Abstract
We report observations of intergroup interactions from a free ranging group of the endemic and threatened Beni titi monkey (Plecturocebus modestus). Our observations over the course of one study year suggest that competition for food resources is the main reason for most observed intergroup encounters (n = 64), including aggressive interactions (n=28). Additionally, threats to group integrity, such as potential loss of members, might promote very aggressive encounters, including three fights observed between adults of neighbouring groups. We provide new information on the intraspecific relationships for these endemic primates related to their use of space and food resources.
