The World's Top 25 Most Endangered Primates- 2002

A recent report released by Conservation International (CI) and the Primate Specialist
Group of IUCN was finalized at the 2002 International Primatological Society meetings
in Beijing. It is a revision of their previously released "The World's Top 25 most Endangered Primates",
which indicates that about one out of every three primate species is currently
threatened with extinction.  This updated version suggests that Indonesia now exceeds
Madagascar and Brazil for the country with the most endangered primates.  However,
Madagascar, identified as one of the world's biodiversity hotspots, has 10 critically endangered
species, and 21 endangered species.  For the full report, please refer to the link at the bottom
of this message.

Each week, we will be featuring one of the 25 primate species in peril.  This is being
done in conjunction with Conservation International.  The fact sheets are compiled by
Sean Flannery at the WPRC Library and Information Service.

Buff-headed Capuchin (Cebus xanthosternos)

Photo Link:

Unlike most of the more than 30 types of capuchin monkeys that inhabit the New World tropics,
which are relatively common and abundant, this endemic species of Brazil's Atlantic Forest region is seriously threatened
with extinction. There are no reliable estimates of remaining populations, but the buff-headed capuchin is believed to be
declining throughout its restricted range primarily due to loss of forest habitat, as well as to hunting and live capture
as pets. Adult animals are relatively large (about 6 pounds) and provide sufficient meat to warrant the cost of a shotgun 
shell, while young animals are popular as pets. Surveys conducted in the early 1990s confirmed this species' restricted 
distribution in the eastern Brazilian state of Bahia (and possibly northern Minas Gerais), and its occurrence in 
the Una Biological Reserve and at least two biological stations. It has, however, been extirpated over a large part 
of its former range. Brazilian biologist Cecilia Kierulff of Conservation International, who has successfully translocated 
small, unprotected and non-viable groups of golden lion tamarins to form a larger, protected population, 
has recently embarked on a survey and census of Cebus xanthosternos. Her project is also receiving financial support 
from a number of European zoos at which this species is exhibited and has bred
