have a parrot
as a pet (Bergman 2009, p. 2; Williams
and Tobias 1994 in Best et al. 1995, p.
244). Illegal bird trade (the uncontrolled
selling of bird species) is common in
markets and street vendors in both
countries (Bergman 2009, pp. 1–5; Alava
et al. 2007, p. 230; Gonzalez 2003, p.
438; Best et al. 1995, pp. 233–250).
Unlike in the United States and the
European Union, the origin of many pet
birds in Latin America is from the wild,
and the practice of poaching for the
domestic pet trade, while it is less
common, continues in Peru and
˜
Ecuador (Gastanaga et al. 2010, pp. 79–
80; Weston and Memon 2009, pp. 77,
79, 82; Gonzalez 2003, p. 438). Several
studies have investigated the harvesting,
local trade, and conservation of parrots
in northeastern Peru and Ecuador.
Despite the local trade in this species,
discussed below, the primary factor
contributing to its decline was the
massive international trade in this
species, which has been effectively
halted through regulatory mechanisms.
In the early 1970s, Ecuador and Peru
banned the export of wildlife. In the late
1970s, Peru lifted the moratorium
(Fuller et al. 1987 in Best et al. 1995, p.
234). By 1983, Ecuador had restricted
exports of wildlife and Peru had
implemented quotas for wildlife exports
(Fuller et al. 1987, p. 289). However,
even in 1987, this species was found in
markets in Lima, Peru, and sold for $10–
$12 USD each (Plowden 1987 in Best et
al. 1995, p. 244). Between 1984 and
1988 (prior to the enactment of the
WBCA in 1992), approximately 42,000
live grey-cheeked parakeets were
reported to have been imported into the
United States (UNEP–WCMC, accessed
May 3, 2011; Mulliken and Thomsen
1990 in Parker et al. 1995, p. 213). In
1989, the trade decreased, but rose again
in 1990–1991 (Mulliken in litt. 1995 in
Best et al. 1995, p. 245). Best et al.
(1995, p. 246) indicated that trade data
may have been exaggerated by
misdeclaring other parrot species as this
species. In 1993, Peru again
implemented a moratorium on exports
of this species, after a recommendation
PO 00000
Frm 00023
Fmt 4701
Sfmt 4702
63501
by the CITES Animal Committee (Best et
al. 1995, p. 246).
Prior to this species being protected
by various regulatory mechanisms (refer
to Factor D) in the early 1990s, this
species had been heavily traded (Collar
and Juniper 1998, p. 14; Best et al. 1995,
pp. 245). Trade in parrots was extremely
common in the 1980s due to huge
demand from developed countries
(Rosales et al. 2007; Best et al., 1995, pp.
234–235). The UNEP–WCMC Trade
Database reported 96,018 live greycheeked parakeets were imported by
reporting countries between 1981 and
1990 (accessed September 14, 2011).
This is an average of 10,668 birds per
year. Exports of over 5,000 live greycheeked parakeets per shipment
occurred in the 1980s. Between 1981
and 1985 it was the fifth most common
Neotropical psittacine species imported
into the U.S.A (Best et al. 1995, p. 244).
Between 1983 and 1988, it constituted
34 percent of Peru’s parrot trade (p.
244). In 1984, Peru exported in excess
of 20,000 grey-cheeked parakeets; and
the U.S.A. was the principal consumer
(Best et al. 1995, p. 245). Since 2000,
only 12 live grey-cheeked parakeets
were reported to have been in
international trade (UNEP–WCMC
CITES Trade database, accessed May 12,
2011), and only one of those was from
Peru or Ecuador. International trade in
this species, which was the primary
factor impacting the population decline
of this species, is now negligible.
Although poaching still occurs, public
sentiment is changing due to
educational awareness programs in Peru
´
and Ecuador (Fundacion Jocotoco 2011).
In the late 1990s, income from the sale
of young parrots in Peru could yield
between $10 and $30 USD per day,
while other sources of income such as
agriculture and day labor would only
yield $5 per day (Kvist et al. 2001 in Lee
2010, p. 3; Gonzalez 2003, pp. 437–446).
In 1998, in the United States, this
species sold for between $175 and $400
(Marsh 1998, p. 2). Prior to the
implementation of many regulatory
protections that were initiated in the
1990s, an entire brood of parrot chicks
would often be taken from nests and
sold locally (Best et al. 1995, p. 244).
Poaching was occurring in the late
1990s even in areas designated as
˜
protected. A study by Gastanaga et al.
examined nest poaching and illegal
trade of parrots, including the reasons
for poaching, methods, seasons, and
locations where the sale and actual
poaching of parrots occurred. This study
found that this species is still being
˜
poached in the wild (Gastanaga et al.
2011, pp. 79–80), even in protected
areas and despite national protections in
E:\FR\FM\12OCP5.SGM

jlentini on DSK4TPTVN1PROD with PROPOSALS5
63502
Federal Register / Vol. 76, No. 197 / Wednesday, October 12, 2011 / Proposed Rules
place. Although during the study in
2007 and 2008, 385 specimens of greycheeked parakeet were found in 5
markets for sale in Peru, the study also
found that where protections and
enforcement have been implemented,
such as in Cusco, there were no parrots
for sale in markets. This study was over
a 12-month period between 2007 and
2008. In the 20 markets in eight cities
visited, the grey-cheeked parakeet was
found in five of those eight cities; but
significantly, not in Lima. The study
indicated that wildlife markets are well
known, and they believed that they had
identified all the wildlife markets in
˜
seven out of the eight cities (Gastanaga
et al., p. 78). The survey was conducted
over four quarterly periods in these 20
markets in eight cities. This species is
commonly found distributed throughout
its historic range within an area of 9,300
km2 (3,591 mi2). Compared with an
average of 10,668 birds per year, 385
specimens of grey-cheeked parakeet
found in 5 markets for sale in Peru is
minimal.
Poaching has been found to be
significantly lower at protected sites
(Pain et al. 2006, p. 322; Wright et al.
2002, p. 719). For example, Gonzalez
(2003, pp. 437–446) found evidence of
poaching, particularly during nesting
seasons, in the Pacaya-Samiria National
Reserve, a protected area in the Loreto
Department, Peru, during his 1996–1999
study. However, he also found that
poaching decreased during the 1998
harvest season (Gonzalez 2003, p. 444),
which he attributed to increased
numbers of birds confiscated by regional
authorities, which subsequently
discouraged poaching (also see Factor
D). An additional factor is that this
species may be less accessible than
other parrot species, due to its
preference for forested habitat that
consists of complex canopy layers.
In the U.S., this species is no longer
common (Feigelstock 2009, p. 3; Low
2003, p. 2) possibly due to its relatively
short lifespan, the difficulty of breeding
this species in captivity, and
susceptibility of this species in captivity
to a wide range of diseases (see Factor
C). The best available information
indicates that poaching is becoming less
frequent due to involvement by NGOs,
minimal international demand for the
species, and improved enforcement by
˜
authorities (Gastanaga et al. 2011, p. 82;
UNEP–WCMC Trade Database).
Recently, this species has been the focus
of many conservation, public awareness
and ecotourism projects. This species
attracts birders, and it is advertised on
many ecotourism internet sites for
Tumbesian Ecuador and Peru.
Conservation programs, particularly
VerDate Mar<15>2010
19:14 Oct 11, 2011
Jkt 226001
with a focus on endemic bird species,
involve local communities, and many
NGOs conduct local educational
awareness of the species’ value in the
´
wild (Fundacion Jocotoco 2011).
Summary of Factor B
Although overutilization for the pet
trade was a threat to this species in the
past, we have no information indicating
that the grey-cheeked parakeet is
currently being overutilized and we
have no reason to believe the levels of
trade that occurred in the past will
become a threat to the species in the
future. The protections in place are
becoming more effective, and
international trade is now negligible.
This species exists in several protected
habitats, and there is no evidence the
species is decreasing in population
(Woods 2010, p. 34, Elwonger et al.
2004, p. 3; Van den Schoor, 2007). In
some cases it appears to be increasing
(WLT 2011, p. 2). It is observed
regularly in three of Ecuador’s protected
reserves (Jorupe, Buenaventura, and
´
Cerro Blanco Reserve), in El Canclon
Lagoon, and in Peru’s TRZ. We
acknowledge that poaching continues to
occur, but the primary impact to the
species that contributed to its several
population decline, the international pet
trade, essentially no longer exists. The
primary impact to the species, removal
of the wild for the international pet
trade, has been reduced to the point
where it is no longer a threat. Since
2000, only one live grey-cheeked
parakeet was reported to have been
exported from either Peru or Ecuador by
CITES-reporting countries. Poaching
may occur in a limited number of areas,
but to the best of our knowledge, it is
not occurring in all locations where this
species occurs. Additionally,
environmental awareness campaigns by
local NGOs are decreasing the levels of
poaching. Based on the best available
scientific and commercial information,
we find that overutilization for
commercial, recreational, scientific, or
educational purposes is not a threat to
the grey-cheeked parakeet now or in the
future.
C. Disease or Predation
This species is susceptible to many
diseases (Pesaro et al. 2005 pp. 321, 325;
USGS 1999, pp. 93–99; Butcher et al.
1990, p. 1025; Panigrahy et al. 1983, p.
1166). However, most of the available
research addresses captive-held birds
which may have a higher incidence of
disease than wild birds due to their
exposure to sick birds, unsanitary
conditions, improper husbandry
methods, etc. It is not clear how
prevalent disease factors into wild
PO 00000
Frm 00024
Fmt 4701
Sfmt 4702
populations of this species. A
discussion of diseases that are known to
affect this species follows.
Avian polyomavirus (APV) is one of
the most significant viral pathogens of
cage birds (Pesaro et al. 2005, p. 321).
This species is susceptible to APV
infection, which appears in birds up to
approximately 14 weeks of age, after
which infection is asymptomatic. The
mortality peak in some Psittacine
species occurs between 4 and 8 weeks
of age (Pesaro et al. 2005 pp. 321, 325).
Most birds infected with APV are mildly
affected (Gonzalez et al. n. d., p. 2). The
extent to which this disease and others
addressed below occur in wild
populations is unclear, but these
diseases have been found to occur in the
wild (USGS 1999, p. 94). USGS
indicates that disease is more likely to
exist where there are major bird
concentrations. APV is likely to affect
this species more frequently if this
species is exposed to humans through
an increase of activities such as
ecotourism (Factor E) or logging (Factor
A), or other disease vectors such as
cattle.
Avian tuberculosis (also known as
avian mycobacteriosis (Mycobacterium
avium) is known to occur in both wild
and captive-held Brotogeris species
(USGS 1999, p. 96; Butcher et al. 1990,
p. 1025; Rosskopf et al. 1986, p. 219;
Panigrahy et al. 1983, p. 1166). There
are 20 types of M. avium.
Mycobacteriosis is seen fairly frequently
among parakeets and other parrots in
captivity (USGS 1999, Chapter 8, p. 96),
and can cause die-offs in captive flocks.
In captivity, parakeets such as the greycheeked parakeet are likely to be
exposed to mycobacterium; however,
cases of tuberculosis have become less
frequent (Butcher et al. 1990, p. 1023).
Birds are more susceptible if their diet
is inadequate, and if they are subjected
to stressful conditions such as crowded
or unsanitary conditions in cages or
cold temperatures (USGS 1999, p. 95);
fecal exposure is the main route of
transmission. This disease causes
chronic wasting characterized by weight
loss, diarrhea, difficulty breathing, and
tumors of the skin and eyes (Butcher et
al. 1990, p. 1023; USGS 1999, Chapter
8, pp. 93–97). Tumors may also affect
the spleen, liver, lungs, air sacs, skin,
and bone marrow. It is spread through
inhalation, direct contact with infected
birds, and ingestion of contaminated
food or water. Parrots can obtain also
tuberculosis from pigs (USGS 1999, p.
1); however, it is unclear if humans can
transmit M. avium to parakeets (USGS
1999, p. 93). M. avium has been found
to persist outside of a host for over 40
months (USGS 1999, p. 97). It persists
E:\FR\FM\12OCP5.SGM
12OCP5
Federal Register / Vol. 76, No. 197 / Wednesday, October 12, 2011 / Proposed Rules
longest in poultry litter, and can also
occur in wastewater, sewage effluent,
and fertilizers (USGS 1999, p. 97). It is
unclear the extent to which tuberculosis
affects this species in the wild; however
USGS reported in 1999 (p. 96) that
tuberculosis has rarely been found to be
the cause of a major die-off.
Although captive birds may be more
susceptible to diseases in captivity, in
most areas where this species occurs,
the habitat is relatively undisturbed and
exposure to disease is likely minimal.
Variation in spatial distribution affects
patterns of disease. In captivity, this
species may be in close quarters, under
stress, and potentially exposed to
diseases that it does not encounter in its
natural, wild environment. Research has
indicated that populations that exist in
separate, smaller, more isolated patches
slows the dispersal rate and increases
the probability of local extinction of
pathogens (Carlsson-Graner and Thrall
2002, p. 97). This species prefers
forested habitat with complex canopy
layers, in areas that are fairly distant
from human establishments. The
species exists in fairly small groups
with large home ranges. Without clear
evidence that these diseases negatively
affect this species in the wild, we do not
consider diseases discussed above to
occur at a level such that we consider
them to be a threat to the species.

