ZIM Andean Cordillera
The first registered report of a
Harpy Eagle (Harpia harpyja)
west of the Andean Cordillera in
Ecuador occurred in 1970. Since
then searches for a nest in the area
have been made without any suc-
cess. The humid forests on the
northwestern coast of Ecuador are
threatened due to exploitation of
timber, an economic resource for
the indigenous and Afro-
Ecuadorian communities living in
the forest. Nevertheless, despite
this substantial pressure and loss
of habitat, for the first time in
South America, we discovered
an active Harpy Eagle nest in the
north of Esmeralda Province, in

The NRN invites you to visit and become part
of the Global Raptor Information Network
GRIN.asp) a new tool implemented by The
Peregrine Fund. This virtual site is building-up
a raptor database, including distribution, popu-
lation state, bibliography and researchers who
have published or have knowledge of any rap-
tor species. Among other options, you can
access species lists by zoogeographic zone,
country, or search for related species accounts.
Furthermore, those people involved in the
study or conservation of raptors can access
your information via a personal page, which
displays their interests and research or conser-
vation issues. The goal of this is to forge an
interactive searchable database of raptor re-
searchers and conservationists.

western Ecuador. Although limited, d.
to the youth of the juvenile, the data IlI. il
we have recorded are the only that e i
at this moment for the species on Ili
western flank of the Andean Cordille!.
The discovery of an active Harpy E.,._c K
nest on the western flank of the Ecuad.i -
ian Andes is a first, not only in the ,n.,iiu-
ral history of Ecuador but of all Sou.il
The nest was found when a commuii-.
member was searching for gold :!i .
nearby valley, where the nest was I.'-
cated. He observed the adult female .i'n
the juvenile when the latter was approxi-
mately one month old and reported his finding in the community.
The area is promising enough that some biodiversity investigation
had already been made.
With some intermediates, this information came to SIMBIOE
(Society for the Research and Monitoring of Ecuadorian Biodi-
versity) and we have begun monitoring the eagles in this area.
The nest is in a 12,000 hectare area of continuous humid tropi-
cal forest. The climate is equatorial, with an average tempera-
ture of between 23 and 26 degrees centigrade. It receives an
average precipitation of more than 3,000 millimeters. The pre-
cipitation here always exceeds the temperature so there is no
dry season, nor any physically dry days. The altitude varies
between 200-220 meters above sea level. The distance of the
nest from the closest community (with population over 300
people) is 4.82 kilometers. The culture in this area is Afro-
Ecuadorian and their activities include agriculture, forest prod-
ucts, artisan goods and ecotourism.
Similar to the nests on the eastern slope of the Andes, the pair
used a large tree to construct the platform of their nest, at 30
S meters above the ground, in a depression in the ground. The
tree species was a "carra" (Huberodendron spp), a species used
for woodworking and 84 cm in diameter.
The presence of invasive groups on the community land where
the studies are being developed has made it difficult to con-
tinue the juvenile through his dispersal period, the conflict has
Made the area unsafe for monitors. Unfortunately, they were
unable to confirm data dispersal data for this unique juvenile
Harpy Eagle on the western flank of the Andean Cordillera.
A juvenile of approximately one year and three months was the
occupant of this nest. During the eight months following we
were able to data on its diet and behavior. We estimate the
date of birth to be around December of 2003. During eight
months we were able to observe the juvenile only 60% of the
time was spent looking for it, the rest of the time it spent out of
our sight. This is normal for a bird of this age, taking into ac-

List servers are a cheap, practical and easy way to communicate
info throughout a broad audience of people interested in a similar
topics. One of the primary list server types is operated on Yahoo!
Groups. In this article we will go over the characteristics of the list
servers dedicated to raptors in the Neotropics. The messages on
several of these list servers are open to pubic viewing, while on
others it is necessary to a member in order to view the postings.
Although you may possibly be subscribed to some of these list serv-
ers, I doubt you are subscribed to them all; so I am including the
websites and email addresses for each list server. I hope this brief
review will be of help to you.
NEOTROPICALRAPTORS is the name of our own list server, the
list server for the Neotropical Raptor Network "The NRN is a mem-
bership based organization aimed to enhance the capacity and ef-
fectiveness of people working with raptors in the Neotropics. Its
goal is to aid the research and conservation of Neotropical raptors
by promoting communication -
and collaboration among biolo-
gists, ornithologists, raptor en- '
thusiasts and other conservation-
ists working in the Neotropics. "', *
The list-server was created by I
the Advisory Board to the
Neotropical Raptor Network in
October of 2004 and became
active on the 15th of November V'
of the same year. New members
are continuously subscribing and :
it currently has a membership of
about 165 people and organiza-
tions. The messages from this '" .

