The brown jumper monkey ( Plecturocebus brunneus , syn .: Callicebus brunneus ) is a primate species from the subfamily of jumper monkeys within the family of sakia monkeys (Pitheciidae).
features
Brown jumper monkeys, like all jumper monkeys, are relatively small primates with long, thick fur . This is colored gray-brown on the back, the top of the head and the limbs are colored black-brown, the belly is red-brown. The tail is bushy and longer than the body. Except for the dark tail root, it is white or light gray and, like all jumper monkeys, cannot be used as a prehensile tail. The small, rounded head has long, beard-like hair on the cheeks and throat, which are reddish-brown in color.
distribution and habitat
Brown jumper monkeys are found in the west of Brazil. Its distribution area largely coincides with the territory of the state of Rondônia and is enclosed in the northwest by the Rio Madeira , in the northeast and east by the Rio Jiparaná and in the west and southwest by Río Mamoré and Rio Guaporé . The brownish jugular monkeys found in eastern Peru, which were originally also classified as Callicebus brunneus , are now considered a separate species ( Callicebus urubambensis ). The habitat of the brown jumper monkeys are forests, whereby they can occur in different forest types.
Way of life
Brown jumper monkeys are diurnal and mostly stay in the trees, especially in the lower shrub layer. There they either move on all fours or jump. They live in family groups that consist of a full-grown couple and their offspring. They are monogamous , the partners often stay together for life. They inhabit fixed territories, these are marked with morning duets, but in an emergency they are also aggressively defended against conspecifics.
Their diet consists mainly of fruits, but they also eat leaves and insects.
After around five months of reproduction, the female gives birth to a single young. After a few days, the father takes on the main responsibility for the boy, he carries it around and only makes it suckle for the mother.
Danger
In Bolivia, brown monkeys are hunted for their meat, in Brazil habitat destruction is the main threat. However, the species is found in a number of protected areas and is listed by the IUCN as least concern .
