Habits and Lifestyle
Monk sakis are shy and wary animals. They are totally arboreal, living high in the trees and sometimes descending to lower levels but not to the ground. They generally move on all fours but may sometimes walk upright on a large branch and will leap across gaps. They are social and diurnal creatures. During the day, they move in pairs or small family groups spending most of their time feeding. One of the main forms of socializing between the family members is allogrooming (social grooming). Monk sakis communicate with each other with the help of different vocalizations. Adults recognize each other by using highly specialized vocalizations. To express aggression Monk sakis use squeaks, whistles, trills, barks, grunts, and roars.