Other list-servers that address Neotropical Raptors include:
FORORAPACES. Miguel Saggese and Lito Campos, both from
Agrentina, created the group on the 9th of August 2001. It is her-
alded "A meeting spot for enthusiasts and studi-
ers of raptors." The official language of the Photo: Jaime Jimenez
list-server is Spanish, although there are also
messages in Portuguese and other languages. Most of the subjects
discussed include distribution, taxonomy and identification of rap-
tors. There are also announcements regarding new literature,
courses, conferences and employment opportunities. In the first
half of 2005 it had an average of 21 messages per month. It cur-
rently has about 130 subscribed members, the majority of them

FALCOARIABRASIL is a "Group for all those who want to discuss
falconry is a positive and democratic manner." It was created on the
25th of October 2005 by Samuel Ferreira from Brazil. The official
language of the list-server is Portuguese, but there are also messages
in English and some in Spanish. The group of more than 160 mem-
bers receive a weekly summary of falconry news from around the
world and a synthesis of the issues discussed in the principal fal-
conry discussion groups. Many of the messages speak in a friendly
and informal manner of experiences of falconers, including the man-
agement and captive breeding of Neotropical raptor species. In the
first half of 2005 the members of this groups received and average of
300 messages per week! (But don't be scared away, its also possible
to receive jus the daily digests.)
Although not restricted to the
b Neotropics, these other list-servers
might also be of interest:
SATELORN. This list-server has 428
Smemebers and it was created on the
28th of September of 2001 by Bernd-U
Meyburg (World Working Group on
i Birds of Prey), to help disseminate
information on satellite telemetry tech-
niques in ornithology and the results
.. of their use in research for researchers
and other interested in the publication
i of scientific papers on the subject.
RAPTORCARE was created on the 4h of April, 2004. Is has 242
members that discuss injuries and sickness of wild and captive rap-
tors, as well as aspects of captive management issues such as diet
and training. It is of singular importance to veterinarians and
RAPTORRESEARCHCONSORTIUM is a list server restricted to
graduate level researchers with an interest in raptors. The group
helps disseminate information, news and opportunities among the
roughly 90 members world wide.

Workshop on Raptor Census
Techniques at the II NRC
Keith L. Bildstein, Marc J. Bechard .
& Sergio H. Seipke
The Objective is to provide committed students and young research-
ers with insights into techniques currently use survey and monitor
raptor abundance, distribution, and habitat use, and to train them in
these techniques through a "hands-on" experience in the field. The
workshop will focus on major types of survey techniques applied -..
both open habitats and forest, and will consist of a half-a-day lectu: c
session, together with two days of field work in savannas and grass-
lands in south Misiones and north Corrientes (Argentina).
Lectures will include (1) forest raptors survey techniques: ForeI
vegetation structure and its implication on raptor detectability. Ec-
havior and advertisement in forest raptors. Point counts from vantage
points (soaring raptors). Pre-dawn auditory counts (under-stor-.
raptors). Acoustic luring. Comparison among different techniques
Combining methods. Data collection. Analysis. Presentation ..!
results. Open-habitat raptors census techniques: Vegetation ard i
topography and their effects on detectability. Time of year and time
of day and their effects on detectability. Size and behavior of the
species involved and their effects on detectability. (2) Road survey f L
methods, including species counted, types of data collected. (3) Sur-
vey Data management, analyses, and interpretation. Presentation and
publication of results.
Field work will emphasize practical aspects of survey procedures I
and will be carried out after the conference. Road surveys from
moving vehicles will be conducted along paved and dirt roads in
southern Misiones and northern Corrientes.
Materials. Instructors will send copies of required readings in pdf
files to attendees, and will provide counting materials (sheets, pens,
notebooks, etc.). Transportation, meals, and housing during field
aspects of the workshop will be covered by the Hawk Mountain
Sanctuary Attendees should bring their own binoculars.

