Dear Dr. Thomas:
The Species Survival Network Working Groups on Bird
Trade and Wildlife Use jointly submit the following
comments in regard to the U.S. Fish and Wildlife Service's
(the Service) Proposed Rule for the addition of Amazona
aestiva in Argentina to the approved list of non-captive
bred birds under the U.S. Wild Bird Conservation Act
(WBCA) of 1992. Throughout our comments, Argentina’s
Management plan for Amazona aestiva is referred to as
“the Plan”.
We urge you to reject the proposed action for the following
reasons:
1. Regarding the capture of adult and juvenile birds
The Plan provides economic incentives for farmers to
declare the species as a pest.
There is no basis for Argentina’s legal designation
of Amazona aestiva as a pest as crop damage caused by
the species is negligible (less than 1% (Navarro et
al. 1991)). We are concerned that, in allowing the harvest
of juveniles, the Plan promotes the use of lethal control
methods and provides an economic incentive for farmers
to declare the species as a pest, a view supported by
the Service in its Draft Environmental Assessment (2002).
Such takes are more likely to be based on financial
need rather than science.
The WBCA requires that for species that are considered
“pests” in the country of origin, such as Amazona aestiva,
the Plan shall include, “documentation that such a species
is a pest” (50 CFR 15.32 (6)(i)). Not only does the
Plan fail to include such documentation but field research
confirms that damage caused by the species is negligible
(Navarro et al. 1991)1. We believe that the species
would be best conserved by revoking its status as a
pest species, adopting a prohibition on hunting and
promoting safer, more effective control methods in agriculture
areas.
The Plan´s capture of adults and juveniles is not scientifically
based and risks overexploitation.
The Plan
sets the capture quota for takes of juvenile and adult
birds at one-third the number of birds taken from nests.
Though the WBCA requires that the Plan be “scientifically
based” (WBCA Sec. 106 (c) (2)) and include “documentation
of how each level of take was determined” (50 CFR 15.32
(5)(iv)), no scientific information is provided on the
methodology used for setting quotas for this age group.
In addition, captured juveniles and adults may be from
the same populations that are subject to exploitation
in the nesting areas—seriously risking overexploitation.
In the Proposed Rule, the Service states that, “it is
unlikely that the flocks observed in the citrus groves
are those that nest on the properties participating
in the program” yet, experts state that seasonal movements
do occur and that “birds nesting in Argentine Chaco
move west to Andean foothills outside the breeding season
(Juniper and Parr 1998)”—the same areas included in
the management Plan.
We note, in this regard, that blue-fronted amazons are
actually more likely to prove serious crop pests in
the United States, where they lack natural predators,
than in their native habitat. Feral parrot populations
established by escaped pets have become seriously invasive
in several countries. In fact, imports of Amazona aestiva
itself are already prohibited in some jurisdictions
because of the threat non-native parrots pose to crops
and native wildlife.
The use of leg-snares to capture free-flying adult and
juvenile parrots is cruel and inhumane.
In the Service’s
Draft Environmental Assessment (2002), the Service expressed
concern about health risks for parrots associated with
using leg snares. These concerns have been deleted from
the Proposed Rule and, instead, the Service defends
the use of leg snares to capture juvenile and adult
birds by stating that “no birds were euthanized as a
result of injuries from leg snares.” The Proposed Rule
fails to reveal whether birds have been killed outright
by the traps (making euthanasia unnecessary); nor does
it consider the likelihood that injured birds may simply
be discarded outside the presence of program monitors.
2. Regarding the capture of nestlings
The Plan’s capture level for nestlings is not biologically
sustainable and will result in overexploitation.
Capture
levels for nestlings are based on the combined restrictions
of leaving one chick in each nest and a quota of two
birds per 20 hectares. Based on data available from
Proyecto Éle (Banchs, et al. 2000), the Service states
in the Proposed Rule that a nest typically contains
3 hatchlings, of which 2 nestlings survive to fledge.
Based on the information presented, the restriction
of leaving one chick in the nest to fledge would reduce
natural recruitment by at least 50%--hardly sustainable,
particularly for a species that continues to decline
through much of its range (Bucher 2000). ). This offtake
is in addition to substantial mortality rates chicks
will suffer due to natural factors. The combined impact
of direct harvest and natural mortality could lead to
complete failure in up to one-third of the harvested
nests.
The Plan’s estimated nest density for the species of
one nest per 20 hectares is more than 20 times greater
than previous estimates of nest density for the species
in Argentina (Bucher et al. 1995). The Plan’s estimate
is based on unpublished data that has not been peer
reviewed. The Service states that exports of the species
have not fulfilled the established quotas. This may
be an indication that the quotas exceed the productive
capability of the population.
The Plan does not take a cautious, conservative approach
in response to the lack of key biological information.
In the absence
of detailed biological information (population size
and range, habitat requirements, movement, estimates
of demographic rates, key factors that regulate population,
effects of environmental variation), Beissinger and
Bucher (1992) recommend the use of the Conservative
Sustainable Harvest Model (CSHM). This model allows
for the capture of excess birds produced by management
techniques proven to increase production of the species
such as, the use of nest boxes or by decreasing predation.
The Argentine Plan does not include efforts to increase
production. In addition, Beissinger and Bucher (1992)
state that the CSHM is only applicable to increasing
or stable populations; the model cannot be utilized
for a species such as Amazona aestiva which continues
to decline through much of its range (Bucher 2000).
