White-faced Saki

Pithecia pithecia

Did you know?

  • White-faced sakis are a part of the Pitheciidae family, which they share with titis, uakaris, and other saki monkeys.
  • They are also known as flying monkeys and pale-headed saki monkeys.
  • They live in forests in northern South America.
  • Thanks to their sturdy canine teeth, white-faced saki monkeys can easily crack open the hard shells of nuts and seeds – even brazil nuts.
  • A female gives birth to one baby at a time.


White-faced saki are dramatic when they feel threatened. They fluff up and vigorously shake their body hair, then stomp their feet in an arched-back posture. They also are a vocal species, and duets between a male and a female help mark territory and strengthen their social bond. Due to their sturdy canine teeth, saki monkeys can easily crack open the hard shells of nuts and seeds—even Brazil nuts!

Young and Family

White-faced sakis live in small family groups. After an average 146-day pregnancy, females give birth to one brown infant. At two months, young males begin changing color from brown to black with white faces. Females remain brown into adulthood.