As part of the II Neotropical Raptor
Conference that will take place in
Iguazu, Argentina on the 11-14 of June,
2006 we are coordinating a workshop on
the regulation of falconry.
There are thousands of practicing falcon-
ers from many different parts of the
world, and currently there is a notable
increase in interest for the sport in areas
with little history of it, such as Latin
That fact makes it necessary to provide
adequate regulation in these areas, so that
it is practiced seriously and ethically, re-
specting the applicable national and inter-
national laws while assuring that its prac-
tice does not have negative impacts on the
populations of wild birds that are used in
This workshop intends to share informa-
tion, points of view and experiences that
contribute to the development of funda-
mental approaches to falconry legislation
that are in keeping with legal regulations
and the conservation of nature.
The workshop will be divided into two
parts. The first will consist of presenta-
tions on diverse issues by experts from
different countries (USA, Mexico, Spain,
Argentina, Brazil? etc) and it will include
baseline information and considerations for
the attendees, especially those in whose
countries the legal framework for falconry
has not been fully developed or it could
use renovation. The second part of this
workshop will be a case study of Argen-
tina, where the current falconry situation
will be discussed and considerations for
the development of a legal framework will
be made. Although this case study focuses
on Argentina, it will undoubtedly have
bearing on other Latin America countries.
We think that this exercise will set up in-
teresting information bases and provide a
useful set of tools to all those interested in
falconry and the sustainable management
of natural resources. Also, this forum
along with the large number of experts,
managers and enthusiasts involved with
raptors that will attend this event will make
for an excellent opportunity to develop
contacts and discuss pertinent issues.

Letter From Brazil
I must start this message saying that I am very happy and honored to be in contact
with the Peregrine Fund and that I admire its work immensely. I hope our center is
someway a bit like you when you started back in the seventies: in small beginnings,
but will grow....
CENAR Centro Nacional da Ave de Rapina. CENAR was a dream come true. All
my life I had wanted to work with raptors. I have a big passion for these birds and a
few years ago, I made a drastic change in my life. I sold everything I had in the big
city life and left the rat race for good. I bought a small hotel in a beach paradise and
started the center aiming helping those that nobody helps here in the country. The
first aim was to do rehabilitation work, founding the first raptor center in the coun-
try. As we started our work here the spectrum of our work somehow broadened.
Do you remember when I first contacted you? I didn't have any support. Today our
work is getting some visibility and some companies are starting to help. That will
give us a new kick and I hope our work will get a new rhythm...
CENAR is not a commercial breeding center like CEREFALCO from Fredy and
Carlos or ENFALCO from Ronivon. We want to be a Raptor Center. We are a pro-
ject that belongs to a NGO called AMAR Ave da Mata Atlfntica Reabilitada
(Rehabilitated Bird of the Atlantic Rainforest)
We have three primary lines of work :
1) Rehabilitate and reintroduce the raptors that pile up in horrible conditions in
the state general rehabilitation Centers
2) Promote environmental education using birds of prey.
3) Reproduce and reintroduce rare birds of prey that are mentally or physically
incapable of returning to the wild.
I am also sending the logo of our project (CENAR). The logo of our NGO (AMAR)
has the silhouette of a Harpy eagle, which shape was
taken from a picture of a Harpy Eagle The Peregrine
Fund has in Panama.

With an impressive 940 members RAPACES-IBERICAS is
the giant of raptor list-servers. It was created in June of
2004, for the "Exchange of observations, news, informa-
tion, ideas and proposals on the observation, study, manage-
ment and conservation of diurnal and nocturnal birds of
prey on the Iberian Peninsula, Balearic Islands and parts of
northern Africa." It represents the maximum potential that
these list-server can reach.

Whatever the language, number of members and number of
messages per month (or day!), all these list servers serve the
common goal of putting as much possible information and
expertise in reach in an efficient and effective manner. Of
course maintaining a high quality of information discussed
is a responsibility shared by the members.
One of the main advantages is that these list servers are
free. It is also remarkable the quickness with which the
messages reach all members (a matter of seconds). The
moderators, those who configure and manage the discussion
groups, have interesting management options, including
options that allow the mailing of attached files such as: pho-
tos, sounds, video, PDFs and electronic newsletters. The

count that the juvenile's development is centered on the explora-
tion of its parent's territory as a step towards dispersal.
Of the time we were able to directly observe the bird, 85% of its
time was spent perched on trees close to the nest (under 150 me-
ters), preening and jumping between branches. The preferred
perching sports were always on the highest branches of the trees.
The prey remains demonstrated that the majority of its diet was
composed of Two-toed Sloths i .li.,.. -"< hoffmani), although
there were also reptiles, birds and Three-toed Sloths j ,i,/1 ...I
At less than 200 meters from the tree, in July of 2004, a Spizaetus
