The dark gray jumper monkey ( Plecturocebus cinerascens , syn .: Callicebus cinerascens ) is a species of primate from the subfamily of jumper monkeys within the family of sakia monkeys (Pitheciidae).
features
Dark gray jumper monkeys, like all jumper monkeys, are relatively small primates with dense, fluffy fur . This is predominantly colored dark gray in this species, on the back it turns brown. The tail is bushy and longer than the body, it cannot be used as a pronging tail. The head is small and rounded. There are beard-like hairs on the cheeks and throat, which, unlike related species, are not contrasting, but are also colored gray.
distribution and habitat
Dark gray jumper monkeys occur exclusively in the Amazon basin in Brazil . Their range is limited to the north by the Rio Madeira , to the west by the Rio Aripuanã and to the east by the Rio Tapajós . Their habitat are deeper forests.
Way of life
The way of life of the dark gray jumper monkeys is hardly known, it should correspond to that of the other jumper monkeys. They are diurnal tree dwellers who either move on all fours or jump through the branches. They live in family groups made up of a longstanding monogamous couple and their offspring. They are territorial, with duet songs the couples point out other animals to their own territory.
Their diet consists primarily of fruits. To a lesser extent, they also consume leaves, seeds and insects. As with all jumping monkeys, the father is likely to participate intensively in the rearing of the young, he is the main carrier and only gives the child to the mother to suckle.
Danger
The distribution area of the dark gray jumper monkeys is sparsely populated and relatively undisturbed. According to the IUCN , these animals are therefore not endangered species.
The only holder of European zoo history was Frankfurt from the 1960s to the 1970s.
