Habits and Lifestyle

Panamanian night monkeys are arboreal and nocturnal creatures. During the day they sleep or just rest in tree holes or in beds made of leaves between the branches. At night they spend most of their time foraging for food and move around on their four legs. They also can leap and run and rarely fall to the ground. These monkeys live in small groups of between two and six individuals. These groups consist of an adult pair and one infant and several juveniles and/or subadults. Groups are territorial, and occupy ranges that overlap with other groups only slightly. Panamanian night monkeys use vocal, olfactory and behavioral forms of communication. There are at least nine vocal calls, including various types of grunts, screams, squeals, moans, and trills. Males develop a scent gland near their tail at the age of about one year that is used for scent marking. They also use urine washing, in which urine is rubbed on the hands and feet. These animals also use certain behavioral displays, including arched back displays, stiff legged jumping, urination, defecation, and piloerection.