Ectoparasites
We examined whether ectoparasitism
by lice and mites is a threat to this
species. Many mites have evolved
symbiotic relationship with avian
species (Atyeo 1989, p. 101). Not all
bird-mite relationships are parasitic;
some might be benign or beneficial
(Proctor and Owens 2000, pp. 358, 362).
Many mites are nonparasitic scavengers
and use nests or bird feathers as habitat.
Despite the presence of mites found in
nests of this species, there is no
evidence that mites cause mortality or
disease, or that they have a negative
effect on this species (Atyeo 1989, p.
101). We conducted a search of
available information, and there is no
other information indicating that lice
and mites negatively affect the species.
Predation
In 2005, a study of nest competition,
which examined preference of substrate
material, age of nesting cavity, and
depredation of several bird species,
indicated that eggs are heavily predated
in Peru (Brightsmith 2005, entire).
Although this study concluded that
nests are heavily predated in Peru, the
study did not include B. pyrrhoptera.
Predators included birds, marsupials,
termites, monkeys, and rodents
VerDate Mar<15>2010
19:14 Oct 11, 2011
Jkt 226001
(Brightsmith 2005, p. 78). This
researcher found that of 47 nests,
including 23 nests in termitarium
(termite mounds), 12 primary cavity
nests, and 13 secondary cavity nests,
between 4 and 17 percent of the nests
in termitarium were preyed upon, and
77 percent of the secondary nests were
preyed upon (Brightsmith 2005, p. 78).
Secondary nests are previously used
tree cavities, and primary nests are
newly excavated tree cavities. The study
found that newly excavated nests had
lower rates of predation.
Over time, bird species such as the
grey-cheeked parakeet develop
mechanisms in order to counter the
effects of predation. All of the predators
in the study described above are native
to Peru and Ecuador; so a natural
predator-prey balance has likely
developed over time. This species lays
between 4 and 6 eggs, usually 5 eggs.
This behavior may be a mechanism that
has developed in order to combat
pressures such as predation. While
predation may be a source of mortality,
there is no evidence that it is a limiting
factor for population growth for this
species. Another response mechanism
to predation is building nests in new
sites; the research above found that
these nests were less affected by
predation. Although predation occurs
on this species, predation is a normal
ecological interaction in the wild. The
best available information does not
indicate that predation is a threat to the
species.
Ants
There is only one report of ant
predation on Brotogeris species.
Research in Peru found that termateria
inhabited by two other species of
Brotogeris (B. sanctithomae and B.
cyanoptera) were coinhabited by
Dolichoderus ants (Brightsmith 2000, p.
536). In another study, ants (species
unknown) had drilled a hole in an egg
and had consumed the contents
(Brightsmith 2005, p. 76). The 2005
study did not include predation by ants
or termites in its results, but ants and
termites also were found to depredate
nests (Brightsmith 2005, p. 77). At this
time, it is unclear why the study did not
include predation by ants and termites.
It may be that predation by ants and
termites was minimal compared with
the mutualistic benefit of sharing
termateria between ants, termites, and
avian species. Observations suggest that
ants consume the feces of bird species,
thereby keeping the nests clean
(Brightsmith 2000, p. 537). Although it
is unclear which species of ant had
depredated this nest, overall, it appears
that there is a mutualistic relationship
PO 00000
Frm 00025
Fmt 4701
Sfmt 4702
63503
between some species of ants and
Brotogeris parakeets (Brightsmith 2005,
p. 77; Brightsmith 2000, p. 536).
Although ants have the potential of
being a localized threat, the best
available information does not indicate
that this factor affects the species such
that it is a threat to the species
throughout all or a significant part of its
range.
Summary of Factor C
We have no evidence of adverse
impacts to wild-populations of greycheeked parakeet from disease or
predation. Disease and predation are
normal occurrences within wild
populations. With respect to the greycheeked parakeet, there is no indication
that these are occurring to an extent that
they are threats. We conclude, based on
the best available scientific and
commercial information, that neither
disease nor predation is a threat to the
grey-cheeked parakeet in any portion of
its range now or in the future.
D. The Inadequacy of Existing
Regulatory Mechanisms
Each range country manages this
species differently. Within each
country, not only is there a wide
variability in the amount of information
available about the species, but also
about the level of management and
monitoring of the species. Existing
regulatory mechanisms that could have
an effect on potential threats to the greycheeked parakeet include (1) local land
use laws, processes, and ordinances; (2)
Federal laws and regulations; and (3)
international treaties. Because most of
the available information addresses the
grey-cheeked parakeet in protected
reserves, the discussion below focuses
on national laws.
Ecuador
Laws
Ecuador has numerous laws and
regulations pertaining to conservation of
its species, forests, and forestry
management (also refer to Factor B).
These include its Forestry Act
(comprised of Law No. 74 of 1981–
Forest Act and conservation of natural
areas and wildlife (Faolex 1981, pp. 1–
54)—and Law No. 17 of 2004—
Consolidation of the Forest Act and
conservation of natural areas and
wildlife (Faolex 2004, pp. 1–29)); the
Ecuadorian Strategy for Forest
Sustainable Development of 2000
(Estrategia para el Desarrollo Forestal
Sostenible); and Decree 346, which
recognizes that natural forests are highly
vulnerable (ITTO 2006, p. 225). The
Ecuadorian government recognizes
different legal categories of protected

lands. As of 2006, the amount of
protected land (both forested and nonforested) in Ecuador was approximately
4.67 million ha (11.5 million ac) (ITTO
2006, p. 228). Ecuador’s National
System of Protected Areas (Sistema
´
Nacional de Areas Protegidas or SNAP)
is a network of lands held by various
entities including national, privately
owned, and community-owned lands
¨
(Hubenthal et al. 2010, p. 5).
Additionally, the grey-cheeked
parakeet is protected under Ecuadorian
law by Decree No. 3,516 of 2003 as
vulnerable (Unified Text of the
Secondary Legislation of the Ministry of
Environment (EcoLex 2003b, pp. 1–2,
34) (also see discussion under Factor B).
This decree summarizes the laws
governing environmental policy in
Ecuador and mandates that the
country’s biodiversity is protected and
used primarily in a sustainable manner.
Appendix 1 of this Decree lists the
Ecuadorian fauna and flora that are
categorized as critically endangered (En
peligro critico), endangered (En peligro),
or vulnerable (Vulnerable) (EcoLex
2003a, p. 16). The grey-cheeked
parakeet’s status confers protections to
the species under Resolution No. 105 of
2000 and Agreement No. 143 of 2003
(Standards for the control of hunting
seasons and licenses for hunting of
wildlife). Resolution No. 105 and
Agreement No. 143 regulate and
prohibit commercial and sport hunting
of all wild bird species, except those
specifically identified by the Ministry of
the Environment or otherwise permitted
(EcoLex 2003a, p. 1; EcoLex 2000, p. 1).
Under this law, the Ministry of the
Environment does not permit
commercial or sport hunting of the greycheeked parakeet (EcoLex 2003b, p. 17).
Although Ecuador allows hunting, and
removal of this species from the wild by
indigenous people is legal for
subsistence purposes (Bergman 2009;
pp. 1–5), there is no evidence that this
practice occurs at an unsustainable
level.
Protected Areas
There are at least 30 protected areas
throughout the country. These protected
areas include national parks, biological
reserves (one is a marine reserve),
ecological reserves, wildlife production
reserves, wildlife sanctuaries, national
recreational areas, and a bi-national
´
park, El Condor, through the Peace
Agreement signed with Peru
(www.ambiente.gov.ec; www.parks.it,
accessed June 10, 2011). A study in
2001 found that tropical parks have
been surprisingly effective at protecting
ecosystems and species within
boundaries designated as parks or other
VerDate Mar<15>2010
19:14 Oct 11, 2011
Jkt 226001
protected status despite underfunding
and pressures for resources (Bruner et
al. 2001, p. 126). The study found that
protected areas are especially effective
in preventing land clearing. It also
found that in 40 percent of parks, land
that had formerly been under
cultivation and that was incorporated
into park boundaries had recovered.
This subsequently led to an increase in
vegetative cover. The study found that
83 percent of parks were successful at
mitigating encroachment (Bruner et al.
2001, p. 125). The study concluded that
the conditions inside the parks
compared with the surrounding areas
were in significantly better condition
than their surrounding areas (Bruner et
al. 2001, p. 125). A later study
supported this finding; it found that
forests in conservation units were four
times better at protecting against
deforestation than unprotected areas
(Oliveira et al. 2007, p. 1235).
Government Incentives
In the past few years, many advances
have been made in protections for this
species; such as incentives initiated by
the government for communities to
conserve this species. In 2006, some
researchers indicated that despite
official protections in place, there were
few actual effective local protections in
Ecuador (Bonaccorso et al. 2006, p. 61).
NGOs had also expressed concern that
Ecuador was not effectively managing
its wildlife and resources. In 2006, the
International Tropical Timber
Organization considered ecosystem
management and conservation in
Ecuador, including effective
implementation of mechanisms that
would protect grey-cheeked parakeet
habitat, to be lacking (ITTO 2006, p.
229). In 2007, another organization
indicated that the Forestry and Wildlife
Service, Office of the Ecuadorian
Ministry of Environment, was not
adequately implementing conservation
measures for the Manglares Churute
Ecological Reserve (MCER), where this
species was recently observed. The NGO
indicated that the management plan in
MCER had not been fully applied (Alava
et al. 2007, p. 231). However, since that
time, the government of Ecuador has
adopted a national forest plan. In 2008,
Ecuador implemented this forest
conservation plan, called Programa
Socio Bosque (‘‘Forest Partners’’) in
order to conserve over 5 million ha (12.4
million ac) of forest (Conservation
International 2008, p. 1). This program,
which is administered through the
Minister of the Environment, offers
incentives to landowners and
indigenous communities willing to
conserve their forests. Goals are to
PO 00000
Frm 00026
Fmt 4701
Sfmt 4702
reduce carbon emissions by 13.5 million
tons per year and to reduce poverty by
providing additional income to more
than two million people in Ecuador.
This program has the support and
involvement of many NGOs, both local
and international. In the range of this
species, many areas are receiving more
protection now, and this species is
being used as an ecotourism magnet.
Additionally, many NGOS are involved
in land conservation and species
protection in Ecuador (refer to
discussion under factor A), and we
expect these activities to continue into
the future.
Although the governmental
institutions responsible for natural
resource oversight in Ecuador may be
under-resourced and there is a lack of
law enforcement on the ground, the
country is making progress in its
conservation. Ecuador’s Ministry of
Environment’s Socio Bosque subsidy
program has encouraged many large
forest owners to participate in this
program. Many NGOs are actively
involved in conservation programs in
Ecuador, particularly in southern
Ecuador, where this species resides. Ten
percent of all of Ecuador falls under
some form of environmental protection
or special status. As of 2006, 500,000
hectares (1,235,527 ac) are covered by
management plans, and management
plans have been prepared for two other
reserves 13,000 ha (32,125 ac) in size
(ITTO 2006, p. 228). The grey-cheeked
parakeet exists in several protected
´
areas such as El Canclon Lagoon, which
was declared a Ramsar site in 1996, and
is one of the 32 identified wetlands in
Ecuador’s coastal region (Alava et al.
2007, p. 224).
NGOs
As discussed under factor A, many
collaborative and innovative
conservation projects to conserve land
have occurred recently. Several NGOs
such as Birdlife International,
WorldLand Trust, Nature and Culture
International, and local organizations
´
such as Fundacion EcoCiencia, Loro
´
Parque Fundacion, ProNaturaleza, and
´
Fundacion Pro-Bosque, are working to
protect areas in Tumbesian Ecuador.
´
The World Land Trust and Fundacion
Pro-Bosque are working in the Cerro
Blanco Reserve area with local
communities, focusing on Puerto
Hondo, where young local people, with
guidance and training from Foundation
staff, lead tourists on guided canoe trips
through a rich mangrove estuary
(https://www.wlt.org, accessed June 15,
2011). Between 2006 and 2010 some 235
hectares (581 ac) of degraded lands have
been reforested with over 250,000

saplings of 30 native species. In 2004 an
environment education centre was
constructed for use by the local
community, and a children’s ecology
club runs weekly activities. A
community park warden program is
building local awareness for this unique
reserve and its wildlife. WLT and
´
Fundacion Pro-Bosque are seeking to
expand the Cerro Blanco Reserve
through additional land purchase. This
includes both unprotected and critically
threatened forest habitat near the
existing reserve, as well as land that has
been deforested but can be replanted. In
addition to habitat protections in place
for this species, it also benefits through
conservation efforts by these NGOs.
