The species
Cracids
are a family of large gregarious game birds made up
chachalacas, guans and curassows, many of which have
striking colours. Found only in the Neotropics, their
size makes them an ideal protein source for people living
in the region. Unfortunately, Cracids are not always
harvested sustainably, many are severely over-hunted
and their populations are plummeting rapidly throughout
their range. Depletion of their natural forest habitat
is another key threat to Cracids.
Chachalacas are the smallest members of the Family Cracidae.
There are a dozen species, all in the genus Ortalis.
Guans are the medium-sized members of the family, they
are also the most diverse, comprising 24 species. Curassows
are the largest of the Cracids with 14 species.
Group
overview
The
Cracid Specialist Group (CSG) was formed by Stuart Strahl
in 1990 under the supervision of the World Pheasant
Association, BirdLife International and the IUCN Species
Survival Commission. Today the CSG is Chaired by Dan
Brooks, with a number of Regional Coordinators that
help expand regional interest in conservation of these
species.
Among
the CSG's most important objectives is bringing the
Family Cracidae to the global attention of conservationists,
and to stimulate additional research and worldwide interest
in these endangered species.
One of the first goals of the CSG was to point out the
economic importance of the Cracids in the ecological
maintenance and preservation of Latin American forest
reserves. The CSG maintains its active network through
a series of workshops and symposia, a progressive publications
series, and through endorsing a number of field conservation
projects. In 2000, the Group published Curassows,
Guans and Chachalacas: Status Survey and Conservation
Action Plan which serves as a guiding tool
for the conservation of these fascinating birds.

Fernando González García - CSG Regional
Coordinator - Mesoamerica
Fernando
González García, a Mexican biologist,
studies the ecology, natural history and captive breeding
of the horned guan. This is the longest ongoing Cracid
research project, exceeding two decades.
Fernando first became intrigued by Cracids in 1980,
when he attended a national meeting of ornithologists
and conservationists in Xalapa, Veracruz, México.
"I learned about the precarious situation of the
Cracid family and especially of the horned guan. Habitat
destruction and illegal hunting had pushed the species
to the edge of extinction," he said.
Congress participants expressed grave concern about
the future of Mexico´s Cracids . My interest was
especially drawn to discussions about the horned guan
(Oreophasis derbianus) - one of Mexico's seven
Cracid species. The pavón, as it is known in
Mexico and Pavo de Cacho in Guatemala, is endangered,
restricted to the cloud forests of Guatemala and the
Mexican states of Chiapas and Oaxaca. It has been seen
in two regions of the Sierra Madre de Chiapas, the Reserva
de la Biosfera El Triunfo and Volcan Tacaná.
"My first visit to El Triunfo was in March 1981.
Each day I walked for eight to ten hours through thick,
foggy, moist woods looking for the guan. More than two
weeks went by before I found one, and I only saw it
for about 15 seconds. This made me realize that studying
the bird for a reasonably long period would be a challenge
and an adventure, considering its rarity, how difficult
it is to find in the natural habitat, and the scanty
information available," said Fernando.
Fernando's research has meant that much more information
now exists about the natural history of the pavón.
As well as studying the horned guan in the field, Fernando
started a captive breeding jointly with a colleague
and later with the Foundacion Ara in Monterrey, Mexico.
This project continues in collaboration with the Africam
Safari Zoo, in Puebla, Mexico and has succeeded in breeding
some guans.
Most of the investigations on the horned guan have been
carried out in the Chiapas state, focused mainly on
ecology and reproductive biology. A database of Mexican
bird sounds is now being developed, together with bioacoustics
training courses in the diverse states of Mexico and
some other Central American countries. Early versions
of the Mexican Bird Sound Library can be found at: www.ecologia.edu.mx/sonidos.
Sergio Luiz Pereira, PhD. - CSG Regional Coordinator
- Brazil
Sergio
has been working on the conservation biology and molecular
systematics of Cracids for almost 10 years. He has focused
his efforts in the lab to answer several questions regarding
the biology of cracids. He received a B.Sc degree in
Biological Sciences in 1994 from the Universidade Estadual
Paulista, Brazil, MSc and PhD degrees in 1996 and 2000,
respectively, from the Universidade de São Paulo,
Brazil.
Sergio's main interest in cracids originated from the
opportunity to apply genetic techniques in the conservation
biology of a group of endangered Neotropical birds.
He has evaluated the genetic variability of captive,
reintroduced and wild populations of Cracids. Sergio's
goal is to use genetic data as a tool to manage pairs
of cracids involved in captive breeding programmes and
evaluate to what extent they are losing their genetic
variability due to declining populations.
