The Pitheciine Action Group (PAG) exists to promote the study and effective conservation of the genera
Pithecia, Chiropotes, Cacajao and

Sakis, cuxiús (or bearded sakis), uacaris and titi monkeys
Tropical forests are disappearing at an alarming rate. It is estimated that
during the 1990s an average of 15.2 million hectares were lost per year.

Most non-human primates depend on forests to survive. More than 90% of these primates are located in tropical regions. Tropical forest destruction and fragmentation are now among the greatest threats to the future survival of many primate species.

Sakis, cuxiús (or bearded sakis), uacaris and titi monkeys belong to group of primates called the pitheciids. They are Neotropical primates that specialize to different degrees in seed predation. Over the last couple of decades we have started to accumulate some knowledge about these unusual primates but still have much to learn.

Unfortunately several members of this group are now threa
tened with
extinction and so one of our key tasks now, is to understand how we might be able to help preserve these unusual animals.

For the 2006 International Primatological Society's conference, we organized a symposium to collect together professionals who work with these primates to share knowledge and plan for future conservation.  As a result of the symposium, the Pitheciine Action Group (PAG) formed. We hope that PAG will allow for increased communication between researchers, identification of areas of greatest research need, and plans for concrete conservation actions.
We are pleased to announce the publication of Evolutionary Biology and Conservation of Titis, Sakis and Uacaris, a 36-chapter, 82-author book published in 2013 by Cambridge University Press. 

book brings together an international group of scientists who study these species. The book is dedicated to the memory of Liza Veiga.

We welcome and encourage people with interests in the behavior, ecology, and conservation of primates to use the resources on this site.
