NRN Advisory Board
Convenes in Panama


On the first and second of November
2004 The Peregrine Fund convened
the first ever meeting of the Advisory
Board (AB) for the NRN. The Advi-
sory Board to the NRN consists of ten
volunteers working with raptors in the
Neotropics and representing or with
an interest in Neotropical countries.
The members of the first NRN Advi-
sor Board are: Sergio Seipke, Sharon
Matola, Cesar Sanchez, Rick Watson,
Keith Bildstein, Jaime Jimenez, Marc
Bechard, Jorge Albuqurque, and my-
self the coordinator Cameron Ellis.
The objectives of the meeting
were to establish the Bylaws and
identify the direction, activities and

character of the NRN. Our first
order of business was to work out
a mission statement of the NRN.
After some tinkering we came up
with one modeled on a similar
and successful organization in
Asia, the Asian Raptor Research
and Conservation Network
(ARRCN): The NRN is a mem-
bership based organization aimed
to enhance the capacity and effec-
tiveness ofpeople working with
raptors in the Neotropics. Its
goal is to aid the research and
conservation ofNeotropical rap-
tors by promoting communication

Fall Raptor Migration
by Cesar Sanchez

Every year millions of birds escape the cold
weather of North America, and travel south
into the tropics where they spend sometimes
more than six months of the year, and rap-
tors are no exception. Around 30 species of
diurnal raptors are known to migrate
through the Americas. Some owl species
are known to migrate, although the informa-
tion available for the Neotropical region is
scarce.
Southward movements can be seen
as early as late August. The migration be-
gins with species such as Swallow-tailed
(Elanoidesforficatus) or Mississippi Kites
(Ictinia mississippienses) and it continues
until early December, when the most pre-
dominant migrating species are late migrat-
ing Turkey Vultures. Due to the large num-
bers of late migrating Turkey Vultures
(Cathartes aura), Broad-winged (Buteo
Platypterus) and Swainson's Hawks (Buteo
Swansoni), the majority of these movements
occur during October and November. These
species form large dense flocks of several
thousands of birds as they pass through nar-
row migration corridors in Mexico and Cen-
tral America. The migration routes cover a
wide variety of habitats including savannas,
tropical rain forests, and even cloud forest in
the top of mountain ranges; still, accurate
route information for individual species is
often poorly known or unavailable.
During the past years, strategically
placed raptor watch sites have been estab-
lished to monitor the movements of raptors
through the Neotropical region. The 2004
Fall migration marks the most recent chap-
ter in this continuing investigation. Raptor
counts were carried out in Mexico, Costa
Rica and Panama. Here, included are total
counts for the migratory season in Veracruz,
Mexico and K6koldi, Costa Rica.

Call for Future Articles
This is the first of the NRN's biannual Newsletter. The idea for this
newsletter was put forth at NRN Advisory Board meeting in Novem-
ber of 2004. For this reason we did not have a chance to call for con-
tributions from the broader membership of the NRN, and the articles
were written primarily by members of the Advisory Board. However,
this newsletter is a chance to share the projects and experiences of all
NRN members. If you would like to write an article for the next
NRN Newsletter please send it to me by June 27th 2005. Articles can
be about any subject so long as it pertains to the theme of the NRN,
and we encourage them to be light and easy to read. Please contact
me if you have any further questions or you would like to submit an
article.

The NRN Logo Comes to Life
By Cameron Ellis


Almost half a year ago the first
round of NRN logo artwork was
received with some amount of
dissent. The dissent was due
largely to the fact that whatever
bird was depicted in the logo, it
only represented the interests of
some among the roughly 140
members of the NRN. This dif-
ficulty is to be expected in a re-
gion as large and diverse as the
Neotropics, where no raptor ex-
ists to mirror exactly, impar-


tially, and uniquely the
Neotropical bio-geographical
realm. Indeed, the Neotropical
Realm means humid forests to
some, soaring mountains to oth-
ers, arid plains to still more, and
the list goes on.
We then expanded our
vision of the logo to include
several birds. Several birds al-
lowed some flexibility to ad-
dress the different habitats and
varied species of the Neotrop-
ics... but that approach diluted
the artistic and symbolic value
of the logos, and still, no matter
which birds were chosen, they


