The three-striped night monkey (Aotus trivirgatus), also known as northern night monkey or northern owl monkey, is one of several species of owl monkeys currently recognised. It is found in Venezuela and north-central Brazil.

Until 1983, all the owl monkeys were regarded as subspecies of Aotus trivirgatus, and all were referred to as douroucoulis. The use of the name douroucouli exclusively for the three-striped night monkey is not universally accepted; some authors use it for the entire genus, or for the grey-necked group of species within it (to which A. trivirgatus belongs).

Like other owl monkeys, the three-striped night monkey lives in woodlands including rain forest. It is mainly black, with striking white markings on its face. Its body size is 27–48 cm, and its tail is about the same length again. Adults weigh up to 1 kg. It has very large eyes, and is most active on moonlit nights, feeding on fruit, nuts, leaves, insects and other small invertebrates, and birds' eggs.

The three-striped night monkey forms pair bonds which are broken only by the death of one partner. It lives in family groups, with the immature young staying with their parents until sexual maturity at the age of 3 or 4. Normally only one infant is born, after a gestation period of a little over 4 months.

Night monkey

Night monkeys, also known as owl monkeys or douroucoulis, are nocturnal New World monkeys of the genus Aotus, the only member of the family Aotidae. The genus comprises eleven species which are found across Panama and much of South America in primary and secondary forests, tropical rainforests and cloud forests up to 2,400 metres (7,900 ft). Night monkeys have large eyes which improve their vision at night, while their ears are mostly hidden, giving them their name Aotus, meaning "earless".

Gray-bellied night monkey

The gray-bellied night monkey, also called the grey-legged douroucouli or lemurine owl monkey, is a small New World monkey of the family Aotidae. Native to tropical and subtropical forests of South America, the gray-bellied night monkey faces a significant threat from hunting, harvesting for use in pharmaceutical research and habitat destruction.

Rio Abiseo National Park

The Rio Abiseo National Park is located in the San Martín department of Peru. UNESCO pronounced it as Natural and Cultural Heritage of Humanity in 1990. The park is home to many species of flora and fauna, as well as the location of over 30 pre-Columbian archaeological sites. Since 1986, the park has not been open to tourism due to the fragile nature of both the natural and archaeological environment.

White-eared titi

The white-eared titi, Plecturocebus donacophilus, also known as the Bolivian titi or Bolivian gray titi, is a species of titi, a type of New World monkey, from eastern Bolivia and an area of western Brazil. The species has a range that extends east from the Manique River in Beni Department, Bolivia to southern Rondônia in Brazil. The southern end of its range includes forests around the city of Santa Cruz de la Sierra.

Azaras night monkey

Azara's night monkey, also known as the southern night monkey, is a night monkey species from South America. It is found in Argentina, Bolivia, Brazil, Peru and Paraguay. The species is monogamous, with the males providing a large amount of parental care. It is named after Spanish naturalist Félix de Azara. Although primarily nocturnal, some populations of Azara's night monkey are unique among night monkeys in being active both day and night. The species is listed as Least Concern on the IUCN Red List.

Nancy Mas night monkey

Nancy Ma's night monkey is a night monkey species from South America. It is found in Brazil and Peru.

Peruvian night monkey

The Peruvian night monkey, also known as the Andean night monkey, is a nocturnal New World monkey endemic to northern Peru. Adults weigh around 1 kg (2.2 lb) and measure up to 50 cm (20 in) in length. Its colour is grey to light brown with characteristic black and white markings on the face. The chest, belly and upper arms are orange tinged, however, to a lesser extent then Aotus nigriceps.

Spixs night monkey

Spix's night monkey is a night monkey species from South America. It is found in Brazil, Colombia, Ecuador and Peru.

Black-headed night monkey

The black-headed night monkey is a night monkey species from South America. It is found in Bolivia, Brazil and Peru. The A. nigriceps in Peru were notably inhabiting areas that were degraded, and often these areas were disturbed either by human activities or natural occurrences in the ecosystem.

Hamlyns monkey

The Hamlyn's monkey, also known as the owl-faced monkey, is a species of Old World monkey that inhabits the bamboo and primary rainforests of the Congo. This species is exceedingly rare and known only from a few specimens; little is known about it. However these specimens tend to be widely dispersed throughout the eastern part of Congo, from the Epulu River to the Lukuga River and from the Congo River to the Kabale Forest, with one example in northwestern Rwanda. Geographically it corresponds quite closely to another species of monkey, L'Hoest's monkey C. lhoesti. It travels on the ground, and researchers think that it may be awake primarily by night.

The Jamaican monkey is an extinct species of New World monkey first uncovered at Long Mile Cave in Jamaica by Harold Anthony in 1920. Anthony is responsible for many species descriptions of Caribbean taxa during this period and his field notes record the discovery of the monkey material:

“January 17 – Spent all day digging in the long mile cave and secured some good bones. The most important find was the lower jaw and femur of a small monkey, found in the yellow limestone detritus. It was not associated with the human remains but not so far from them that the animal must not be strongly suspected as an introduced species. It was deeper than any of the human bones by at least 10” to 1’…”

Brumbacks night monkey

Brumback's night monkey is a species of night monkey found in Colombia. It has traditionally been considered a subspecies of gray-bellied night monkey, Aotus lemurinus. but it has recently been argued that it should be considered a separate species.

Panamanian night monkey

The Panamanian night monkey or Chocoan night monkey is a species of night monkey formerly considered a subspecies of the gray-bellied night monkey of the family Aotidae. Its range consists of Panama and the Chocó region of Colombia. There are also unconfirmed reports of its occurrence in Costa Rica, especially on the Caribbean coast of Costa Rica. The species definitely occurs in the Atlantic lowlands of Panama close to the Costa Rica border.

Gray-handed night monkey

The gray-handed night monkey is a species of night monkey formerly considered a subspecies of Gray-bellied night monkey of the family Aotidae. Its range consists of parts of Colombia and Venezuela. The exact classification of the gray-handed night monkey is uncertain. While some authors consider it a subspecies of the gray-bellied night monkey, A. lemurinus, other authors consider it a separate species, A. griseimembra.

Hernández-Camachos night monkey

Hernández-Camacho's night monkey is a species of night monkey of the family Aotidae. It was first described in 2007 by Thomas Defler and Marta Bueno. It has a gray neck and a white patch over each eye, separated by a black band. The fur on the chest, belly, lower arms and lower wrists is thick and white. It differs from other gray-necked night monkey species other than Brumback's night monkey in having 50 chromosomes.

Aotus dindensis is an extinct species of New World monkeys in the genus Aotus from the Middle Miocene. Its remains have been found at the Konzentrat-Lagerstätte of La Venta in the Honda Group of Colombia.