In collaboration with private conservationists and hydroelectric
power plants in Brazil, Sergio's team has successfully
released and established wild populations back into
areas where they were previously found. One good example
is the recovery of two species of guans of the genus Penelope in a reforested area in the state of
São Paulo. Also, in collaboration with colleagues
in Brazil and Canada, Sergio has solved some taxonomic
problems within the Cracid family. One of these was
the validation of the extinct-in-the-wild Alagoas curassows
(Mitu mitu), as a unique species, therefore,
deserving immediate conservation action. He and his
collaborators in Brazil also evaluated the genetic background
of a captive stock of this species to be used in a recovery
programme in the wild. Recently, Sergio has proposed
an evolutionary hypothesis for the origin of these birds
and established the genetic relationship between all
14 valid species of curassows, which will provide a
better background for future conservation actions. Sergio
is also the Portuguese Editor for the Bulletin of
the Cracid Specialist Group.
Sara Bennett Ph.D.
Sara
Bennett got "sucked into" the Neotropics by
an interest in the ecology of migratory birds and has
been pretty much "up to her neck in the swamp"
ever since.
For 15 years, she lived in a remote area of the Colombian
Amazon, studying flowering and fruiting rhythms of rainforest
trees and bird diversity patterns, painting, and taking
care of whatever orphaned life form fell out of the
sky (mostly infant monkeys confiscated from the illegal
wildlife trade). Then the FARC (Revolutionary Armed
Forces of Colombia) showed up, and that was the end
of that era, she said.
For the past three and a half years, with the support
of the Field Conservation Program of the Columbus Zoo
and Aquarium, Amacayacu National Park, the Instituto
Alexander von Humboldt, the Disney Zoo Conservation
Program, and the Abercrombie and Kent Global Foundation,
and to help implement the IUCN/SSC
Cracid Specialist Group Action Plan, Sara has been
working along the Colombian stretch of the Amazon River,
with the Amacayacu National Park and the indigenous
people who share jurisdiction for the southern part
of this important conservation area. This work began
as a straightforward investigation into the biology
of a little-known, intriguingly different, and endangered
Cracid species, the wattled curassow (Crax globulosa)
with a large team of local co-investigators. It has
resulted in an ongoing field experiment to see whether
the population will recover if it is not hunted and,
in the catalysis of programmes that are empowering local
people as leaders in the development of natural resource
management plans, community-based natural resource monitoring,
and research.
In a country notorious for violence and conflict, Sara's
goal is a "win-win" outcome, in which both
wildlife populations and humans benefit from local initiatives
to understand and experiment with the structure and
dynamics of the system in which they are keystone predators.
A popular book on the conservation and natural history
of Colombian monkeys illustrated, written (in Spanish),
designed by Sara and commissioned by the Instituto Alexander
von Humboldt (the government agency responsible for
development and analysis of the scientific aspects of
natural resources policy in the country) is currently
in press.
Bennett Hennessey
Bennett
Hennessey has been working on birds in Bolivia for the
last eight years, from the obligatory volunteer work
and co-guide (read tripod carrying) early years, to
field expeditions going where no scientist has gone
before, most recently. In 1997, Dan Brooks, CSG Chair
noted the strange disappearance of what was once a common
species of Cracid, the wattled curassow (Crax globulosa)
and Bennett's interest was piqued.
Here was a large curassow that had been last recorded
in Bolivia in 1937, and recorded before that as very
common. So what had happened? With support from the
World Pheasant Association, Bennett went to the closest
large town and started seeking local information. The
bird was a mystery, no information existed about it,
until one day, a 70 year-old former caiman hunter said
the magic word - Mamaco (the wattled curassow in Tacana
indigenous language). He led to other men, who in turn,
led to a series of villages close to the site where
the species was first seen. "Several trips were
made until finally, with the support from the Swedish
International Development Agency and the Wildlife Conservation
Society (WCS), we packed our tents, bought our food
and water purification tablets and headed off into what
would become Mamaco territory. Eight days later we were
looking up at a male perched in a tree along the Rio
Negro," said Bennett.
"This was big news, but now we really needed to
do something, especially as the species remains threatened
by local hunting. We thought it was important to talk
to the local communities along Rio Negro and through
the Chicago Zoological Society Board's Endangered Species
Fund and WCS support, we traveled back to the five main
communities on the edge of the wattled curassow's range.
In each community we presented the information we had
learned from elders and our expedition results. We asked
them if they would consider creating a hunting moratorium
on the species - which most did! And to leave a more
lasting message, we raffled Mamaco t-shirts off to the
communities. The t-shirts, with artwork of the male
and female wattled curassow serve as a field guide,
and an education and communication tool."
In August 2003, through the Weeden Foundation support,
Bennett and colleagues completed a preliminary census
of the species, finding it to have a healthy enough
population that simply needs protection, and not a complex
reintroduction programme. They also produced an educational
video of the species.
"We are now moving on to how we are going to protect
this wonderful animal. We have plans to conduct a workshop
with the local communities to discuss how we can protect
the species. In Bolivia we have many options, but we
want to find the most sustainable way to protect the
wattled curassow and secure its long-term future,"
says Bennett.
