capuchin“The Lomas Barbudal Capuchin Monkey Project”

The Lomas Barbudal Monkey Project was founded in 1990 by Susan Perry, with the help of Joseph Manson and Julie Gros-Louis, for the purpose of studying social intelligence in the white-faced capuchin, Cebus capucinus. In the past 17 years of almost continuous observation, the Lomas Barbudal capuchins have become one of the most intensively studied wild monkey population in the world. Capuchins, a New World primate, are particularly good models for many human traits because they have developed many important features that warrant explanation (e.g. large brain size, social traditions, lethal coalitionary aggression, complex social relationships and social cognition, tool use, food sharing, extensive cooperation) independently of humans and the other great apes.

Capuchins are skilled extractive foragers, and social influence guides their adoption of particular foraging strategies. White-faced capuchins are known particularly for their propensity to develop unique, culturally variable bond-testing rituals. The Lomas Barbudal monkey project has focused its research most intensively on questions regarding social dynamics, communication, social traditions, and development.