Trade
jlentini on DSK4TPTVN1PROD with PROPOSALS5
Ecuador continues to strengthen its
regulatory mechanisms. The decline in
population numbers of this species
primarily occurred in the 1980s due to
significant trade that occurred of this
species (UNEP–WCMC CITES trade
database, accessed September 14, 2011).
Between 1984 and 1988 (prior to the
enactment of the WBCA in 1992),
approximately 42,000 live grey-cheeked
parakeets were reported to have been
imported into the United States (UNEP–
WCMC, accessed May 3, 2011). The
WBCA effectively halted imports of
wild-origin birds into the United States.
Since 2000, only 12 live grey-cheeked
parakeets were reported to have been in
international trade (UNEP–WCMC,
accessed May 12, 2011); and only one of
those was reported to be from either
Peru or Ecuador. Because of adequate
regulatory mechanisms such as CITES
and the WBCA, both at the domestic
and international level, we believe that
the primary threat to this species,
poaching for the international pet trade,
has been alleviated. In addition,
Ecuador continues to design and
implement new regulatory and
conservation strategies to address issues
such as poaching for the pet trade that
affect this species. Based on the
negligible amount of international trade
(also refer to discussion in Factor B), we
do not find that the international trade
in this species is a threat to the species.
Therefore, the best available information
indicates that regulatory mechanisms
are adequate in Ecuador to protect this
species and its habitat.
Peru
Laws
This species is listed as vulnerable in
Peru under Supreme Decree No. 034–
2004–AG (2004, p. 276,855). This decree
prohibits hunting, take, transport, and
trade of protected species, except as
VerDate Mar<15>2010
19:14 Oct 11, 2011
Jkt 226001
permitted by regulation. Poaching for
the domestic pet trade does occur;
however, poaching does not appear to
occur at a level such that it impacts the
species. Other laws that Peru has
enacted to protect parrot species such as
the grey-cheeked parakeet have
˜
generally been effective (Gastanaga et al.
2011, p. 77), particularly since
enactment of Ley Forestal y de Fauna
Silvestre No 27308. This law regulates
the commercialization of wild species,
and the minimum requirements for their
harvest and their collection and
transportation; and it establishes a
maximum collection quota for each
species from their natural environment
˜
(Gastanaga et al. 2011, p. 77). INRENA
annually sets a quota for certain species,
trade in the grey-cheeked parakeet is not
˜
permitted (Gastanaga et al. 2011, p. 77).
Protected Areas
The Peruvian National Protected Area
System includes several categories of
habitat protection. Habitat may be
designated as any of the following: (1)
Parque Nacional (National Park, an area
managed mainly for ecosystem
conservation and recreation); (2)
Santuario (Sanctuary, for the
preservation of sites of notable natural
or historical importance); (3) Reserva
Nacional (National Reserve, for
sustainable extraction of certain
biological resources); (4) Bosque de
´
Proteccion (Protection Forest, to
safeguard soils and forests, especially
for watershed conservation); (5) Zona
Reservada (Reserved Zone, for
temporary protection while further
study is under way to determine their
importance); (6) Bosque Nacional
(National Forest, to be managed for
utilization); (7) Reserva Comunal
(Communal Reserve, for local area use
and management, with national
oversight); and (8) Cotos de Caza
(Hunting Reserve, for local use and
management, with national oversight)
´
(Rodrıguez and Young 2000, p. 330).
National reserves, national forests,
communal reserves, and hunting
reserves are managed for the sustainable
use of resources (IUCN 1994, p. 2). The
designations of National Parks,
Sanctuaries, and Protection Forests are
established by supreme decree that
supersedes all other legal claim to the
land and, thus, these areas tend to
provide more habitat protection than
unprotected areas.
Progress has been made in
establishing protected areas and
implementing protections where this
species occurs: the TRZ, the Cerros de
Amotape National Park and El Angolo
Game Preserve form the Noroeste
Biosphere Reserve. During the process
PO 00000
Frm 00027
Fmt 4701
Sfmt 4702
63505
of establishing these protected areas,
they were initially described as core
zone, protected zone, and transition
zone. The TRZ essentially encompassed
El Caucho and Campo Verde, the buffer
zone was essentially El Angolo Game
Preserve, and the transition zone was
the adjoining areas. The TRZ has had
protected status since 1957, but it has
always experienced pressures from
timber harvest (ParksWatch 2005, p. 5).
In 1970, a 10-year logging moratorium
was implemented. In Tumbes, sawmills
were closed, but some illegal timber
harvest still occurred in the 1970s,
despite government efforts (ParksWatch
2005, p. 5). There had been reports of
some local Ecuadorians who crossed the
border into the protected zone to hunt,
cut wood, and sometimes establish lots
for agriculture (Walker 2001, p. 2).
However, the involvement of an NGO,
ProNaturaleza, in 1988 increased the
effectiveness of protections in this area.
Their activities have included
promoting local involvement,
establishment of agreements between
national and international
organizations, restoration of mangrove
ecosystems, regulation of extractive
activities, and environmental education
(ParksWatch 2005b, p. 7). The
implementation of these additional
protection measures are likely to also
improve the habitat for the grey-cheeked
parakeet.
Domestic Trade
Most of the parrots in the illegal trade
come from the wild, where they have
been harvested by small local
communities and traded to other people
who transport them to wildlife markets
in major cities (Rosales et al. 2007 in
˜
Gastanaga et al. 2011, p. 77; Gonzales
2003, p. 438). Despite the illegal sale of
this species in some Peruvian markets,
efforts to curtail poaching and sale seem
to be improving (note that Gonzales’s
study was conducted between 1996 and
1999). In 2007 and 2008, 385 greycheeked parakeets were found in five of
the eight markets surveyed. The survey
was conducted over four quarterly
periods in these 20 markets in eight
cities. However, in cities such as Cusco
and Puerto Madonado, where INRENA
and the ecological police have increased
enforcement of wildlife protection laws,
there were no grey-cheeked parakeets or
˜
other parrots found for sale (Gastanaga
et al. 2011, p. 82). The illegal parrot
trade has decreased in these areas;
indicating that when enforcement is in
place, protections are effective.
International Wildlife Trade
Removal of this species from the wild
for the pet trade had the greatest impact

63506
Federal Register / Vol. 76, No. 197 / Wednesday, October 12, 2011 / Proposed Rules
jlentini on DSK4TPTVN1PROD with PROPOSALS5
on this species. In 1981, the greycheeked parakeet was listed in
Appendix II of CITES, and in 1992, this
species was protected by the WBCA.
The WBCA effectively shut down
imports of this species into the United
States; one of the largest importers of
this species. CITES requires CITES
Parties to have in place adequate
legislation for its implementation.
Through Resolution Conf. 8.4 (Rev.
CoP15), the Parties to CITES adopted a
process, termed the National Legislation
Project, to evaluate whether Parties have
adequate domestic legislation to
successfully implement the Treaty
(CITES 2010b, pp. 1–5). In reviewing a
country’s national legislation, the CITES
Secretariat evaluates factors such as
whether a Party’s domestic laws
designate the responsible Scientific and
Management Authorities, prohibit trade
contrary to the requirements of the
Convention, have penalty provisions in
place for illegal trade, and provide for
seizure of specimens that are illegally
traded or possessed. The Government of
Peru was determined to be in Category
1, which means they meet all the
requirements to implement CITES.
Ecuador was determined to be in
Category 2, with a draft plan, but not
enacted (https://www.cites.org, SC59
Document 11, Annex p. 1). The
international legal trade in this species
has substantially decreased and is now
negligible. As discussed under factor B,
between 2000 and 2009, only 12 live
specimens were reported in
international trade (UNEP–WCMC); and
only one was from a range country
(Peru). With respect to international
trade, the implementation of the WBCA
and CITES, and the Governments of
Peru and Ecuador have effectively
controlled international trade of this
species. Based on the best available
information, the Governments of
Ecuador and Peru are adequately
enforcing their respective legal
frameworks. Based on the decrease in
reported trade, we believe that
international trade has been adequately
curtailed by regulatory mechanisms.
Summary of Factor D
We considered the adequacy of
existing regulatory mechanisms to
protect the grey-cheeked parakeet. Peru
and Ecuador have enacted numerous
laws and regulatory mechanisms to
protect and manage wildlife and their
habitats. Studies by the Peruvian
Society for Environmental Law (SPDA)
concluded that there are approximately
5,000 laws and regulations directly or
indirectly related to environmental
protection and natural resource
conservation in Peru. In 2001, Muller
VerDate Mar<15>2010
19:14 Oct 11, 2011
Jkt 226001
(2001, pp. 1–2) indicated that many of
these are not effective due to limited
implementation and/or enforcement
capability. However, one of the most
significant threats to the species prior to
the 1990s was the international pet
trade, but this trade has been negligible
since 2000. Both Ecuador and Peru’s
economies are improving, and both
countries are implementing many
projects and mechanisms that are
having a positive impact on this species
and its habitat.
The grey-cheeked parakeet is listed as
‘‘vulnerable’’ under both Ecuadorian
and Peruvian law. It occurs within at
least four protected areas in Peru and
Ecuador. This species is commonly
observed in both Ecuador and Peru in
protected areas; and flocks of this
species are frequently observed. Some
habitat degradation continues, including
within protected areas (see factor A).
However, we find that the existing
regulatory mechanisms are adequate to
mitigate these activities throughout the
grey-cheeked parakeet’s range. The most
significant threat, poaching for the
international pet bird trade, has
declined significantly, and the
population has had time to recover.
There is no indication that the
population is currently declining; it
appears to be thriving in protected areas
based on numerous recent birding
expeditions. The international pet trade
that contributed to the species’ past
decline, is now negligible.
Other factors that influenced our
decision are that these governments are
both implementing reforestation efforts
(see factor A) and forest conservation
programs. Lands are being purchased
and are converted to reserves.
Ecotourism such as birding trips in
these reserves, which in part provides
funding, appears to be prevalent in the
Tumbesian region. Although some
limited poaching may continue to occur,
there is no evidence to suggest that they
are having significant population level
effects. This species exists in several
protected habitats and is commonly
observed throughout its range. There is
no evidence that its population is still
declining (WLT 2011, p. 2; Woods 2010,
p. 34, Elwonger et al. 2004, p. 3; Van
den Schoor, 2007). It is observed
regularly in three of Ecuador’s protected
reserves (Jorupe, Buenaventura, and
Cerro Blanco Reserve), it was observed
´
in El Canclon Lagoon (Alava et al. 2007)
and in Campo Verde in 2006; and in
Peru’s TRZ. The grey-cheeked parakeet
is also protected under CITES and the
WBCA, which we find have been
effective in mitigating the impact to this
species from international trade.
Because there have been so few
PO 00000
Frm 00028
Fmt 4701
Sfmt 4702
individual live grey-cheeked parakeets
in trade since 2000, we believe that
international trade controlled via valid
CITES permits is not a threat to the
species. Based on the best available
scientific and commercial information,
we find that inadequate mechanisms are
not a threat to the grey-cheeked parakeet
in any portion of its range now or in the
future.
E. Other Natural or Manmade Factors
Affecting Its Continued Existence
˜
El Nino Events
The arid terrestrial ecosystem of
northwest Peru, where the grey-cheeked
parakeet occurs, is influenced by El
˜
Nino events (Rodriguez et al. 2005, p.
1), which has the potential to have
profound and long-lasting effects
(Mooers et al. 2007, p. 2; Holmgren et
˜
al. 2006a, p. 87). An El Nino weather
phenomenon in 1982–1983, caused
widespread flooding in some parts of
the country and severe droughts in
others (https://www.state.gov/r/pa/ei/
bgn/35762.htm, accessed May 5, 2011).
˜
El Nino–southern oscillation (ENSO)
cycles increase the risk of fire because
these events are often followed by years
of extremely dry weather (Block and
Richter 2007, p. 1). Accumulated
biomass dries and adds to the fuel load
in the dry season (Power et al. 2007, p.
898; Block and Richter 2007, p. 1).
