The bearded saki lives in the tropical forests of South America, French Guiana, Suriname and Brazil.
Least concern (LC)
This tree-dwelling species rarely comes down to the ground. It is found in colonies of around sixty males and females who then divide into subgroups in order to look for food.
Possessing good balance, the bearded saki has nimble hands, the thumb and index of which can move away from each other, ensuring good grip when it grabs the branches.
The bearded saki practises “social resting” and spends long periods of time alongside other sakis to groom themselves. These positive types of behaviour between males are characteristic of the species, whereas interactions between males and females are rare.
