Peruvian night monkey

The Peruvian night monkey, Aotus miconax, also known as the Andean night monkey, is a nocturnal monkey found only in northern Peru. Adults weigh about a kilogram and measure up to half a metre, with grey to light brown fur, orange-tinged chest and upper arms, and black and white markings on the face. It lives in cloud forest at roughly 900 to 2,800 metres above sea level in the departments of Amazonas, Huánuco and San Martín, in small monogamous family groups of two to six animals, and eats fruit, leaf buds and insects. It is one of the least studied of all primates and possibly one of the rarest Neotropical monkeys, known mostly from museum specimens and sightings. Its forests are being cleared for farmland and pasture, and some animals are taken for the pet trade or by trophy hunters, so it is listed as Endangered by the IUCN and under Peruvian law.
