The Panama night monkey ( Aotus zonalis ) is a species of primate from the group of night monkeys (Aotidae). It is often considered a subspecies of the Colombian night monkey .
features
Panama night monkeys, like all night monkeys, are relatively small primates with large eyes and a long tail. They reach a weight of around 0.9 kilograms, a sexual dimorphism in terms of size is very weak, if at all. Their fur is gray-brown on the upper side, the belly is orange-brown, the hands and feet are provided with black hair. The head is rounded, the large eyes are brown. They are surrounded by white fields, along the head are three dark stripes, one outside of each eye and one across the forehead to the nose. They differ from other, closely related species in their black paws and the number of chromosomes .
distribution and habitat
Panama owl monkeys are the most northwestern range of all owl monkeys, possibly including the far east of Costa Rica , Panama and western Colombia west of the Andes . The exact dimensions are unclear, however, since the Hernández Camacho night monkey , which was newly described in 2007, was found within the range of the Panama night monkey. The habitat of this species are forests up to 1000 meters above sea level, although they can also occur in secondary forests and plantations.
Way of life and exposure
Little is known about the way of life of these animals; it probably corresponds to that of the other night monkeys. As a result, they are nocturnal tree dwellers who sleep in tree hollows or in thickets of plants during the day. They move through the branches jumping or on all fours. Outer monkeys live in monogamous family groups of two to five animals and inhabit fixed territories that they defend from other species. Their main diet consists of fruits, but they also eat leaves and insects. Due to their nocturnal lifestyle, they avoid competition with diurnal, more dominant species.
In parts of their range, the Panama night monkeys suffer from deforestation, but overall little is known about the degree of endangerment. The IUCN lists the species under “ data deficient ”.