Evidence suggests that the fire cycle in
Peru has shortened, particularly in
coastal Peru and west of the Andes
(Power et al. 2007, pp. 897–898), which
could have broad ecological
consequences (Block and Richter 2007,
p. 1; Power et al. 2007, p. 898), and
ENSO cycles have increased in
periodicity and severity (Richter 2005,
pp. 24–25). However, research suggests
that ENSO events can also have positive
rather than negative effects. The amount
˜
of rainfall during an El Nino year can be
more than 25 times greater than during
normal years in northern Peru
(Holmgren et al. 2006a, p. 90; Rodriguez
˜
et al. 2005, p. 2). El Nino events are
important triggers for regeneration of
plants in semiarid ecosystems,
particularly in the dry forest of
northwest Peru (Holmgren et al. 2006a,
p. 88; Lopez et al. 2006, p. 903;
´
Rodrıguez et al. 2005, pp. 2–3). During
˜
El Nino events, plant communities and
barren lands are transformed into lush
vegetation, as seeds germinate and grow
more quickly in response to increased
rainfall (Holmgren et al. 2006a, p. 88;
Holmgren et al. 2006b, pp. 2–8;
´
Rodrıguez et al. 2005, pp. 1–6). This
species is a food generalist and exists in
a climate zone that is fairly stable (it is
in a narrow latitudinal band). Thus, we
E:\FR\FM\12OCP5.SGM
12OCP5
Federal Register / Vol. 76, No. 197 / Wednesday, October 12, 2011 / Proposed Rules
find that the grey-cheeked parakeet is
likely to be less affected by ecosystem
˜
changes due to El Nino events than
other species.
jlentini on DSK4TPTVN1PROD with PROPOSALS5
Tourism
Tourism can have both positive and
negative aspects. One form of tourism,
ecotourism, has the potential to have a
positive effect by providing economic
incentives for communities to protect
their natural areas. This in turn makes
them less reliant on the resources
within a protected area, and encourages
sustainable practices. In many cases,
local communities may contribute to the
habitat degradation or remove the
species from the wild. Ecotourism
projects, by creating alternative sources
of income, can be a way to create
awareness of a species’ plight, and also
can attract conservation funding to an
area. Community conservation projects
have demonstrated that if local
communities understand the benefit of
conserving the resource and are
provided alternative sources of income,
they have incentive to protect the
resource rather than overutilize the
resource (Lee 2010, p. 13). There is
increasing awareness to minimize
environmental impacts of visitors.
Ecotourism is being conducted in a
manner that is not disturbing to the
species. As of 2005, TRZ was attracting
500 tourists annually, and the tourists
generally only visited particular areas
(ParksWatch 2005b, p. 11). Based on the
positive effects of low-impact
ecotourism, and also the potential
positive effects of ecotourism, we do not
find that tourism has a significant
impact on the species.
Summary of Factor E
We evaluated other natural or
manmade factors that might affect the
continued existence of the grey-cheeked
˜
parakeet. Neither El Nino events nor
tourism were found to be threats to the
species. The grey-cheeked parakeet
exists in protected areas in both Ecuador
and Peru that provide suitable habitat.
Lowland bird species such as the grey˜
cheeked parakeet are adapted to El Nino
events, and this climate zone is fairly
stable in its weather patterns. Tourism
occurs at low levels, and the tourism is
likely very minimal in protected areas
where this species exists. Based on the
best available scientific and commercial
information, we find that other natural
or manmade factors are not a threat to
the grey-cheeked parakeet in any
portion of its range now or in the future.
Finding
As required by the Act, we considered
the five factors in assessing whether the
VerDate Mar<15>2010
19:14 Oct 11, 2011
Jkt 226001
grey-cheeked parakeet is threatened or
endangered throughout all of its range.
Section 3 of the Act defines an
‘‘endangered species’’ as ‘‘any species
which is in danger of extinction
throughout all or a significant portion of
its range’’ and a ‘‘threatened species’’ as
‘‘any species which is likely to become
an endangered species within the
foreseeable future throughout all or a
significant portion of its range.’’
We examined the best scientific and
commercial information available
regarding the past, present, and future
threats faced by the grey-cheeked
parakeet. We reviewed the petition,
information available in our files, and
other available published and
unpublished information, and we
consulted with experts. We believe the
species does not warrant listing for the
following reasons. There are no
indications that the population of this
species is currently declining. Both
IUCN and BLI’s population trend
justification are from population studies
conducted prior to 1995; and the
categorization was primarily based on
rapid rates of population decline caused
by past trapping for the international pet
trade. The EU ban and the
implementation of the WBCA effectively
halted the international trade in this
species. International trade, which was
the primary reason for its decline prior
to the 1990s, is now negligible. Further,
both Peru and Ecuador, the range
countries for this species, categorize this
species as vulnerable.
Additionally there has been
significant NGO involvement in the
protection of endemic bird areas in the
range of grey-cheeked parakeet. The
World Land Trust (WLT) indicated that
in a recently purchased area near the
Buenaventura Reserve, the grey-cheeked
parakeet has increased locally, but did
not give specific population estimates
(WLT 2011, pp. 1–2). Habitat loss is
often a threat to wildlife; however, in
this case, both Peru and Ecuador are
implementing reforestation programs,
and this species exists in several
protected areas, as well as areas outside
of protected areas. The species appears
to adapt to altered habitat (Best et al.
1995, p. 233). Several birding surveys
have focused on the Tumbesian biome,
which extends 130,000 km (80,778 mi)
into southern Ecuador and northern
Peru. Surveys in the early 2000s to
determine biodiversity in the Loja
Province observed this species fairly
regularly in forested areas. The
Tumbesian area still has primary and
secondary forested areas that are
protected—in Ecuador, this species
exists in MCER, Jorupe Reserve,
Buenaventura Reserve, and Cerro
PO 00000
Frm 00029
Fmt 4701
Sfmt 4702
63507
Blanco Reserve, and in Peru, the species
exists in Tumbes Reserved Zone (TRZ),
specifically at El Caucho and Quebrada
Faical.
Habitat loss and degradation (Factor
A) and poaching (Factor B) still occur in
Peru and Ecuador. We acknowledge that
these activities affect individuals, but
there is no evidence that they are having
significant impacts such that they are
threats to the species. We find that these
activities are not of sufficient
imminence, intensity, or magnitude to
indicate that the grey-cheeked parakeet
is in danger of extinction (endangered)
or likely to become endangered within
the foreseeable future (threatened),
throughout its range. The distribution of
its population in many reserves in
Ecuador and Peru helps contribute to
the viability of the species overall; and
its distribution is providing a margin of
safety for the species to withstand
catastrophic events, strengthening the
redundancy of the species. This species
exists in protected habitat in both
countries, and legal international trade,
formerly the most significant threat to
this species, has been very limited since
international trade has been regulated.
Illegal domestic trade (Factor B), while
occurring in some areas, is not having
a significant impact such that it is a
threat. Disease and predation (Factor C)
are not impacting this species such that
they are threats. Additionally, the
involvement of NGOs in protecting
more of this species’ habitat is likely to
positively impact the species. Based on
the lack of threats to the grey-cheeked
parakeet throughout its range, as
described above, we determine that the
grey-cheeked parakeet is not in danger
of extinction or likely to become so
within the foreseeable future. Therefore,
we find that listing the grey-cheeked
parakeet as a threatened or endangered
species is not warranted.
We request that you submit any new
information concerning the status of, or
threats to, the grey-cheeked parakeet or
its habitat to our Branch of Foreign
Species (see ADDRESSES) whenever it
becomes available. New information
will help us monitor this species and
encourage its conservation.
Significant Portion of the Range
Having determined that the greycheeked parakeet is not in danger of
extinction or likely to become so within
the foreseeable future throughout all of
its range, we must next consider
whether there are any significant
portions of the range where the greycheeked parakeet is in danger of
extinction or is likely to become
endangered in the foreseeable future.

Federal Register / Vol. 76, No. 197 / Wednesday, October 12, 2011 / Proposed Rules
jlentini on DSK4TPTVN1PROD with PROPOSALS5
The Act defines an endangered
species as one ‘‘in danger of extinction
throughout all or a significant portion of
its range,’’ and a threatened species as
one ‘‘likely to become an endangered
species within the foreseeable future
throughout all or a significant portion of
its range.’’ The term ‘‘significant portion
of its range’’ is not defined by the
statute. For the purposes of this finding,
a portion of a species’ range is
‘‘significant’’ if it is part of the current
range of the species and it provides a
crucial contribution to the
representation, resiliency, or
redundancy of the species. For the
contribution to be crucial it must be at
a level such that, without that portion,
the species would be in danger of
extinction or likely to become so in the
foreseeable future.
In determining whether a species is
threatened or endangered in a
significant portion of its range, we first
identify any portions of the range of the
species that warrant further
consideration. The range of a species
can theoretically be divided into
portions in an infinite number of ways.
However, there is no purpose to
analyzing portions of the range that are
not reasonably likely to be significant
and threatened or endangered. To
identify only those portions that warrant
further consideration, we determine
whether there is substantial information
indicating that: (1) The portions may be
significant, and (2) the species may be
in danger of extinction there or likely to
become so within the foreseeable future.
In practice, a key part of this analysis is
whether the threats are geographically
concentrated in some way. If the threats
to the species are essentially uniform
throughout its range, no portion is likely
to warrant further consideration.
Moreover, if any concentration of
threats applies only to portions of the
species’ range that clearly would not
VerDate Mar<15>2010
19:14 Oct 11, 2011
Jkt 226001
meet the biologically based definition of
‘‘significant’’ (i.e., the loss of that
portion clearly would not reasonably be
expected to increase the vulnerability to
extinction of the entire species to the
point that the species would then be in
danger of extinction or likely to become
endangered in the foreseeable future),
such portions will not warrant further
consideration.
If we identify portions that warrant
further consideration, we then
determine their status (i.e., whether in
fact the species is endangered or
threatened in a significant portion of its
range). Depending on the biology of the
species, its range, and the threats it
faces, it might be more efficient for us
to address either the ‘‘significant’’
question first, or the status question
first. Thus, if we determine that a
portion of the range is not ‘‘significant,’’
we do not need to determine whether
the species is endangered or threatened
there; if we determine that the species
is not endangered or threatened in a
portion of its range, we do not need to
determine if that portion is
‘‘significant.’’
Applying the process described above
for determining whether a species is
threatened in a significant portion of its
range, we considered status first to
determine if any threats or potential
threats acting individually or
collectively threaten or endanger the
species in a portion of its range. We find
that the potential threats evaluated are
not of sufficient imminence, intensity,
or magnitude to indicate that the greycheeked parakeet is in danger of
extinction (endangered), or likely to
become endangered within the
foreseeable future (threatened),
throughout all of its range. Therefore,
we find that listing the grey-cheeked
parakeet as a threatened or endangered
species is not warranted throughout all
of its range.

Conclusion of 12-Month Finding
We do not find that the grey-cheeked
parakeet is in danger of extinction now,
nor is it likely to become endangered
within the foreseeable future,
throughout all or a significant portion of
its range. Therefore, listing the species
as endangered or threatened under the
Act is not warranted at this time. We
request that you submit any new
information concerning the status of, or
threats to, the grey-cheeked parakeet to
our Endangered Species Program,
Branch of Foreign Species (see
ADDRESSES) whenever it becomes
available. New information will help us
monitor this species and encourage its
conservation. If an emergency situation
develops for the grey-cheeked parakeet
or any other species, we will act to
provide immediate protection.

SUMMARY: We, the U.S. Fish and Wildlife Service, announce a status
review (12-month finding) on a petition to list the blue-headed macaw
(Primolius couloni) and grey-cheeked parakeet (Brotogeris pyrrhoptera)
as threatened or endangered under the Endangered Species Act of 1973,
as amended (Act). After review of all available scientific and
commercial information, we find that listing the blue-headed macaw or
grey-cheeked parakeet is not warranted at this time. However, we ask
the public to submit to us any new information that becomes available
concerning the threats to these species or their habitat at any time.
DATES: The finding announced in this document was made on October 12,
2011.
ADDRESSES: This finding is available on the Internet at https://www.regulations.gov at Docket Number FWS-R9-ES-2011-0071. Supporting

SUPPLEMENTARY INFORMATION:
Background
Section 4(b)(3)(B) of the Endangered Species Act (Act) (16 U.S.C.
1531 et seq.) requires that, for any petition to revise the Federal
Lists of Endangered and Threatened Wildlife and Plants that contains
substantial scientific or commercial information that listing the
species may be warranted, we make a finding within 12 months of the
date of receipt of the petition. In this finding, we determine whether
the petitioned action is: (a) Not warranted, (b) warranted, or (c)
warranted, but immediate proposal of a regulation implementing the
petitioned action is precluded by other pending proposals to determine
whether species are threatened or endangered, and expeditious progress
is being made to add or remove qualified species from the Federal Lists
of Endangered and Threatened Wildlife and Plants. Section 4(b)(3)(C) of
the Act requires that we treat a petition for which the requested
action is found to be warranted but precluded as though resubmitted on
the date of such finding, that is, requiring a subsequent finding to be
made within 12 months. We must publish these 12-month findings in the
Federal Register.
Previous Federal Actions
Petition History
On January 31, 2008, the Service received a petition dated January
29, 2008, from Friends of Animals, as represented by the Environmental
Law Clinic, University of Denver, Sturm College of Law, requesting we
list 14 parrot species under the Act. The petition clearly identified
itself as a petition and included the requisite information required in
the Code of Federal Regulations (50 CFR 424.14(a)). On July 14, 2009
(74 FR 33957), we published a 90-day finding in which we determined
that the petition presented substantial scientific and commercial
information to indicate that listing may be warranted for 12 of the 14
parrot species.
