Monkeys are fascinating creatures known for their intelligence. One of them is the White-faced Saki, also known as Guianan Saki and Golden-faced Saki. These species are counted in the New World Saki monkey.

It is to be noted that these species can be found in French Guiana, Brazil, Suriname, Venezuela, Guyana and Suriname. They most evidently live around 14 years in their natural habitat and have been recorded to live up to 36 years in captivity.

In this region, the white-faced sakis are common in the highland and lowland rainforests that occur in the Cuyuni basin between the Caron and Orinoco rivers.

Although white-faced Sakis are arboreal creatures and are specialists in swinging from tree to tree, they are also considered terrestrial when foraging.

Notably, they sleep in trees, highly elevated from 15-20m, and they use leaves to shelter them from weather and flying predators.

Further, these Sakis live in the understory and lower canopy of the forest and mostly feed on nuts, seeds, fruits and insects. These animals need enough fruit-bearing trees and watering holes in both dry and wet habitats.

Their population is still unknown; their weight exceeds 1.9-2 Kg, and their length is up to 33-38 cm.

Physical appearance- White-faced Sakis

White-faced Sakis belong to the group of New World monkeys. Their small bodies are contrasted by long and heavily-haired tails. Otherwise called ‘Guianan Sakis’, these primates have powerful bodies and strong muscles on their legs, making them excellent jumpers.

It is to be noted that these animals exhibit sexual dimorphism: males are distinguished by black overall colour and buff-furred faces, while females have significantly lighter coasts with bright patches that extend from each eye to the chin.

In captivity, female white-faced jays have an ovarian cycle of approximately 17 days and a gestation period of 20–21 weeks. They breed once a year in the spring and only have one offspring.

Unlike howler monkeys, these animals do not have grasping tails and cannot grasp objects with their tails.

As per the study of Shawn M Lehman, a South American scholar stated that their group number can span from 2-12 group members, with higher numbers typically occurring in Guyana and South America.
