Habitat
White-nosed sakis primarily inhabit the tropical rainforests of the Amazon Basin, including areas in Brazil, Guyana, Suriname, and French Guiana. They prefer the upper canopy of mature forests with dense vegetation for foraging and shelter. These monkeys avoid open areas and are typically found at elevations below 500 meters.
Diet
White-nosed sakis mainly eat fruits, seeds, and young leaves, with a particular preference for hard-shelled fruits that they crack open using their strong jaws. They also consume insects and occasionally flowers, foraging primarily in the treetops during daylight hours. Their feeding behavior involves moving in groups to locate food sources efficiently.
Behavior
White-nosed sakis live in groups of 10 to 50 individuals, typically led by a dominant male, and exhibit strong social bonds through grooming and vocalizations. They are diurnal and arboreal, spending most of their time in the forest canopy, leaping up to 10 meters between trees. These monkeys are territorial, defending their home ranges with alarm calls, and they often rest in the afternoon to avoid the hottest parts of the day.
Conservation Status
The IUCN classifies the white-nosed saki as Vulnerable due to habitat loss from deforestation and hunting pressure. Population trends are decreasing, with major threats including logging and agriculture expansion in the Amazon.