In our 90-day finding on this petition, we announced the initiation
of a status review under the Act to list as threatened or endangered
the following 12 parrot species:
Blue-headed macaw (Primolius couloni)
Crimson shining parrot (Prosopeia splendens)
Great green macaw (Ara ambiguus)
Grey-cheeked parakeet (Brotogeris pyrrhoptera)
Hyacinth macaw (Anodorhynchus hyacinthinus)
Military macaw (Ara militaris)
Philippine cockatoo (Cacatua haematuropygia)
Red-crowned parrot (Amazona viridigenalis)
Scarlet macaw (Ara macao)
White cockatoo (C. alba)
Yellow-billed parrot (Amazona collaria)
Yellow-crested cockatoo (C. sulphurea)
We initiated this status review to determine if listing each of the
12 species is warranted, and opened a 60-day period to allow all
interested parties an opportunity to provide comments and information
on the status of these 12 species. The public comment period closed on
September 14, 2009.
On July 21, 2010, a settlement agreement was approved by the Court
(CV-10-357, D. D.C.) in which the Service agreed to submit to the
Federal Register by July 29, 2011; September 30, 2011; and November 30,
2011, respectively, determinations on whether the petitioned action is
warranted, not warranted, or warranted but precluded by other listing
actions for no fewer than four of the petitioned species. On August 9,
2011, the Service published in the Federal Register a 12-month status
review and proposed rule for the following four parrot species: Crimson
shining parrot, Philippine cockatoo, white cockatoo, and yellow-crested
cockatoo (76 FR 49202).
Current Action
In this status review, we make a determination whether the
petitioned action is warranted, not warranted, or warranted but
precluded by other listing actions for the blue-headed macaw and grey-
cheeked parakeet. This Federal Register document complies, in part,
with the second deadline in the court-approved settlement agreement
mentioned above.
Species Information and Factors Affecting the Species
Section 4 of the Act (16 U.S.C. 1533) and implementing regulations
(50 CFR part 424) set forth procedures for adding species to, removing
species from, or reclassifying species on the Federal Lists of
Endangered and Threatened Wildlife and Plants. Under section 4(a)(1) of
the Act, a species may be determined to be endangered or threatened
based on any of the following five factors:
(A) The present or threatened destruction, modification, or
curtailment of its habitat or range;
(B) Overutilization for commercial, recreational, scientific, or
educational purposes;
(C) Disease or predation;
(D) The inadequacy of existing regulatory mechanisms; or
(E) Other natural or manmade factors affecting its continued
existence.
In considering whether a species may warrant listing under any of
the five factors, we look beyond the species' exposure to a potential
threat or aggregation of threats under any of the factors, and evaluate
whether the species responds to those potential threats in a way that
causes actual
[[Page 63481]]
impact to the species. The identification of threats that might impact
a species negatively may not be sufficient to compel a finding that the
species warrants listing. The information must include evidence
indicating that the threats are operative and, either singly or in
aggregation, affect the status of the species. Threats are significant
if they drive, or contribute to, the risk of extinction of the species,
such that the species warrants listing as endangered or threatened, as
those terms are defined in the Act.
Below is a species-by-species description and analysis of the five
factors. The species are considered in alphabetical order, beginning
with the blue-headed macaw, followed by the grey-cheeked parakeet.
I. Blue-Headed Macaw (Primolius couloni)
Species Description
The blue-headed macaw is a small species of macaw belonging to the
family Psittacidae, the parrot family. It measures approximately 41
centimeters (cm) (16 inches (in)) in length. Average male and female
wing length measures approximately 226 millimeters (mm) (8.9 in) and
220 mm (8.6 in), respectively. Average tail lengths for males and
females measure 223 mm (8.7 in) and 204 mm (8.0 in), respectively
(Forshaw 1973, p. 386). There is little sexual dimorphism between males
and females (Lee 2010, p. 5). Adults are characterized by green general
plumage with slightly more yellowish underparts. The entire head,
except for the grey bare facial area, is blue. Primaries and primary-
coverts (wing feathers) are blue and secondaries and outermost upper
wing-coverts are blue edged with green. The upperside of the tail is
blue, whereas the undersides of flight and tail feathers are a dusky
yellow. The bill is grey-black, which becomes horn-colored on the
culmen (the upper ridge of the bill) and at the tip of the upper
mandible. The iris is yellow, and legs are flesh-pink. Immature blue-
headed macaws have not been described (Forshaw 1973, p. 386).
The blue-headed macaw occurs mainly in eastern Peru, in the
departments of Loreto, Hu[aacute]nuco, Pasco, Ucayali, Cusco, Madre de
Dios, Ayacucho, Puno, and Jun[iacute]n; but it also occurs just inside
the border of extreme western Brazil, in the States of Acre and
Rond[ocirc]nia, and just inside the border of northern Bolivia, in the
departments Pando, Beni, and La Paz (BirdLife International (BLI)
2011a, unpaginated; Tobias and Brightsmith 2007b, pp. 1-6). It has been
recorded from 61 localities, with no significant association with
forest type, riverine habitats, degree of disturbance, or altitude.
Records of the blue-headed macaw occur in both foothill regions and
lowlands ranging in elevation from 200 meters (m) (656 feet (ft)) to
1,500 m (4,921 ft), and in a wide range of habitats, including terra
firme forests (forests not inundated by flood waters), mature
floodplain forests, successional river edge forests, and Mauritia palm
swamps. One study found that this species was slightly more common in
degraded areas than in pristine forests (Brightsmith 2009, personal
communication (pers. comm.); Tobias and Brightsmith 2007, pp. 126, 129-
130).
The estimated total global range for this species is 609,494 square
kilometers (km\2\) (235,326 square miles (mi\2\)) and spans large areas
of remote and unexplored terrain. The extent of occurrence (the global
range, excluding disjunctions and major areas of inappropriate habitat)
has been calculated as 460,000 km\2\ (177,606 mi\2\), an area larger
than previously thought (Brightsmith 2009, pers. comm.; Tobias and
Brightsmith 2007, pp. 126, 129, 133). However, the extent of occurrence
may be underestimated, as data is lacking from Brazil, the global range
is more than 90 percent forested, and data suggest anthropogenic
pressures have not eliminated this species from any large areas (Tobias
and Brightsmith 2007, p. 129). Brightsmith (2009, pers. comm.) notes
that the blue-headed macaw is not absent from any portion of its
historical range.
In 1990, Lambert et al. (2003, as cited in Tobias and Brightsmith
2007, p. 127) estimated the global population of blue-headed macaws to
be 10,000 individuals. In 2003, Gilardi estimated the global population
to be well under 1,000 mature individuals; BLI revised the global
estimate to 1,000-2,499 mature individuals in 2005 (Tobias and
Brightsmith 2007, p. 127). It is unclear why population estimates have
varied, but may be due to few published sources, anecdotal accounts,
poor data quality (Tobias and Brightsmith 2007, p. 127), or differences
in methodology. The most recent data suggest that this species occurs
at a conservative density of one mature individual per 10-50 km\2\
(3.0-19.3 mi\2\); using the calculated 460,000 km\2\ extent of
occurrence, Tobias and Brightsmith (2007, p. 126) estimate the
population to be 9,200-46,000 mature individuals and 11,500-57,500
individuals if immature birds are included (Tobias and Brightsmith
2007, p. 133). Most of the 61 localities where this species has been
recorded are easily accessible by road or river, potentially causing a
bias towards areas affected by trapping and underestimating abundance.
Furthermore, much of the global range has yet to be surveyed (Tobias
and Brightsmith 2007, pp. 132-133).
BLI (2011a, unpaginated), based on Tobias and Brightsmith (2007,
pp. 126-138), reports that the population is declining at a slow-to-
moderate and ongoing pace. However, Brightsmith (2009, pers. comm.)
notes that this conclusion is not based on real evidence from wild
populations. In fact, Tobias and Brightsmith (2007, p. 134) and
Brightsmith (2009, pers. comm.) note that based on sightings data,
there is no evidence of a decline in range or numbers of blue-headed
macaws in the wild and that the possibility that the blue-headed macaw
is increasing with the spread of degraded forests along rivers cannot
be discounted (Tobias and Brightsmith 2007, pp. 132-133). Hennessey
(2011, per. comm.) also notes that populations in Peru and Bolivia have
remained healthy. There is no place within its range where this species
has been searched intensively and does not occur (Brightsmith 2009,
pers. comm.). At the Tambopata Research Center, blue-headed macaws have
been steadily increasing since the year 2000 (Brightsmith 2009, pers.
comm.). Sightings of the blue-headed macaw in Peru have also increased
in the past 10 years (Brightsmith 2009, pers. comm.). Additionally, the
lowlands of southeastern Peru, the core of the species' range, are the
home of a wide variety of international research stations; parrot
populations are monitored annually, so if the blue-headed macaw begins
to decline, the research community would note this and begin specific
protection and recovery actions (Brightsmith 2009, pers. comm.).
The diet of the blue-headed macaw has not been observed; however,
parrots generally feed on seeds, ripe and unripe fruit, and flowers,
but may also utilize other plant parts, such as nectar, leaves, and
bark (Lee 2010, p. 6; Brightsmith 2006, p. 2; Cowen no date (n.d.), pp.
5, 17). Cowen (n.d., p. 16) found that a psittacine community, which
included the blue-headed macaw, mainly fed on three tree species:
Ochroma pyramidale (balsa), Euterpe precatoria (a species of palm), and
Cecropia peltata (trumpet tree). This species may undergo some form of
nomadism to track food across the landscape (Tobias and Brightsmith
2007, p. 132). Parrots may travel a few kilometers to hundreds of
kilometers in search of food resources (Lee 2010, p. 8). Because
parrots feed primarily on fruits and flowers, they are linked to the
[[Page 63482]]
fruiting and flowering patterns of trees; fluctuations in abundance and
availability of these food sources may change diets, result in
movements to areas with greater food availability, and influence local
seasonal patterns of bird abundance (BLI 2011a, unpaginated; Lee 2010,
p. 7; Tobias and Brightsmith 2007, p. 132; Brightsmith 2006, p. 2;
Renton 2002, p. 17; Cowen n.d., pp. 5, 23). In some locations within
its range, the blue-headed macaw is not considered uncommon and is
recorded throughout the year, but appears scarce in others or varies
seasonally in response to food availability (BLI 2011a, unpaginated).
Geophagy, the intentional consumption of soil, is known for parrots
(Brightsmith 2004a, p. 534). In South America, parrots, including the
blue-headed macaw, gather at riverbanks to consume soil; these sites
are referred to as ``clay licks'' (Brightsmith 2004c, pp. 134, 137;
Brightsmith 2004b, p. 5; Brightsmith 2004a, p. 535). Clay lick usage by
blue-headed macaws is regular at several sites, and occurs year-round
at Tambopata, Peru (Tobias and Brightsmith 2007, p. 131). There have
been many theories proposed to explain why birds consume soil,
including mineral supplementation, mechanical aid to digestion, pH
buffering, treatment for endoparasites, and adsorption of dietary
toxins (Brightsmith 2004c, p. 143; Brightsmith 2004b, p. 1; Brightsmith
2004a, p. 534-535). The reasons for soil selection may vary, with sites
depending on the needs of the birds and the characteristics of the
soils present (Brightsmith 2004a, p. 542). Research in Peru has shown
that parrots consume soil to obtain sodium (mineral supplementation)
and assist in the adsorption of dietary toxins (Brightsmith 2004c, p.
134; Brightsmith 2004b, pp. 3-4; Brightsmith 2004a, pp. 541-542).
Furthermore, research conducted at the Tambopata Research Center in
Peru found that local clay lick use by parrots varied seasonally, with
low use occurring at a time when parrots appear to leave the area due
to low fruit availability and peaks occurring during the breeding
season (Brightsmith 2004b, p. 3). Peak clay lick use coincided with the
breeding season when adults feed clay to young chicks during the period
of maximum growth and least resistance to natural toxins found in their
diet (Brightsmith 2004b, p. 4).
The blue-headed macaw is reported to occur in pairs or groups of
three. However, groups of 4 or more are routinely reported throughout
the range, groups of 10 or more have been reported from 13 localities,
and 2 groups were reported to have 53 and 60 individuals, respectively
(Tobias and Brightsmith 2007, p. 131-132). Few courtship displays have
been described for parrots, but are assumed to be simple and include
actions such as bowing, wing-drooping, wing-flicking, tail-wagging, and
foot raising (Austin 1961, p. 33). Most parrot species are monogamous
and remain paired for long periods of time, even for life. The age at
which parrots reach sexual maturity varies but, in general, is between
3 and 4 years in larger species and 1 to 2 years in smaller species
(Austin 1961, p. 32). In captivity, the age in which the species is
able to breed ranges from 2.5 to 5 years (Tobias and Brightsmith 2007,
p. 132). The nesting season of the blue-headed macaw is not known, but
for other species of parrots and macaws found at the same site, the
nesting season runs from June to November and November to March,
respectively (Brightsmith 2006, pp. 7, 9). Although nesting has not
been recorded for the blue-headed macaw, most parrots use natural tree
cavities or cavities within cliffs (Lee 2010, p. 4). This species is
reported to have low reproductive output in the wild (CITES 2002, p.
