Central American squirrel monkey

The Central American squirrel monkey (Saimiri oerstedii), also known as the red-backed squirrel monkey, is a squirrel monkey species restricted to the Pacific coast of Costa Rica and the northwestern tip of Panama, primarily in Manuel Antonio and Corcovado National Parks, and it is the only squirrel monkey occurring outside South America. It is a small monkey with an orange back and a white and black facial mask, living in lowland forests in large groups of 20 to 75 with one of the most egalitarian social structures of all monkeys. It eats fruits, other plant materials, invertebrates and some small vertebrates. Its population fell sharply after the 1970s because of deforestation, hunting and capture for the pet trade, and the IUCN listed it as endangered as of 2021.