could not address the wide range efforts of people dedicated to the

Harpy Eagle Releases in Belize


Photo: Russell Thorstrom


by Sharon Matola

As the Belize coordinator for The
Peregrine Fund's Harpy Eagle
Restoration Program, it is good to
report that both captive bred birds
hard released in northwestern Be-
lize in early June of this year,
within the protected forests of the
Rio Bravo Conservation Manage-
ment Area, are doing well.
The female was reported
eating a Coati (Nasua narica), on
the 31st of October. The male has
yet to be noted hunting independ-
ently, but he has avoided the lodge/
research station area which is not
far from his release site.
The Rio Bravo hard re-
lease site has a robust prey base.
Deer, peccary, various birds and
reptiles are plentiful and the feel-
ing is optimistic that the released
eagles will thrive in this area.
In December, the project
received a visit from ornithologist
and author of the Birds of Belize,
Dr. Lee Jones. He is also part of
an effort to assess the prey base
along a river system which cuts
through this tropical forest.
Another female Harpy
captive bred and released is hunt-
ing independently, however, in a
forested area south of the Maya
ruins of Caracol, in a hard-to-
access area. This highly-karstified
region of Belize makes it difficult
to trap the bird for transfer to the
hard-release site, and there is some
concern about her being too close
to the Guatemalan border where
potentially dangerous conflict with
people could occur.
Posters featuring an imma-
ture Harpy Eagle are given out
continuously in Belize, and a few


have been posted in the Darien
region of Panama as well. The
Belize Zoo is working to develop
a t-shirt to popularize the Harpy
Eagle in Belize. Plans for the
4th Hoodwink the
Owl children's
book about the
Belize Harpy Ea-
gle Restoration
Program are now
being initiated and
it is projected that
this Harpy Eagle
conservation pro-
gram will have a
heightened profile
and receive much
attention, both in
Belize, and outside
the borders of this
nation.

...NRN AB Meeting

and collaboration among biologists,
ornithologists, raptor enthusiasts and
other conservationists working in the
Neotropics.
After establishing the NRN
Mission Statement and addressing the
structural aspects of the NRN, the Ad-
visory Board went on to identify the
limiting factors for raptor research and
conservation in the Neotropics.
Not surprisingly, funding and
training were named among the pri-
mary limiting factors for researchers
and conservationists. To address this
and other issues related to the effec-
tiveness of scientific and conservation
work in the Neotropics, the NRN Ad-
visory Board outlined a series of pro-
jects in the NRN Bylaws, the govem-
ing document of this fledgling organi-
zation.
The NRN Bylaws identify five
organizational projects and a flexible
capacity to engage in further scientific
and conservation oriented projects.
The Organizational Projects make up
the core of activity for the NRN, they
are: An NRN List-server, a periodic
Neotropical Raptor Conference, an
NRN e-Newsletter, an NRN webpage
and an updated guide to the NRN
Neotropical Raptor Research and Con-
servation Priorities. The Bylaws pro-
duced at the recent NRN-AB meeting
also include a capacity to directly en-
gage in scientific and conservation pro-
jects, as they are approved by the Ad-
visory Board and in keeping with the
NRN Mission Statement, these are the
NRN Scientific and Conservation Pro-
jects. Check out the website for a
more in depth look at the different as-
pects of the NRN.
The final activity of the NRN-
AB meeting was to begin planning for
the next Neotropical Raptor Confer-
ence. It will be held in June of 2006 in
Iguazu, Argentina. An article in this


newsletter deals specifically with
the conference and preparations.
See pages 7 and 10.
Overall, the meeting was a
success and as coordinator of the
NRN it is a thrill to work with the
Advisory Board as well as the
broader membership of the NRN.
This recent meeting has given struc-
ture and commitment to what began
as a simple notion at the 2002


Neotropical Raptor Conference
and Harpy Eagle Symposium. The
idea behind the NRN is collabora-
tion, and we are committed to
wielding the NRN in such a way
that it best benefits all members.
So please, do not hesitate to con-
tact me for any for any reason with
questions or suggestions, we are
working for you and we would like
to hear how we can do better!

