The Pitheciine Action Group

The Pitheciines include some of the most unusual and enigmatic primates in the Neotropics. Several taxa are threatened with extinction, and for many we lack all but the most basic information.

The Pitheciine Action Group (PAG) exists to promote the effective conservation of the genera Callicebus, Cacajao, Chiropotes and Pithecia. Its main objectives are to coordinate and encourage research, act as a clearinghouse for information and resource sharing, and provide information to guide policy decisions.

Founded informally in 2005, PAG was launched officially at the Pitheciins: Ecology and Conservation symposium of the 2006 IPS Congress in Uganda. It has an Executive Committee of four and an established 25-member Coordinating Committee, which includes primatologists from all range countries.

PAG has launched a dedicated website at and an electronic newsletter (The Sapajou). Website resources will include key literature, theses and dissertations, photos and videos, recordings of vocalizations and maps of museum specimen distributions, as well as information on current and future projects and research priorities.

Current PAG activities include producing Evolutionary Biology and Conservation of Titis, Sakis and Uacaris, a 45-chapter, 82-author book to be published by Cambridge University Press, and — together with the Brazilian Environmental Protection Agency (IBAMA) — developing Action Plans for all the endangered Brazilian taxa.
