Open encyclopedia reference
The Central American squirrel monkey (Saimiri oerstedii), also known as the red-backed squirrel monkey, is a squirrel monkey species from the Pacific coast of Costa Rica and Panama. It is restricted to the northwestern tip of Panama near the border with Costa Rica, and the central and southern Pacific coast of Costa Rica, primarily in Manuel Antonio and Corcovado National Parks. It is a small monkey with an orange back and a distinctive white and black facial mask. It has an omnivorous diet, eating fruits, other plant materials, invertebrates and some small vertebrates. In turn, it has a number of predators, including raptors, cats and snakes. It lives in large groups that typically contain between 20 and 75 monkeys. It has one of the most egalitarian social structures of all monkeys. Females do not form dominance hierarchies, and males do so only at breeding season. Females become sexually mature at 2+1⁄2 years, and males at 4 to 5 years. Sexually mature females leave the natal group, but males can remain with their natal group their entire life.
