White-faced saki monkeys live in tropical rainforests up to 2,300 feet in southern and eastern Venezuela, in the Guianas and in northeastern Brazil. They are omnivores who primarily eat fruit. Saki monkeys are small monkeys native to northern and central South America. Sakis are diurnal (active during the day) and arboreal (they rarely descend from the tree canopy to the ground).
White-faced saki monkey behavior and facts
- White-faced sakis eat fruit, principally berries. They also forage for honey, leaves and flowers, and prey on small mammals and birds. They have been observed going into hollow trees to retrieve roosting bats. They tear the bats apart and skin them before eating.
- They prefer living in the middle levels of a forest, preferably one that is not flooded. They sometimes descend from the canopy to the shrub layer for feeding.
- Sakis move on all fours, but occasionally run on their back legs along horizontal branches. Their legs are much longer than their arms and are adapted for making long, downward leaps within or between trees. Sakis thumbs are pseudo-opposable, reaching partway but not fully to its other digits.
- Sakis sleep coiled on open branches like a cat.
- These monkeys are usually seen alone or in pairs; a family group is no more than five.
- In captivity they are silent but in the wild emit loud and penetrating calls.