3. Regarding Implementing legislation
We are concerned that the plan fails to address the
following important management and regulatory factors:
• The Plan does not include a mechanism to halt or reduce
captures if there is evidence that takes are unsustainable.
• The Plan provides no opportunity for objective and
independent monitoring and evaluation of the Plan. We
are concerned about possible conflicts of interests
for the managers of the Plan. It appears that the same
individuals whose available finances are dependent on
funds generated by the plan develop the quotas, conduct
the field research and, monitor populations and habitat
conservation.
• The Plan includes no mechanism for evaluating the
level of compliance for so-called “preserved lands.”
• The WBCA requires that the plan ensures that “the
use of the species is biologically sustainable and maintained
throughout the range of the species in that country
to which the plan applies (emphasis added)” (WBCA Sec.
106 (c) (1)(B)) yet the Plan does not regulate the capture,
hunting, and sale of individuals of this species in
areas outside of the management plan or within the clearly
significant “folkloric” trade.
4. Additional requirements under the WBCA
All range States are not effectively implementing the
CITES Convention as required by the WBCA.
In evaluating
proposals for trade, the WBCA requires that the Secretary
“consider the adequacy of regulatory and enforcement
mechanisms in all contries of origin for the species,
including such mechanisms for control of illegal trade”
(WBCA Sec. 106(a)(3)(B)) (emphasis added). A species
may only be included in the list of approved species,
“if the Secretary finds the Convention is being effectively
implemented with respect to that species because each
country of origin for which the species is listed is
effectively implementing the Convention...”(WBCA Sec.
106 (c)(1)). Congress’ intent in adopting these provisions
is made explicit in the Committee Report that accompanied
the bill to the House Floor. In that Report, the Committee
on Ways and Means explained that “[t]he point of considering
the adequacy of regulatory and enforcement mechanisms
in countries other than the country of origin is to
allow the Secretary to consider whether birds are being
smuggled from bordering countries into countries which
might be erroneously identified as countries of origin”
(102 H.Rpt. 749, Part 2).
Amazona aestiva is native to Argentina, Bolivia, Brazil
and Paraguay (Juniper and Parr 1998). At the April 2003
meeting of the CITES Standing Committee, the Regional
Representative for Central and South America and the
Caribbean presented a report (SC49 Doc. 24.3, Annex
2) concerning the illegal and unsustainable trade of
CITES-listed wildlife in Paraguay. The report included
a statement that illegal traders were moving specimens
of Amazona aestiva to Argentina and Brazil. Irregularities
included falsified biological information (on which
export quotas were based) and corruption within Paraguay’s
environment agency (SEAM-Secretaría del Ambiente) (González
2003). Paraguay recently adopted a voluntary moratorium
on exports of CITES-listed species (CITES Notification
No. 2003/058). The Notification requests neighboring
countries to be alert to “the possibility of unscrupulous
traders attempting to smuggle specimens from Paraguay
through their territory.” It identifies Amazona aestiva
as a species of particular concern in this regard. This
is precisely the risk Congress sought to guard against
in Section 106. Clearly, the Service cannot approve
the Argentine Plan as Paraguay is not effectively implementing
the CITES Convention.
The WBCA states that when making a determination under
the list of approved species, the Service “shall use
the best scientific information available (WBCA Sec.
106 (a)(3)(A).” More than 90 of the world’s preeminent
parrot scientists have declared their opposition to
the Plan stating that the harvest quotas are not based
on sound population dynamics (Bucher 2000) and that
the Plan provides no biological justification for the
quotas (APC 2000). We are concerned that, in the Proposed
Rule, the Service chose to ignore input from the independent
scientific community.
The WBCA
states that, in order for a species to be included in
the approved list of non-captive bred birds, a finding
must be made that the management plan “ensures that
the use of the species is biologically sustainable”
(WBCA Section 106 (C)(2)(B)). In addition, the WBCA
states that “Utilization of exotic birds that is not
sustainable should not be allowed” (WB CA Section 102
(4)). The proposed quotas are not sustainable. A brief
review of the Plan illustrates that the Plan does not
suffer simply from a lack of biological information
but that the development of the capture quotas is fundamentally
flawed.
As this would be the first application of its type to
be accepted under the Wild Bird Conservation Act, how
the Service judges and acts on it will set an important
precedent. Moreover, the Service explicitly acknowledged
the special status of Amazona aestiva in the final rule
promulgating the Section 106 regulations. After noting
Congress’ intent that “management plans for birds that
are becoming rare should be much more stringent that
those for birds that are very abundant and subject to
population control programs,” the Service explained
that:
For example, a sustainable use management plan for the
CITES Appendix II-listed Blue-fronted Amazon (Amazona
aestiva) which has declined in some parts of its range
would be evaluated more stringently than a sustainable
use management plan for the CITES Appendix III-listed
red-billed waxbill (Lonchura senagala) which is abundant
and widespread in its range (61 Fed. Reg. 2084, 2090
(Jan. 24, 1996)).
Given that
this is not only a precedent-setting application, but
one for which the Service has admitted the need for
greater care, we believe the Service must be particularly
stringent in assuring itself that the program actually
does meet the requirements of the Act before granting
Argentina's request. However, the supporting materials
provided by the CITES Management Authority of Argentina
fail, in our view, to provide these assurances. In light
of this fact, it would be manifestly inappropriate to
approve the application. In accordance with the dictates
of good science, good public policy, and the WBCA, the
application must be denied.
