The Beni spring monkey ( Plecturocebus olallae , syn .: Callicebus olallae ) is a primate species from the subfamily of the spring monkeys within the family of the sakia monkeys (Pitheciidae).
features
Beni jumper monkeys, like all jumper monkeys, are relatively small primates with fluffy fur . This is colored orange-brown on the back and on the outside of the limbs, the belly and the inside are lighter. The tail is dark gray and contrasts with the rest of the body, it is long and bushy, but cannot be used as a prehensile tail. The head is small and rounded, the gray face is surrounded by a wreath of black hair. The ear tufts are colored white. The rear legs are elongated to adapt to jumping locomotion.
distribution and habitat
Beni jumping monkeys only inhabit an area of around 400 km² in the southwest of the Bolivian department of Beni , where they live along the Yacuma and Manique rivers. Their habitat are gallery forests , they live below 400 meters above sea level.
Way of life
Little is known about the way of life of the Beni jumping monkeys. Like all jumping monkeys, they are probably diurnal tree-dwellers who move on all fours or jump through the branches. Jumper monkeys live in strictly monogamous family groups. These groups live in a fixed territory to which conspecifics are made aware with morning duets. The food is likely to consist of fruits and, to a lesser extent, leaves and other plant material and possibly insects.
Danger
Deforestation and possibly also hunting are the main threats to the Beni ape monkeys. Due to these factors and the small distribution area, the IUCN lists the species as endangered .
