The masked jumping monkey ( Callicebus personatus ) is a primate species from the subfamily of the jumper monkeys within the family of the sakia monkeys (Pitheciidae).
features
Masked Jumping Monkeys are one of the larger jumper monkeys, they reach a head body length of 31 to 42 centimeters, the tail is 42 to 56 centimeters, significantly longer than the body. The weight is 1.0 to 1.6 kilograms, with the males being slightly larger than the females. The fur is long and dense, the hind legs long, the head small and rounded. The name-giving feature is the black-colored head, on the cheeks there are long, beard-like, also black hair. The rest of the body is yellow-brown or orange in color - there are two color morphs here. The long tail is colored the same as the body, it cannot be used as a pronging tail.
distribution and habitat
Masked jumping monkeys live in southeastern Brazil on the Atlantic coast . Their distribution area includes the south of Espírito Santo , the east of Minas Gerais and the north of Rio de Janeiro . Their habitat are the coastal forests.
Way of life
Masked jumping monkeys, like all jumping monkeys, are diurnal and mostly stay in the trees, they very rarely come to the ground. In the branches they move on all fours, they often jump too. They live in family groups that include a male, a female and their offspring, a total of two to seven animals. The two partners are monogamous , they often stay together for life. Masked jumping monkeys are territorial, with duet songs they draw the attention of their fellow species to territory, but aggressive encounters can also occur.
The diet of these animals consists mainly of fruits, but they also eat leaves and other parts of plants as well as insects. The female gives birth to a single young. After the first few days of life, the father takes on the main responsibility for the boy, he carries it around and only makes it suckle for the mother.
Danger
The habitat of the masked jerkin is in one of the most densely populated regions of Brazil, and their range is accordingly reduced in size and fragmented. The main threat is the ongoing destruction of the habitat, hunting plays little or no role at all. The IUCN lists the species as "endangered" ( vulnerable ).
In Europe, the species is no longer maintained, former owners are Cologne, Hamburg and Rotterdam.
Systematics
The masked jumping monkey is one of around 30 species of the genus jumping monkey ( Callicebus ). Within this genus , it is the eponymous member of the personatus species group, which also includes the northern Bahia ape , the Coimbra ape , the southern Bahia ape and the black- fronted ape . Until recently, all of these species were combined into one species with the masked jumping monkey. The jumper monkeys of the personatus group are the largest representatives of their genus and are the only ones not found in the Amazon basin, but in southeastern Brazil.
