The collared jumper monkey or widow monkey ( Cheracebus torquatus , Syn .: Callicebus torquatus ) is a species of primate from the subfamily of jumper monkeys within the family of sakia monkeys (Pitheciidae).
features
Collared jumper monkeys are among the larger representatives of jumper monkeys, they reach a head body length of up to 36 centimeters. The tail is significantly longer at 46 centimeters, it is bushy and, like all jumper monkeys, cannot be used as a prehensile tail. The weight is 1.1 to 1.5 kilograms, with the males being slightly heavier than the females. The fur is dense and long, it is predominantly dark red to black-brown in color, with the belly and the inside of the limbs being lighter. The eponymous white or yellowish fur pattern extends down the throat.
distribution and habitat
Collared jumping monkeys live in the northern Amazon basin in Brazil . Their range is limited in the north by the Rio Negro and in the south by the Japurá and the Solimões . Their habitat are tropical rainforests .
Way of life
These primates are diurnal tree dwellers that rarely come to the ground. They move in the branches on all fours as well as jumping. They live in groups of two to seven animals, which are composed of a male, a female and the common young. The male and female live monogamous , they usually stay together for life. Groups inhabit small territories, which they point out to other members of their own species with morning duets.
The food of the collar-jumper monkeys consists mainly of fruits, to a small extent they eat insects.
After a gestation period of around five to six months, the female gives birth to a single young. After its first days of life, the father takes care of it intensively. He carries it around and only gives it to the mother to suckle.
Danger
Although the Collared Jumper Monkey is hunted by indigenous peoples, overall it is not one of the endangered species according to the IUCN .
The species is no longer kept in Europe, the only former owner is Cologne.
Systematics
The collared jumper monkey is one of around 30 species from the subfamily of jumper monkeys (Callicebinae). He was the namesake of the torquatus species group within the genus Callicebus , which was also listed as a separate subgenus Torquatus . The animals of this group of species are relatively large, they have a dark, rather monochrome coat and, in contrast to the other jumper monkeys, hardly feed on leaves. In addition to the collared jumper monkey, this group also includes the Lucifer jumper monkey , the black jumper monkey , the blackhand jumper monkey , the Rio Purus jumper monkey and the redhead jumper monkey . All of these species were previously listed as subspecies of the Collared Jumping Monkey. In March 2016, the torquatus species group was transferred to an independent genus ( Cheracebus ).