1), but this may be based on little data (Tobias and Brightsmith 2007,
p. 32). In captivity, the clutch size for blue-headed macaws is
reported to be 2-4 eggs (Vit 1997, as reported in Tobias and
Brightsmith 2007, p. 132). Female parrots generally incubate the eggs
and rely on the male for food, although in some species the males
contribute to incubation (Lee 2010, p. 5; Austin 1961, p. 33). Parrot
chicks are born blind and naked or with sparse down, which is white in
most species. The young of small parrots develop slowly and remain in
the nest for 3-4 weeks (Austin 1961, p. 33). Adult longevity in the
wild is unknown for the blue-headed macaw, but a congeneric (a species
belonging to the same taxonomic genus as another species), the blue-
winged macaw (Primolius maracana), is reported to live at least 31
years in captivity (Tobias and Brightsmith 2007, p. 132).
Conservation Status
The blue-headed macaw is currently classified as ``vulnerable'' by
the International Union for the Conservation of Nature and listed in
Appendix I of the Convention on International Trade in Endangered
Species of Wild Fauna and Flora (CITES). Species included in CITES
Appendix I are the most endangered CITES-listed species. They are
considered threatened with extinction, and international trade is
permitted only under exceptional circumstances, which generally
precludes commercial trade.
Summary of Factors Affecting the Blue-Headed Parrot
A. Present or Threatened Destruction, Modification, or Curtailment of
Habitat or Range
One of the main threats to neotropical parrot species, in general,
is deforestation (Snyder et al. 2000, p. 98). The Amazon region has the
world's highest absolute rate of deforestation (Laurance et al. 2002,
p. 738) and is currently threatened by increasing legal and illegal
logging, road projects, conversion of forests to agriculture, cattle
ranching, oil and gas extraction, and mining (Lee 2010, p. 2; MacLeod
2009, p. 6; Cowen 2007, p. 9; Magrin et al. 2007, p. 590; Tobias and
Brightsmith 2007, p. 134; Hume et al. 2006, p. 10; Asner et al. 2005,
p. 480; Alverson et al. 2001, p. 113; Laurance et al. 2001, p. 309;
Snyder et al. 2000, p. 98; Nepstad et al. 1999, p. 505). However, in
western Amazonia, especially in Peru and Bolivia where this species
occurs, the proportion of forest cover is still high and large tracts
of intact forests continue to exist even though some forests have been
cleared around some major towns (Finer et al. 2008, pp. 1, 6; Tobias
and Brightsmith 2007, p. 134; Kometter et al. 2004, p. 6). Information
on the extent of deforestation within the States or departments where
the blue-headed macaw occurs is limited; most information is at the
national level and may not necessarily apply to this species,
especially in Bolivia and Brazil where it occurs just inside the
borders of these countries.
Logging
Tropical forests, especially the Amazon, have experienced
increasing rates of deforestation for the past few decades, largely for
the conversion of land to food crops or pastures, and selective
harvesting of timber has increased in rate and extent (Granoff 2008, p.
553; Asner et al. 2005, p. 480; Laurance 1999, p. 112; Laurence 1998,
p. 411).
Selective logging targets older, larger trees that parrot species
depend on for nesting and food (Cowen 2007, p. 9; Hume et al. 2006, p.
11). The loss of these keystone trees may pose a threat to parrot
populations by creating a shortage of suitable nesting sites,
increasing competition, and causing the loss of current generations
through an increase in infanticide and egg destruction (Lee 2010, pp.
2, 12). If not managed correctly, selective logging may also cause
widespread collateral
[[Page 63483]]
damage to remaining trees, subcanopy vegetation, and soils (Asner et
al. 2005, p. 480). An additional 10 to 40 percent of the living biomass
of a forest may be damaged by a poorly managed logging harvest process
(Nepstad et al. 1999, p. 505) and can double the total amount of forest
degraded by human activities (Asner et al. 2005, p. 481). The loss of
trees may influence the availability and abundance of food sources for
the blue-headed macaw and may result in changes in diet or movement to
areas with greater food availability. Although individual blue-headed
macaws, nests, or eggs may be affected by logging activities, we have
no information to indicate impacts are occurring at a level affecting
the status of the species.
Typically, logging involves a low rate of extraction (less than 3
cubic meters (m\3\) per ha (106 cubic feet (ft\3\) per ac) and, if
implemented correctly, only removes as many trees as the forest can
regenerate (Colitt 2010, unpaginated; Rodr[iacute]guez and Cubas 2010,
p. 78). Because the valuable timber removed is often very old, long
intervals are needed for timber stands to recover from harvest
(Laurance 1999, p. 114), and if provisions are made for the
regeneration of these commercial trees, the effects of logging on tree
diversity and species composition may be short-lived (Fredericksen
2003, p. 10). In fact, if well managed, selective logging can mimic
natural disturbances, and if hunting pressure is low, most wildlife
species can persist in logged forests or recolonize harvested areas
from nearby unlogged patches (Laurance 1999, p. 114). Studies have
indicated a relatively minor impact on some wildlife species from
logging, and among those that may actually benefit are frugivorous
birds, such as the blue-headed macaw, due to the positive impact on
fruit abundance (Fredericksen 2003, p. 11). Additionally, frugivores
usually tolerate fragmentation better and are capable of using
deforested areas (Sekercioglu 2007, p. 285). Many parrots are not
habitat specialists and thrive in mosaics of different successional
habitats (Snyder et al. 2000, p. 99). Many species of lowland forest
habitat seem to do relatively well in modified human environments, as
long as a mosaic of habitats in different successional stages is
maintained and poaching and trapping are controlled (Snyder et al.
2000, p. 99). Although the blue-headed macaw could potentially benefit
from some logging activities, we found no information to what extent,
if any, this species benefits from these activities. However, species
experts have stated that the possibility of the species increasing with
the spread of degraded forests along rivers cannot be discounted
(Tobias and Brightsmith 2007, pp. 132-133) and Hennessey (2011, pers.
comm.) has stated that the blue-headed macaw populations in Peru and
Bolivia have remained healthy.
Peru
With approximately 68 million forested hectares (ha) (168 million
acres (ac)) covering 53 percent of its land area, Peru has the second
most extensive forests in Latin America, after Brazil (FAO 2011, p.
118; Salo and Toivonen 2009, p. 610). In the early 2000s, Peruvian
Amazonia experienced a series of forestry reforms, including the
implementation of forest concessions (forest leases), which led to a
rush for newly allocated timber resources (Salo and Toivonen 2009, p.
609; Oliveira et al. 2007, p. 2). More than 7 million ha (17.2 million
acres; approximately 10 percent of the country's forest) are now
designated as forest concessions in the regions of Ucayali, Loreto,
Madre de Dios, San Martin, and Huanco; another 18 million ha (44.5
million ac; nearly a quarter of Peruvian forests) are still potentially
available for concession designation in the near future
(Rodr[iacute]guez and Cubas 2010, p. 79; Salo and Toivonen 2009, pp.
609-610).
The aim of the forestry reform was to target issues such as control
and enforcement of forestry activities, as well as illegal forestry
activities (Salo and Toivonen 2009, p. 610). Part of the new forestry
reform included a new forestry law (See Factor D) which classified
Peru's forests into 6 categories, including permanent production
forests. This category includes those forests in which forest
concession contracts can be assigned. A concession contract gives the
holder the right to exploit the resources within a given area, but also
gives the holder responsibility to manage the resources (Salo and
Toivonen 2009, p. 611). Studies have shown that forest concessions in
Peru have provided forests with protection from deforestation (Salo and
Toivonen 2009, p. 620; Oliveira et al. 2007, pp. 2-3). Although we do
not know the exact location of the recently designated 7 million ha
(17.2 million acres) of forest concessions, they do not appear to have
impacted the blue-headed macaw, given that the range has remained 90
percent forested and there is no evidence in a decline in the range or
population of this species. We do not know where the 18 million ha
(44.5 million ac) of potential forest concessions are located in
regards to locations of blue-headed macaw; however, if located within
the range of this species, data suggest that these concessions could
provide forests with protection against deforestation.
To date, the forests of Peru, including large areas within the
range of the blue-headed macaw, have mainly been subjected to selective
logging (Salo and Toivonen 2009, p. 610; Tobias and Brightsmith 2007,
p. 134; Fredericksen 2003, p. 10), which has contributed to only 2.5
percent of Peru's overall deforestation (Salo and Toivonen 2009, p.
610). Nonetheless, there are reports of illegal logging in Peru,
including one study that found evidence of illegal logging within the
Muruanahua Reserve and Alto Pur[uacute]s National Park in Peru, which
is a known location for the blue-headed macaw (Upper Amazon Conservancy
2010, unpaginated; World Wildlife Fund in Indian Country Today 2007,
unpaginated). However, there is no evidence that selective logging
removes habitat for this species (Tobias and Brightsmith 2007, p. 134).
Furthermore, it is possible that the blue-headed macaw could benefit
from logging given that frugivores tend to benefit from logging due to
the increase in fruit availability, and lowland habitat species, such
as the blue-headed macaw, do well in modified human environments if
successional forests are left intact and poaching is controlled. In
addition, species experts have stated that the possibility that the
species is increasing with the spread of degraded forests along rivers
cannot be discounted (Tobias and Brightsmith 2007, pp. 132-133).
Because the range of the blue-headed macaw has remained 90 percent
forested and there is no evidence of a decline in either the range or
population, we have no indication that selective logging or illegal
logging has impacted the blue-headed macaw. Large areas within the
range of the blue-headed macaw are slated for selective logging (Tobias
and Brightsmith 2007, p. 134); however, because there is no evidence
that selective logging removes habitat, and in fact the species may
benefit from selective logging, we have no reason to believe that
future selective logging activities in Peru will be a threat to this
species.
In summary, we find that deforestation via current forest
concessions and selective logging have not impacted the status of the
blue-headed macaw based on the fact that the range has remained 90
percent forested and there is no evidence of a decline in the range or
population of this species. Although we do not know the locations of
the forest concessions that may be designated in the future, if they
are located within the range of the blue-headed macaw, they may provide
[[Page 63484]]
protection to blue-headed macaw habitat from deforestation.
Furthermore, we found no information indicating that the known areas of
the blue-headed macaw's range that are slated for selective logging
will impact the status of the species; in fact, it is possible that the
species could benefit. Additionally, there are several conservation
programs being implemented in Peru to address deforestation (see
Conservation Programs below). Therefore, we have reason to believe that
future deforestation will not impact the status of this species in
Peru.
Bolivia
Approximately 57.2 million ha (141.3 million ac) (53 percent) of
Bolivia's total area is forested (FAO 2011, p. 118); of this forested
area, 38.9 million ha (96.1 million ac) are within the Bolivian Amazon
and constitute 5 percent of the total Amazon forest (Locklin and Haack
2003, p. 774). Large tracts of primary forest remain in Bolivia, but it
is likely that some of these will be subjected to logging (Fredericksen
2003, p. 13) as forest products contribute to Bolivia's national
exports (Byers and Israel 2008, p. vi). As of 2006, 89 timber companies
held the rights to 5.8 million ha (14.3 million ac) of logging
concessions (Pacheco 2006, p. 208). The forests of Bolivia have mainly
been subjected to selective logging (Salo and Toivonen 2009, p. 610;
Fredericksen 2003, p. 10), which has been done at very low levels and
with low human pressure, allowing them to remain largely intact
(Fredericksen 2003, p. 10). There are management issues that still need
to be addressed, including sufficient regeneration time for commercial
species (Fredericksen 2003, p. 10). However, given that Bolivia
constitutes only a small part of this species' range, and the fact that
we found no information indicating that logging has impacted the blue-
headed macaw range or population in any of its range countries, we have
no reason to believe that logging is a threat to the species in
Bolivia. Furthermore, we have no information indicating any future
logging activities will impact the blue-headed macaw.
Brazil
Brazil contains 519.5 million ha (1.2 billion ac) of forested area,
62 percent of the total land area (FAO 2011, p. 118). Logging
concessions total only 150,000 ha (370,658 ac) (Colitt 2010,
unpaginated). However, by the end of 2010, Brazil was to have auctioned
off an additional 1 million ha (2.5 million ac) of forest concessions
to private companies in an effort to reduce the demand for illegal
logging. Concessions help establish control over public areas usually
occupied illegally (Colitt 2010, unpaginated).
Logging is occurring in blue-headed macaw habitat in extreme
western Brazil, but this species is a generalist and can exist within
degraded habitats. Rond[ocirc]nia and Acre are among Brazil's major
timber-production states (Asner et al. 2005, p. 480); however, this
species occurs just inside the border of western Brazil and we found no
information suggesting that the range or population of the blue-headed
macaw have been impacted by logging in Brazil and no information
indicating logging may affect this species in the future.
Large areas within the range of the blue-headed macaw have
experienced, or are slated for, selective logging (Tobias and
Brightsmith 2007, p. 134), and designation of forest concessions could
potentially cause changes in land-use practices, perhaps affecting
plant and wildlife species composition and diversity of an assigned
area (Salo and Toivonen 2009, p. 610; Fredericksen 2003, p. 10).
