A group of Capuchin Monkey can move 1.5 to 3.5 km each day. Groups sometimes meet and may defend their territory by chasing each other. Adult males' job is to defend the group from predators and other monkey groups. Adult females help them participating in the chase.

Capuchin Monkeys are very vocal animals that scream, whistle and bark. In this way, they call each other in order to maintain contact and may express their dislike if someone or something disturbs them.
