White-faced saki
Pithecia pithecia
Here’s a primate with an unusual head. With its facial disk (white for males, gray for females), the white-faced saki lives in the north of the South American continent. They generally live in the lower levels of the canopy, feeding mainly on fruit, nuts, leaves and insects. Diurnal, these small primates live in pairs for life. However, this does not prevent them from forming small groups of up to 12 individuals. Unlike most other arboreal primates, the saki moves around by jumping from branch to branch.