The 2006 Neotropical Raptor Conference

and Symposium on Raptors of the Southern Cone


Today, considering worldwide con-
cem over threats to the environ-
ment, and considering the large ar-
ray of species and habitats included
in the Neotropical region (here de-
fined as all Latin America and the
Caribbean) it is not surprising that
Neotropical conservation issues fre-
quently reach the world stage. The
immense diversity of habitats in the
Neotropics are home to many of the
world's most impressive raptors,
including the Andean Condor (the
world's largest flying bird), the
Harpy Eagle (possibly the world's
most powerful bird of prey), rare
falcons and owls, and many species
that are still unstudied. For centu-
ries the raptors of the Neotropics
have sparked the enthusiasm of
naturalists, falconers, scientists, and
other conservationists worldwide.
Even prior to that, they had promi-
nent roles in the myth and social
fabric of Pre-Columbian cultures.
However, raptors are more
than just interesting and charismatic
animals. They are important com-
ponents of ecosystems, and at the
top of the food chain they are excel-
lent indicators of environmental
health. Long before the forests are
clear-cut and lost or a contaminant
precipitates extensive environ-
mental harm, symptoms of a dam-
aged ecosystem often appear first in
the animals at the top of the food
chain. Peregrine Falcons alerted the
world to the dangers of the pesticide
DDT, and recently a crisis facing
three species of Gyps vultures in
Asia has uncovered the first ever
known case of a pharmaceutical
drug causing widespread environ-
mental impact. Raptors have been
likened to the 'canary in the coal-


miner's cage,' they provide us with
an early warning of declining envi-
ronmental conditions and ecosystem
health. As such, they are uniquely
valuable animals and if properly
executed, raptor research and con-
servation can be an important tool
for expanding knowledge and our
protective capacity of Neotropical
biodiversity.
Encouraged by positive re-
sults and enthusiasm among atten-
dees of the first Neotropical Raptor
Conference, held in Panama City,
Panama in 2002, The Peregrine
Fund helped establish the Neotropi-
cal Raptor Network (NRN) to en-


hance the research and conservation
capacity of Neotropical raptors and
provide for regular Neotropical Rap-
tor Conferences every four years.
Since its inception, the NRN
has become a unifying element for the
raptor research and conservation com-
munity across the Neotropics; and as
a young organization we are now
gearing up for the Second Neotropical
Raptor Conference, to be held in
Iguazu, Argentina on June 11th-14th
2006. The Neotropical Raptor Con-
ferences are of great importance for
sharing information and ideas, and
establishing working relationships
between scientists, raptor enthusiasts,

policy makers and other conservationists
working in the Neotropics. Due to its loca-
tion and focus, this conference will be of
singular importance to the issues, species
and habitat of South America and the South-
ern Cone in particular.
The Second Neotropical Raptor
Conference is a collaborative project, coor-
dinated by the NRN and sponsored by The
Peregrine Fund (USA), the Sheraton Inter-
national Iguazu Resort (Arg.), Aves Argen-
tinas/AOP (Arg.), Hawk Mountain Sanctu-

200 professionals and students from
throughout the Neotropics and around the
world.
Further support will be central to
the success of the 2006 Neotropical Raptor
Conference. We are currently offering sev-

SAICR I: First Argentine Symposium

on the Investigation and Conservation


of Raptors

In the last 10 years we have been
fortunate to see a notable prolifera-
tion of investigators and conserva-
tionists working with raptors in
Latin America; and scientific con-
ferences have proved to be among
the best means to encourage interac-
tion and promote communication
between those scientists and conser-
vationists.
The first Neotropical Rap-
tor Conference (NRC) and Harpy
Eagle Symposium, convened by The
Peregrine Fund in Panama City,
Panama, in October of 2002, was a
significant moment in the history of
collaboration and communication
between investigators and conserva-
tionists of Neotropical raptors. Ar-
gentina had a regrettably small pres-
ence at this important conference;
however, this country is actually
home to a large number of phe-
nomenal people actively dedicated
to this area of study and conserva-
tion.
In light of this strong group
of people, and with the goal of for-
malizing a community dedicated to
the conservation and investigation
of raptors in Argentina, we cele-
brated in La Plata, Buenos Aires, the
First Argentine Symposium on the
Investigation and Conservation of
Raptors (SAICR I) on the first and
second of October 2004. This event
was attended by more than 100 peo-
ple, among them researchers, con-
servationists, students, falconers,
directors of NGO's, as well as resi-
dents of Chile, Brazil, and Uruguay.
Twenty six oral presenta-
tions were given in sessions accord-
ing to subject matter, these presenta-
tions were complimented by five
thematic tables (discussion groups
and theme-specific workshops) and
three moderated debates. The de-
bates addressed relevant issues such