However, BLI (2011a, unpaginated) reports that ``much of the forest
within the species' range is still intact, and although the Bolivian
forest is threatened by expansion of the logging industry, this species
may benefit from the consequent patchwork clearance.''
Ninety percent of the range of the blue-headed macaw remains
forested, and there is no evidence of a decline in either the range or
the population. Logging could affect individual blue-headed macaws
though the loss of food or nesting resources; however, considering the
extent of intact forests within the range of this macaw and no evidence
of a decline in the population (Tobias and Brightsmith 2007, p. 134),
as well as the possibility that the blue-headed macaw is increasing
with the spread of degraded forests along rivers (Tobias and
Brightsmith 2007, pp. 132-133), we have no evidence to suggest that
logging is affecting the blue-headed macaw to a degree that it is
affecting the status of the species. Additionally, we have no
information to suggest that logging may become a threat to the status
of the blue-headed macaw in the future.
Roads and Infrastructure
Oliveira et al. (2007, p. 2) estimated that 75 percent of the total
Peruvian Amazon forest damage was within 20 km (12.4 mi) of the nearest
road. In Bolivia, studies have detected small-scale roadside
deforestation extending over 30 km (18.6 mi) from major roads
(Steininger et al. 2001, p. 132). Studies on the effects of roads on
deforestation in the Brazilian Amazon have shown a 30 percent forest
loss within 10 km (6.2 mi) of roads and highways, with highways causing
an additional 20 percent forest loss within 11-25 km (6.8-15.5 mi), and
15 percent loss within 26-50 km (16-31 mi) (Zambrano et al. 2010, p.
158). Despite the deforestation occurring along roads and highways, the
range of the blue-headed macaw is 90 percent forested, and we found no
information indicating that the species has been impacted by roads or
any subsequent deforestation. In fact, species experts (Hennessey 2011,
pers. comm. and Tobias and Brightsmith 2007, p. 134) indicate that this
species is doing well, despite some localized impacts from
infrastructure and roads.
The Initiative of the Integration of the Regional Infrastructure of
South America (IIRSA) is a plan endorsed by the South American
presidents, which includes around 350 infrastructure projects, such as
highways, bridges, railways, ports, airports, and transmission
corridors, to accomplish regional economic integration and facilitate
trade (Babbitt 2009, pp. 28-29). At the center of this plan is the
nearly complete Transoceanic Highway, a 1,000-km (621.3-mi) highway
that connects the Brazilian State of Acre to the Peruvian coast,
passing through Puerto Maldonado (Garcia-Navarro 2009, unpaginated;
Babbitt 2009, p. 28; Tobias and Brightsmith 2007, p. 134) and near
several other locations in which the blue-headed macaw has been
recorded, bisecting its range (Tobias and Brightsmith 2007, p. 134).
The blue-headed macaw occurs within the immediate outskirts of Puerto
Maldonado, one of the areas with significant disturbance, suggesting
that this species is not greatly affected by anthropogenic pressures
(Brightsmith 2009, pers. comm.; Tobias and Brightsmith 2007, p. 129).
Future urban expansion in Puerto Maldonado resulting from the
highway may put pressure on the protected area of Tambopata (Delgado
2008, p. 27), where the blue-headed macaw has been recorded. Although
the Transoceanic Highway is not located within Bolivia, the connection
between Cobija, Bolivia, and Brasil[eacute]ia, Brazil, allows Cobija, a
recorded location for the blue-headed macaw, to benefit from the road
project and potentially grow in the future (Delgado 2008, p. 31).
Additionally, IIRSA plans to build another highway that would branch of
from the Transoceanic Highway in Rio Branco, the capital of Acre. If
completed, this highway will run through the forests of Serra do
Divisor National Park, a known
[[Page 63485]]
location for the blue-headed macaw (Babbitt 2009, p. 31). In spite of
this information, we found no indication that the range, habitat, or
population of the blue-headed macaw has been impacted by the
Transoceanic Highway. Given that the species has not been adversely
affected by road construction or other infrastructure, we have no
information suggesting that the status of this species may be impacted
in the future by the Transoceanic Highway.
Although there has been road development within Peru, Bolivia, and
Brazil, and individual blue-headed macaws could potentially be affected
by road development through the loss of food and nesting resources, we
have no information indicating that the status of the species has been
adversely impacted by this development in the past. The range remains
90 percent forested and there is no evidence that the range or
population has declined. Furthermore, Brightsmith (2009, pers. comm.)
notes that although road construction and related deforestation may
affect part of the blue-headed macaw's range, habitat analyses to date
show no evidence that deforestation will adversely affect the species
in the future.
Agriculture and Ranching
Logging and modern roads facilitate infiltration into pristine
forests by migrant settlers who use slash-and-burn methods for
agriculture and cattle pastures (Laurance 1998, p. 411). Slash-and-burn
agriculture involves the clearing of land and burning of debris
(Locklin and Haack 2003, p. 775; Nepstad et al. 1999, p. 505). Often,
plots are abandoned after only two or three cycles, and then more
forests are cleared to establish new plots (Reyes-Garc[iacute]a et al.
2007, p. 406; Duery and Vlosky 2005, p. 10). Production may be limited
to subsistence farming if roads are in poor condition or if the cost of
transportation is high. However, if roads are in good condition and
provide access to international and national markets, production may
expand to cash crops (Zambrano et al. 2010, p. 158; Locklin and Haack
2003, p. 780).
Agriculture is considered the main cause of deforestation in the
lowlands of Bolivia (Pacheco 2006, p. 215). With pressures for
agriculture expansion, large areas are being cleared for both soybean
farms and cattle ranches (Pacheco 2006, pp. 213, 216; Duery and Vlosky
2005, p. 10; TNC 2001, unpaginated: Laurance 1998, p. 411). The San
Buenaventura-Puerto Heath road runs through the Madidi National Park, a
known location of the blue-headed macaw. The greatest human-caused
impact along this road was the conversion of forest via slash-and-burn
agriculture, although rates of deforestation were relatively low
(Locklin and Haak 2003, pp. 775, 778). Forest clearance patterns of
indigenous communities practicing shifting cultivation have been
observed, particularly along rivers, throughout Beni, Pando, and La Paz
(Steininger et al. 2001, p. 131). Reyes-Garc[iacute]a et al. (2007, p.
406) found that the Tsimane', a native Amazonian society within Beni,
practice slash-and-burn agriculture and abandon their plots after one
or two cultivation cycles to establish new plots. This society is also
moving from subsistence farming towards cash crops, which requires
additional forest clearing and contributes to further deforestation
(Reyes-Garc[iacute]a et al. 2007, p. 407). We have no information
indicating that the blue-headed macaw has been or will be impacted by
agriculture in Bolivia, and given that Bolivia is such a small portion
of the species' range, we have no reason to believe agricultural
expansion is affecting or will affect this species at the population
level.
Current expansion of deforestation in Bolivia Amazonia is also
associated with cattle ranching (Pacheco 2006, p. 216). Its
contribution to deforestation is expected to increase in the future due
to topographical limitations of mechanized agriculture. In Beni, the
impacts of cattle ranching may be a greater concern, as 65 percent of
all the cattle herds in Bolivia are located here (Pacheco 2006, pp.
215-216). However, the species' range in Bolivia is limited to just
inside the border and we have no information indicating that the blue-
headed macaw has been impacted, or could be impacted, by cattle
ranching in that area of its range.
In Brazilian Amazonia, cattle production is the dominate land use
in deforested areas and is the main factor driving deforestation
(Pacheco 2006, p. 223; Laurance 1999, p. 113; Fearnside 1996, p. 21).
Large-scale ranchers (those that own over 100 ha (247 ac)) are thought
to be responsible for 70-75 percent of all the deforestation in this
region (Laurance 1999, p. 113). Furthermore, illegal slash-and-burn
practices have already destroyed 20 percent of the Brazilian Amazon
(Colitt 2010, unpaginated). The States of Rond[ocirc]nia and Acre,
where the blue-headed macaw occurs, are currently experiencing
conversions of forest for agriculture and cattle ranching (Tobias and
Brightsmith 2007, p. 134). However, given this species' limited range
just inside the border of Brazil and its ability to thrive in altered
habitat, coupled with no information indicating that cattle ranching
has impacted, or will impact, the blue-headed macaw within its limited
range in Brazil, we do not believe that cattle production is currently,
or will be a threat to this species, now or in the future.
Although the migration of settlers, and the subsequent farming, has
been named by some as a contributing factor to deforestation in Peru
(Painter 2008, unpaginated; Hume et al. 2006, p. 3), we found little
information on the extent of deforestation due to agriculture. In
Man[uacute] National Park, 63,500 ha (156,911 ac) of 1.7 million ha
(4.2 million ac) were deforested up to the year 2005 for agricultural
activities (Cabieses 2009, p. 26). However, since 2006, the Integrated
Programme to Strengthen the Local Capacity of Small Farmers of the
Man[uacute] Biosphere Reserve Buffer Zone of Peru has worked with
families within the park to foster activities compatible with organic
farming and incorporate natural resource management into agricultural
activities. By 2008, 530 families helped reforest 151 ha (373 ac) with
mostly native species (Cabieses 2008, pp. 26-27). In the area
surrounding Cordillera Azul National Park (a recorded location for the
blue-headed macaw), the rate of deforestation due to the coffee and tea
plantations and cereal grain farms (Chatterjee 2009, p. 557) has
increased. The core zone of the Park is largely free of human
inhabitants, with the exception of one rancher with 220 ha (543.6 ac)
of pasture and some reports of indigenous people in the southeastern
part of the Park. In 2008, the Peruvian government granted a 20-year
contract to the Peruvian NGO Centro de Conservaci[oacute]n,
Investigaci[oacute]n y Manejo de Areas Naturales Cordillera Azue (CIMA)
that allows CIMA to manage the park under the supervision of the State
and according to clearly defined guidelines. (Ostoic n.d., p. 1). In
addition, we found no information indicating agriculture in any of the
range states has impacted, or will impact, the blue-headed macaw, thus
we do not believe it will impact the species in Peru, especially given
the limited and localized nature of agriculture activities.
Agriculture and cattle ranching activities are currently taking
place within the range of the blue-headed macaw, especially within
Bolivia and Brazil. However, given that these two countries make up a
minimal part of the species range, it is unlikely to have any effect on
the species. Although it is possible that individual blue-headed macaws
could be affected by these activities through the loss of food or
nesting resources, we have no information indicating the species has
been adversely impacted by either
[[Page 63486]]
activity; in fact, the blue-headed macaw seems to benefit from some
fragmented habitat. There is no evidence of a decline in the range or
population of the blue-headed macaw and 90 percent of the species'
range remains forested. Both agriculture and cattle ranching are
expected to expand in the future; however, we have no information on
the extent of this expansion and no information indicating either
activity will be a threat to the species in the future.
Oil and Gas
The western Amazon contains large reserves of oil and gas, many
that are yet untapped (Finer et al. 2008, p. 1). Global demand for
energy and record oil prices have launched unprecedented levels of oil
and gas exploration and extraction in western Amazonia, with some of
the most intense activity occurring in Peru (Kolowski and Alonso 2010,
p. 917; Babbitt 2009, p. 31; Finer et al. 2008, p. 1).
National governments have delineated specific areas, or blocks,
that are zoned for hydrocarbon (e.g., natural gas and petroleum)
activities; these blocks may be leased to state and multinational
energy companies for exploration and production (Finer et al. 2008, p.
1). In western Amazonia, there are approximately 180 oil and gas blocks
covering about 688,000 km\2\ (265,638 mi\2\), which are operated by at
least 35 multinational companies (Finer et al. 2008, p. 2). These oil
and gas blocks may bring new access routes throughout the area,
contributing to deforestation, as it did in eastern Amazonia and the
southern Brazilian Amazon (Finer et al. 2008, p. 6).
In 2003, Peru reduced royalties to encourage investment and sparked
an exploration boom. As of 2008, 72 percent of the Peruvian Amazon was
zoned for oil and gas by the government into 64 separate blocks; 48 of
these blocks are currently active, the others may be subjected to
active exploration in the near future (Kolowski and Alonso 2010, p.
917; Finer et al. 2008, pp. 2, 5). The only areas fully protected from
oil and gas activities are national parks and national and historic
sanctuaries, which cover approximately 12 percent of the Peruvian
Amazon. However, 20 blocks overlap with 11 less strictly protected
areas, such as communal reserves and reserved zones (Finer et al. 2008,
p. 2). Although oil and gas exploration and production are occurring in
Peru, we have no information indicating that the blue-headed macaw has
been impacted, or will be impacted, by oil and gas activities in Peru.
