The Andean night monkey is a nocturnal primate of cloud forests in northeastern Peru. Large brown eyes and three black facial stripes are features described for the genus Aotus. A study of one group in Peru found it using tree holes and vine tangles as sleeping sites.
The Aotus genus account describes gray-brown to brown fur, pale markings above and below the eyes, three black stripes across the face, and large brown eyes.
In one study of a group in a small cloud-forest patch in northeastern Peru, the monkeys used tree holes and vine tangles as sleeping sites and changed sites every three to five days.
