The white-fronted jumper monkey ( Plecturocebus ornatus , syn .: Callicebus ornatus ) 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-fronted jumper monkeys, like all jumper monkeys, are relatively small primates with fluffy fur . This is gray on the back and on the upper arms and legs, the belly and the forearms and legs are reddish and the paws are whitish. The rear legs are relatively long as an adaptation to jumping locomotion. The tail is long and bushy and does not serve as a prehensile tail. It is colored reddish brown at the base of the tail, the rear part is whitish. The head is small and round, the top is red-brown in color. The eponymous white horizontal stripe extends along the forehead, and the small ear tufts are also white. The hair on the cheeks and throat are reddish brown.
distribution and habitat
White-fronted jumper monkeys inhabit a small area in Colombia in the departments of Cundinamarca and Meta . They thus occupy a special position within their species group, the cupreus group , as their closest relatives all live in the Amazon basin more than 400 kilometers south. Their habitat is forests, mostly near rivers.
Way of life
The way of life of the white-fronted jumper monkeys is likely to resemble that of the other jumper monkeys. They are diurnal and mostly stay in the trees. The locomotion takes place either on all fours or with jumps. They live strictly monogamous in family groups of a male, a female and their offspring, the partners often stay together for life. Groups inhabit 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 and insects. 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
The distribution area of the white-fronted juggler monkey is relatively small, it covers around 20,000 km², but has been reduced and fragmented by human clearing and settlement activities. The IUCN lists the species as "endangered" ( vulnerable ).
