Noisy Night Monkey

Description

Spix's night monkey (Aotus vociferans), also known as the Colombian gray night monkey, noisy night monkey and Spix's owl monkey, is a night monkey species from South America. It is found in Brazil, Colombia, Ecuador and Peru. The Spix's night monkey is a small bodied monkey species usually having a mass of around one kilogram. It belongs to the only nocturnal genus of New World primates, Aotus. This type of monkey can leap farther than most due to it having longer arms than legs. The monkey averages 0.5 meters in height. The night monkey is considered to be a new world monkey. The social behavior of the Aotus vociferans is group based. These groups usually consist of breeding pairs and their offspring. This species has a monogamous mating system. After the offspring are born, the father becomes the main caretaker, only giving up the offspring for them to suckle. The offspring will usually stay with their birth group until they reach two and a half to three and a half years old. An exception to this if the male breeding partner is no longer present for any reason (usually only caused by death), then the offspring may stay with its birth group for only twelve weeks to the normal departure age. Social grooming in this species of monkey is uncommon. The Aotus vociferans reproduce usually by giving birth to one offspring. Although, like with humans, there are cases of twins. The female breeding partner carries the offspring in interbirth for around one year.