In Bolivia and Brazil, areas open to oil and gas explorations are
increasing rapidly (Finer et al. 2008, p. 2). In Bolivia, two leased
blocks, covering 15,000 km\2\ (5,791 mi\2\), include large parts of
Madidi National Park, a recorded location for the blue-headed macaw, as
well as other parks where the blue-headed macaw has not been recorded;
exploration in this region is imminent. The primary task of a newly
created oil company, comprised of the State oil companies of Bolivia
and Venezuela, is to explore for oil in newly created blocks
surrounding Madidi National Park. Many other blocks in Bolivia overlap
with protected areas (Finer et al. 2008, p. 5). We have no information
indicating that the blue-headed macaw has been adversely impacted by
oil and gas exploration in Bolivia; species experts have indicated that
there is no evidence of a decline in the range or population of the
blue-headed macaw (Tobias and Brightsmith 2007, p. 134) . Furthermore,
we do not have information to indicate that the species will be
impacted by future oil and gas exploration in Bolivia.
In Brazil, a 400-km (248.5-mi) gas pipeline was completed in 2009,
running from Urucus gas field (State of Rond[ocirc]nia) to Manaus
(State of Amazonas). Another 500-km (310.6-mi) pipeline has been
proposed to carry gas to Porto Velho in Rond[ocirc]nia. Additionally,
Brazil's National Petroleum Agency has announced plans to look for oil
and gas in the State of Acre, on the border with Peru and Bolivia
(Finer et al. 2008, p. 5), an area that contains known locations for
the blue-headed macaw. Oil and gas exploration and production do not
necessarily impact parrots. Drilling operations often have a smaller
footprint than other extractive activities, and this is further reduced
once the well is installed. Further, we found no information that
existing oil and gas operations have impacted any parrot populations in
any of the range countries. Because there is no evidence of a decline
in the range or population of the blue-headed macaw in Brazil, we have
no information indicating that the blue-headed macaw has been impacted
by oil and gas exploration in Brazil. Furthermore, we do not have
information to indicate that the species will be impacted by future oil
and gas exploration in Bolivia.
Pending oil and gas projects are the primary threats to Peru's
Camisea region and Bolivia's Madidi region (Finer et al. 2008, p. 6).
Although individual blue-headed macaws could potentially be affected by
oil and gas explorations through the loss of food or nesting resources,
there is no evidence of a decline in the range or population of the
blue-headed macaw, and we have no information indicating that the
species has been adversely impacted by oil and gas exploration.
Furthermore, we have no information to indicate that the species will
be impacted by future oil and gas exploration.
Mining
Over the last decade, the price of gold has increased 360 percent,
with an annual rate of increase of approximately 18 percent;
subsequently, the number of non-industrial gold mining operations in
developing countries has risen (Swenson et al. 2011, p. 1). Many of
these operations are illegal, as they are set up by residents without
permits or formal title to the land, and without an environmental
impact analysis or miner education (Swenson et al. 2011, p. 1).
In Peru, the expansion of gold mining has been encouraged by the
Transoceanic Highway, which has drawn impoverished Peruvians into the
lowlands in search of a livelihood and hoping to strike it rich
(Garcia-Navarro 2009, unpaginated). Madre de Dios is currently
undergoing a new gold rush due to the high price of gold, increased oil
and gas activities, and the completion of infrastructure projects
(Hajek et al. 2011, in press). This region is Peru's third largest
producer of gold and accounts for 70 percent of Peru's artisanal
(small-scale or subsistence miner) gold production (Swenson et al.
2011, p. 2). Concurrent with increasing annual gold prices, mining
deforestation has been increasing since 2003. From 2003 to 2006, annual
mining deforestation was approximately 292 ha (721.5 ac) per year. From
2006 to 2009 this rate increased to 1,915 ha (4,732 ac) per year, a
six-fold increase (Swenson et al. 2011, p. 4). Furthermore, Swenson et
al. (2011, pp. 4-5) found that mining deforestation in this area is
outpacing deforestation due to settlements, although this scenario
might be different for areas with more secondary roads, which tend to
correlate with higher rates of deforestation. One study found that
forest recovery following small-scale gold mining was extremely slow
and qualitatively inferior to regeneration following other human-caused
disturbances (Mol and Ouboter 2003, p. 202). However, these operations
are typically small and require very little land-clearing. Given the
relatively small amount of land conversion for gold mining, we found no
information indicating that deforestation via mining has impacted the
blue-headed macaw, nor did we find any information
[[Page 63487]]
indicating this species will be impacted by mining in the future.
In addition to deforestation, impacts to the environment from gold
mining stem from acid mine drainage and air and water pollution from
contaminants, such as mercury. During gold processing, mercury is
released into sediments, waterways and the atmosphere. As parrots are
known to use riverside clay licks, they may be at risk of mercury
entering their systems when they ingest soil particles. Many developing
countries have reached agreements with large gold mining companies that
do not use mercury, but regulating small-scale, artisanal mines
continues to be a struggle (Swenson et al. 2011, pp. 1, 5).
Furthermore, gold miners might actively erode riverbanks, which may
include essential clay licks used by parrots (Lee 2010, p. 12).
However, we have no information indicating that mining has affected the
blue-headed macaw.
Permits for mining require an environmental impact report. Madre de
Dios has the highest number of unapproved mining permits in Peru;
moreover, there is little effective enforcement of unapproved permits
or illegal miners, and therefore, little incentive to apply for a
permit (Swenson et al. 2011, p. 2). Miners are able to use waterways
for transportation and are capable of invading far reaches of
communities and protected areas. Lack of funding, staff, and staff
training makes patrolling these remote areas difficult (Swenson et al.
2011, p. 5). Two of the three mining sites studied by Swenson et al.
(2011, p. 4) are located less than 7 km (4.3 mi) from the Amarakaeri
Communal Reserve and less than 70 km (43.5 mi) from Manu National Park.
In a study of 54 national parks in Latin America, mining was considered
a threat in approximately 20 (37 percent) of the parks, of which 11 (55
percent) were located in Peru (Swenson et al. 2011, p. 4). Peru's newly
created Ministry of Environment is working to control illegal mining,
and a recent effort was made through a moratorium on new mining
concessions (Swenson et al. 2011, p. 5).
In addition to the major mining growth centers, there are many
small expanding areas of mining scattered across Madre de Dios, which
are harder to detect (Swenson et al. 2011, p. 5). Rising annual gold
prices and an increasing number of miners setting up illegal mines may
fragment once large areas of pristine forests. Although individual
blue-headed macaws could potentially be affected by mining through the
loss of food or nesting resources, we have no information that the
species has been adversely impacted by mining. In fact, this species
tends to benefit from patchwork clearance of forests (BLI 2011a,
unpaginated). Furthermore, we do not have any information indicating
the species may be impacted by future mining operations.
Conservation Programs
A new mechanism is emerging that may raise funds to protect forests
from deforestation, as well as mitigate climate change. This mechanism
is known as ``reduced emissions from deforestation and forest
degradation'' (REDD). As forests are destroyed for logging, mining, or
oil and gas, the carbon stored in the trees is released as carbon
dioxide, which adds to the concentration of greenhouse gases; 20
percent of global greenhouse gas emissions are thought to be from
deforestation (Chatterjee 2009, p. 557). Lawmakers and businesspeople
around the world are beginning to consider investing in REDD programs
as a way to mitigate climate change. Under this type of program,
developing countries would be paid to protect their forests and reduce
emissions associated with deforestation. Funds would come from
foundations, governments, or financial agencies such as World Bank;
industries in developed countries would receive credits for saving
trees in developing countries (Chatterjee 2009, p. 557). If REDD
projects are able to generate revenue comparable to those of activities
such as logging and agriculture, and revenues are distributed equally
among stakeholders, this would give standing forests value and an
incentive for forest conservation (Hajek et al. 2011, in press). REDD
projects are emerging in many regions (Hajek et al. 2011, in press);
however, we do not yet know the occurrence of these projects within the
range of the blue-headed macaw and how successful these projects will
be.
Another program being implemented is certification of forests. The
basis for certification is for consumers to be assured by a neutral
third party that forest companies are employing sound practices that
will ensure sustainable forest management. By being certified, a
company can differentiate their products and potentially acquire a
larger share of the market (Duery and Vlosky 2005, p. 12). To be
certified, companies must follow standards set by the Forest
Stewardship Council (FSC). Certification companies not only certify
forests, but also forest products that come from well managed forests
and may also provide a means to track logs and remove illegally logged
trees from the market (Duery and Vlosky 2005, pp. 13-14; Kometter et
al. 2004, p. 9). To date, more than 670,000 ha (1.6 million ac) of
Peru's forest have achieved FSC certification (Rodriguez and Cubas
2010, p. 78). Bolivia has the largest area of FSC-certified tropical
forests in the world; by the mid-2000s, Bolivia announced that 2.2
million ha (5.4 million ac) of humid tropical forests were certified
(Killeen et al. 2007, p. 600; Duery and Vlosky 2005, p. 14). In 2004,
Brazil announced that 1.2 million ha (2.9 million ac) of native Amazon
forests and 1.0 million ha (2.4 million ac) of plantations were
certified (WWF 2004, unpaginated). The FSC promotes ``the equitable
incorporation of social and environmental considerations when decisions
are taken to manage forests. Under FSC certification, civil and
indigenous rights are respected, areas of high social and environmental
conservation value are maintained or enhanced, natural forests are not
converted, highly hazardous pesticides and genetically modified trees
are prohibited, and harvesting must meet national laws and
international treaties.'' Furthermore, forests that are ``FSC certified
forest products'' are verified from the forest of origin through the
supply chain. The FSC label ensures that the forest products used are
from responsibly harvested and verified sources (FSC n.d.,
unpaginated).
In 2008, Peru announced its intention to reach zero deforestation
within just 10 years. The Peruvian government stated that more than 80
percent of the country's primary forests could be saved or protected
with about $20 million U.S. dollars (USD) a year from the international
community. However, there are major obstacles to achieving this goal.
Additionally, Peru launched in 2010 its National Program for the
Conservation of Forests and Mitigation of Climate Changes. This program
aims to preserve 54 million hectares (133 million acres) of the 72
million hectares (178 million acres) of tropical forest in the Peruvian
Amazon, although it is expected that the entire area consisting of 72
million hectares will be included (La Cruz 2010, unpaginated).
Similarly, Brazil announced a plan to cut deforestation rates by 70
percent over the next 10 years with the help of international funding.
Brazil's plan calls on foreign countries to find $20 billion USD by
2021 (Painter 2008, unpaginated). All three countries have committed to
protecting their forest resources in the future and have moved towards
their goals to reach zero deforestation by certifying nearly 4 million
ha (10 million ac) of forests.
[[Page 63488]]
There are many obstacles to overcome to reach these goals, including
annual funding. If these programs are implemented and goals reached,
deforestation in the Amazon will be significantly reduced.
Summary of Factor A
It is clear that the forests of the Amazon are being deforested for
various economic activities, and deforestation rates have been
increasing for several decades. How a species responds to this type and
level of habitat disturbance depends on the preferences of the
individual species, and the distance of undisturbed rainforest near
disturbed areas. Many parrots are not habitat specialists and thrive in
mosaics of different successional habitats. Many species of lowland
forest habitat seem to do relatively well in modified human
environments, as long as a mosaic of habitats in different successional
stages is maintained and poaching and trapping are controlled (Snyder
et al. 2000, p. 99).
Although we do not know the exact extent of current deforestation
within the specific areas occupied by the blue-headed macaw, especially
within Bolivia and Brazil where the species occurs just inside the
countries' borders, there is no evidence that deforestation has
impacted the blue-headed macaw. Ninety percent of this species' range
is still forested. There is no evidence of a decline in the range or
population and populations within Peru and Bolivia have remained
healthy. At a minimum, the population numbers 11,500 individuals
(including immature individuals), and this may be an underestimate as
the entire global range has not been surveyed. Furthermore, blue-headed
macaws at the Tambopata Research Center have been increasing since
2000, and sightings of the blue-headed macaw in Peru have increased
over the last 10 years. Additionally, it has been found in a wide range
of habitats, and is slightly more common in degraded habitats than
pristine forests. The blue-headed macaw still occurs on the outskirts
of Puerto Maldonado, Peru, one of the areas with significant
disturbance, suggesting that this species is not greatly affected by
anthropogenic pressures. Species experts have even suggested that the
blue-headed macaw may increase with the spread of degraded forests
along rivers.
Although there is evidence that forest habitat within the species
range is subject to selective logging, the patchwork clearance as a
consequence of logging may benefit the species. Furthermore, we found
no information that selective logging has adversely impacted the
species. Additionally, road construction and related deforestation that
are likely to affect the region in which the blue-headed macaw occurs
is not likely to adversely affect the species. It is possible that
individual blue-headed macaws may be affected by economic activities
involving deforestation, such as logging, road development, agriculture
and cattle ranching, oil and gas exploration, and mining, through the
loss of food or nesting resources; however, we have no evidence to
suggest that deforestation is affecting the blue-headed macaw to a
degree that it is affecting the status of the species. Based on the
best scientific and commercial information available, we find that
deforestation from various economic activities, as discussed above, is
not adversely impacting the blue-headed macaw and has not affected the
range or status of the species. Additionally, we do not anticipate
significant modification to the blue-headed macaw's habitat or
curtailment of its range due to deforestation in the foreseeable
future. A vast amount of the species' range has remained forested
through
