Guianan Weeper Capuchin

Open encyclopedia reference

The wedge-capped capuchin or Guianan weeper capuchin (Cebus olivaceus) is a capuchin monkey from South America. It is found in northern Brazil, Guyana and Venezuela. Cebus olivaceus is known to dwell in tall, primary forest and travel over long distances during the day. These primates are medium-sized monkeys with distinctive "wedge cap" markings on their head and slightly longer limbs than other capuchins for jumping through the forest canopy. Similar to other capuchin monkeys, the diet of wedge-capped capuchin primarily consists of fruits, invertebrates, other plant parts, and on rare occasions small vertebrates. They have also been known to rub millipedes against their fur, especially in the rainy seasons, as a potential means of mosquito repellent. Cebus olivaceus is a polygamous species that lives in groups of anywhere from 5-30 individuals with female-biased sex ratios. The group is organized according to a pre-determined hierarchal system of dominance for both males and females. Although biological lineage is less of a factor of dominance for males than it is for females, due to male migration between groups.
