General Information

Where do they live? (Natural habitat)

White-faced sakis live in rainforests in Brazil, Guyana, Venezuala, Suriname and French Guiana. They are found in the lower canopy of the forest rather than high in trees.

How long do they live?

Approximately 15 years in the wild and over 20 years in zoos.

What do they eat?

White-faced sakis mostly eat fruit and seeds. They also eat leaves, flowers, insects and other small animals. They have strong teeth that they use to crush hard seed shells and peel fruit.

Zoo location

South American House.

Closest related species / sister species

Fun facts

Flying monkey

White-faced sakis are nicknamed ‘flying monkeys’ due to their ability to leap up to 10 meters from branch to branch.

Signature male trait

Only the males have the signature white faces. The female’s face is grey, brown or red.

Tail

The White-faced saki’s long tail is not prehensile like other monkeys. This means that they cannot use it to grab onto branches in the way that other monkeys do.

Family Life

White-faced sakis live in groups that vary in size from 4-12 individuals. It had been thought that they were monogamous (having only one mate at a time), but this is now believed to be the case only in zoos rather than in the wild. Adolescent siblings help with raising infants if they still live with their parents.
