Saki monkey
Sakis' range includes northern and central South America, extending from the south of Colombia over Peru in northern Bolivia and into the central part of Brazil. Sakis are smaller monkeys with long, bushy tails. Their furry, rough skin is black, grey or reddish-brown colored depending upon the species. The faces of some species are naked, but their head is hooded with fur. Their bodies are adapted to life in the trees, wit strong hind legs allowing them to make far jumps. Sakis reach a length of 30 to 50 cm, with a tail just as long, and weigh up to 2 kg. Sakis are diurnal animals. They live in the trees of the rain forests and only occaisionally go onto the land. They mostly move on all four, sometimes running in an upright position on the hind legs over the branches, or by jumping long distances. For sleeping they roll themselves cat-like in the branches together. They are generally very shy, cautious animals. Sakis live in family federations, which consist of parents and their offspring, with mated pairs usually forming lifelong pair bonds. They are territorial animals, defending their territory in relation to other families. Sakis know a set of communication possibilities: while shrill cries or bird-like twitter serves as a connection among family members, a loud roar is to warn off other animals of the own territory. Sakis are omnivores. They eat fruits, leaves and flowers, and insects and small vertebrates (such as rodents and bats). The mating is non-seasonal, and can happen any time during the year. After approximately 150 to 180 day gestation, females bear single young. The young are weaned after 4 months, and are fully mature in 3 years. Their life expectancy is up to 14 years. Classification
