The Hoffmann's spring monkey ( Plecturocebus hoffmannsi , Syn .: Callicebus hoffmannsi ) is a primate species from the subfamily of the jumping monkeys within the family of the sakia monkeys (Pitheciidae).
features
Hoffmann's jumper monkeys, like all jumper monkeys, are relatively small primates with fluffy fur , a small, rounded head and a long, bushy tail. The fur is colored gray on the back, on the flanks, on the top of the head and on the outside of the limbs, whereby the color on the top of the back can turn olive green. The abdomen and insides of the limbs are strongly contrasting yellowish or white. The tail, which is longer than the body, is black and, unlike related species, does not have a white tip. A black horizontal stripe can extend along the forehead, and there are long, yellowish-white, beard-like hairs on the cheeks and throat.
distribution and habitat
The distribution area of the Hoffmann's jumper is in the eastern Amazon basin in Brazil . They live in the region where the Rio Tapajós flows into the Amazon , south of the Amazon and west of the Tapajós. Their habitat are deep forests.
Way of life
Little is known about the way of life of the Hoffmann's jumper monkey, presumably it matches that of the other jumper monkeys. They are diurnal tree dwellers who move on all fours and occasionally jump. Jumper monkeys live in monogamous family groups in which the partners often stay together for life. These groups live in a fixed territory, which they mark with morning duets. Their diet consists mainly of fruits, to a lesser extent they eat leaves and other parts of plants and possibly insects. The fathers take an intensive part in raising the young, they carry the young and only make the mother suckle it.
Danger
Since Hoffmann's jumper monkeys live in a large, relatively untouched range, they are not endangered according to the IUCN .
The species is no longer kept in Europe, the former owner is Cologne in the 1960s.
