The white-tailed jumper monkey ( Plecturocebus discolor , syn .: Callicebus discolor , C. subrufus ) is a primate species from the subfamily of jumper monkeys within the family of sakia monkeys (Pitheciidae). It is closely related to the red jumper monkey and was previously considered its subspecies.
features
White-tailed jumper monkeys, like all jumper monkeys, are relatively small primates with dense, long fur and slightly elongated hind legs. Their fur is colored gray-brown on the back and on the upper arms and legs, the belly, the forearms and legs and the paws, which are reddish-brown, are strongly contrasting. The tail is long and bushy, it is colored gray-brown in the front part, the rear third is white. As with all jumping monkeys, it cannot be used as a prehensile tail. The head is small and rounded, there is a white horizontal stripe on the forehead and a black above it. The hair on the cheeks and throat are red.
distribution and habitat
White-tailed jumper monkeys live in northern Peru , eastern Ecuador, and a small area in the extreme south of Colombia . Their distribution area is limited in the south by the Marañón and in the east by the Río Ucayali . Their habitat are forests, they often occur in river forests.
Way of life
Little is known about the way of life; it probably resembles that of the red jumper. They are diurnal and are mainly in the trees. There they move on all fours and sometimes jump. They live in family groups in which the partners often spend their entire lives together. These groups live in fixed territories, which they indicate to other animals by singing duets in the morning. Their diet consists mainly of fruits and, to a lesser extent, leaves and other parts of plants such as seeds and flowers. The father takes an active part in raising the young, he carries the young around and only brings it to the mother to suckle.
Danger
Although they are endangered in some places due to the destruction of their habitat, overall white-tailed juggler monkeys are not endangered species according to the IUCN .
