Red-backed squirrel monkey  (Saimiri oerstedii)

The black crowned subspecies has a restricted range along the Pacific coast of the Puntarenas province in south-western Costa Rica, and in Chiriqui and Veraguas provinces, northwestern Panama (2).

The grey crowned subspecies is found in south-western Costa Rica where it has an even more restricted range, of only 210 km², on the Pacific coastal forests of Quepos (1).

This species mainly lives in lowland scrub forest (2), although it also inhabits humid tropical forest, mature upland forest, river edge and mangrove forest (1).
