The Panamanian night monkey is arboreal and nocturnal.[1] It and the other members of the genus Aotus are the only nocturnal monkeys.[9] It is found in several types of forest, including secondary forest and coffee plantations.[3] It lives in small groups of between two and six monkeys, consisting of an adult pair and one infant and several juveniles and/or subadults.[6] Groups are territorial, and groups occupy ranges that overlap only slightly.[6]
