Wedge-capped capuchin

The wedge-capped capuchin (Cebus olivaceus), also called the Guianan weeper capuchin, is a medium-sized capuchin monkey found in northern Brazil, Guyana and Venezuela, where it dwells in tall primary forest and travels long distances during the day. It is named for a black triangle of dark fur on the forehead, and it has slightly longer limbs than other capuchins, which suits running and jumping through the forest canopy. Adults weigh about 3 kg, and males average about 30 percent heavier than females. Its diet consists mainly of fruits, invertebrates and other plant parts, with small vertebrates on rare occasions. Groups of 5 to 30 individuals follow a dominance hierarchy. The IUCN lists the species as Least Concern.
