Bolivian Squirrel Monkey
A fast-moving little monkey that travels in large troops through the southwestern Amazon canopy.

Artwork inspired by Cecilio Guzmán de Rojas
Bolivian Squirrel Monkeys have white facial masks, dark caps, yellow-orange limbs, and long balancing tails that are not used as grasping fifth limbs. Troops forage for insects, fruit, and other small foods.
In southeastern Peru, listen for rustling and soft calls moving rapidly through mid-canopy near rivers. Stay below rather than following off-trail; large troops need room to cross without being split by people.
