Share this image — Hide sharing options. The grey-legged night monkey belongs to the nocturnal primate genus Aotus , which is also one of the most widespread primate genera in the neotropics. This species is a relatively small monkey, and there are no differences in appearance between males and females. This monkey has a slightly astonished look due to its large eyes, but unlike many nocturnal species, the eyes do not shine in torch light. The coat is thick and two-tone; the tips of the fur are greyish-brown with much lighter bases on the back 3 , and pale yellow or orange on the underside 4.

The gray-bellied night monkey Aotus lemurinus , also called the grey-legged douroucouli [3] or lemurine owl monkey , is a small New World monkey of the family Aotidae.

Native to tropical and subtropical forests of South America , [4] the gray-bellied night monkey faces a significant threat from hunting, harvesting for use in pharmaceutical research and habitat destruction. There have been up to four subspecies of the gray-bellied night monkey.

Additionally, Hershkovitz's night monkey Aotus hershkovitzi is now considered to be a junior synonym for A. Like other members of their genus, this species is nocturnal ; its small, round head is striped with black and is dominated by two large, brown eyes. The overall effect is not unlike an owl ; the monkey's eyes shine a reddish orange by reflected light. Its white eyebrows are bushy, with a patch of darker fur between them.

Its grey fur is described as dense and woolly, with the animal's underside being yellow to orange in colour. Its brownish black to orange tail is not prehensile and invariably tipped with black. The gray-bellied night monkey has slender limbs with long, delicate fingers; its fingertip pads are wide. Adults may attain a weight of 1. Found in both dry and moist areas, the gray-bellied night monkey occupies all levels of the forest canopy; however, it is seldom found on the ground.

It prefers dense vegetation with tangles of vines where the trees are evenly dispersed. Its range is from Colombia and north-eastern Argentina to Venezuela , Ecuador and Panama ; it is also found in the tropical Andes. By day the monkey slumbers in the cavities of trees or in dense thickets; by night, it searches the canopy for a variety of food items. Primarily a frugivore fruit -eating , this monkey also eats vegetation, insects , nectar , and even other small mammals and birds when fruit is scarce.

Most active during twilight hours and periods of bright moonlight, the gray-bellied night monkey troop consists of a mated pair and their offspring, up to five individuals in total. This species is noted for the monogamous pair-bond it forms; parental duties are shared between the lead pair and the juveniles.

However, it is the male who assumes the bulk of care giving and rearing responsibilities; the female serves only to nurse the infants.

Remarkably, even if the male dies the female will refuse to take over from him. Characteristically vociferous , the monkey produces a range of calls: from soft clicks and low-pitched guttural rumblings to owl-like hoots and high-pitched shrieks when threatened. When not feeding, the monkey is typically inactive. Like other members of its genus, the gray-bellied night monkey claims a relatively small territory of about 0.

Scent is central to this monkey's intraspecies communication ; territories are marked with brown, oily secretions from the base of the tail. Birthing peaks at the end of the dry season and in the midst of the wet season. Gestation averages days, usually resulting in a single infant; twins are a rarity.

There is only one litter per year. Sexual maturity is reached at 2. From Wikipedia, the free encyclopedia. Gray-bellied night monkey [1] Conservation status. Geoffroy , Wilson, D. Baltimore: Johns Hopkins University Press.