by Sergio Seipke

as the creation of an Argentine NGO
bringing together people working in
fields related to raptor research and
conservation, the frequency for the
SAICR conferences and the possibil-
ity of hosting the next Neotropical
Raptor Conference in Argentina in
2006.
The SAICR I produced
strong results and has laid a founda-
tion for future work: SAICR I pro-
moted direct communication between
researchers, students, conservation-
ists and other related people; it initi-
ated the creation of a national organi-
zation; it agreed to a two year fre-
quency of SAICR meetings; and fi-
nally it has put together a great at-
mosphere for sharing experiences.
All the attendees of the conference


received a Proceedings Book that
includes extended abstracts of each
presentation, these proceedings are
currently out of stock, but soon will
be converted to PDF and available on
the internet.
The first SAICR made an
indelible impression on those who
participated in it. It can be said that
the 'raptor community' of Argentina
acquired a solid and optimistic vision
of itself, one that was previously al-
most non-existent. It was, without a
doubt, proof of both the capacity of
its participants and the relevance of
the field.
Perhaps one day in the not
too distant future every country in the
Neotropical Realm will celebrate its
own raptor conference. In each
country, and in the Neotropics as a
whole, that day will be a triumph for
both the people who dedicate their
energies to the understanding and
conservation of raptors, and a tri-
umph for the birds themselves.

Newsletter of the
Neotropical
Raptor
Network


June, llth-14th


Location:

Iguazu,

Argentina


The Neotropical Raptor Network
invites you the Second Neotropi-
cal Raptor Conference, with a
Symposium on Raptors of the
Southern Cone. Join scientists,
conservationists, resource manag-
ers, falconers, representatives of
zoos, government and non-
government organizations and
other persons and institutions with
an interest in the research and/or
conservation of birds of prey in
Latin America and the Caribbean
to participate in a meeting to
share knowledge, interests, and
concerns and help develop a net-
work of practitioners in the fields
of raptor conservation, research,
captive breeding and falconry.
The meeting will include
a symposium dedicated to re-
search and conservation of raptors
of the Southern Cone, invited
speakers on raptor biology and
conservation, contributed papers
and posters on raptor biology and
conservation, workshops (some
still open to suggestion) pertain-


ing to raptor research and conserva-
tion, as well as a host of social activi-
ties and the constant lure of the Iguazu
Falls and National Park.
This conference will mark
four years since the first Neotropical
Raptor Conference held in Panama
City, Panama in October 2002. The
Advisory Board to the NRN chose
Iguazu, Argentina for several rea-
sons. Among them the NRN and the
NRC are for all people working with
birds of prey in the Neotropics, the
biogeographical region that extends
from Mexico to the end of Tierra del
Fuego. Argentina brings this confer-
ence across the equator and closer to
many of its members... and species!
Argentina and the Southern
Cone were also identified as regions
with a burgeoning population of en-
thusiastic individuals entering the field
of raptor biology and among the goals
of the NRN is to empower this grow-
ing potential. Argentina's varied land-
scapes and climates, from sub-tropical
to sub-Antarctic, offers a wide range
of habitats inhabited by many species
and an important opportunity to ad-
dress aspects of Raptor biology and
conservation in the Neotropical realm,
outside the tropics.
Iguazu is on the border with
Brazil and Paraguay, it constitutes a
part of the Atlantic Forest, a threat-
ened biome which harbors several
species of raptors, some of which are
rare endemics. The Mantled Hawk


(Leucopternis polionota) featured in
the conference image are among the
most rare and threatened raptor spe-
cies in the Americas.
...and, of course, Iguazu
Falls are a world renowned tourist
destination that absolutely everyone
with a passion for our natural world
must experience!
