The red-headed spring monkey ( Cheracebus regulus , Syn . : Callicebus regulus ) is a primate species from the subfamily of the spring monkeys within the family of the sakia monkeys (Pitheciidae). It was formerly considered a subspecies of the collared jumper .
features
Red-headed jumper monkeys, like all jumper monkeys, are relatively small primates. The fur is long and dense, it is dark gray on the back and on the limbs, the chest and the belly are black-brown. The tail is longer than the body and bushy, it is black in color and cannot be used as a prehensile tail. The feet are dark, the hands orange. The head is small and round, it is bright red on top. A white or yellow, collar-like pattern extends along the throat to the ears.
distribution and habitat
Red-headed jerkers live in the western Amazon basin in the Brazilian state of Amazonas . Its range is limited to the north by the Rio Solimões , to the west by the Rio Javari and to the east and south by the Rio Juruá .
Way of life
The way of life of the red-headed jumper monkeys is hardly known, it should correspond to that of the other jumper monkeys. Jumper monkeys are diurnal tree dwellers that either move on all fours or jump through the branches. They live in family groups made up of a monogamous couple - with the partner often staying together for life - 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 other parts of plants 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.
