Brown-mantled tamarin

Braunrückentamarin ( Saguinus fuscicollis )

The Braunrückentamarin ( Saguinus fuscicollis ) is a primate of the family of marmosets ( Callitrichidae ). He lives in several subspecies in northern South America.

Features

Saddleback tamarins are like all marmosets relatively small primates, they reach a weight of around 320-550 grams. The shoulders and front legs are black or dark brown, the posterior part of the back and hind legs brown, the body can go on the rear end to make it reddish. The head is black, the large ears are hairless, the muzzle is white. As with all marmosets are located on the fingers and toes (except the big toe ) claws instead of nails.

Distribution and habitat

Saddleback tamarins are native to many parts of the western Amazon basin, their range includes southern Colombia, eastern Ecuador, eastern Peru, northern Bolivia and western Brazil and medium. Your habitat are rainforests, where they prefer dense undergrowth areas lined as forest edges and secondary forests. They occur in up to 1200 meters above sea level.

Lifestyle and diet

These primates, like all tamarins diurnal and arboreal. In branches they move away on all fours or jumping, thanks to their claws, they can also be good at climbing on vertical stems. Keep this almost always in the lower tree layers (below 10 meters) on.

Saddleback tamarins live in groups of 3 to 8 animals. Groups are usually made ​​up of several males, one female and the corresponding young animals. They often socialize with other Tamarinarten, such as the Emperor Tamarin. This Socialization presumably serve to be able to detect predators more quickly.

They are omnivorous, which mainly take insects, fruits and nectar to him.

Reproduction

The female mates with all the males of the group ( polyandry ). After a 140 - to 150 - day gestation, mostly twins are born. The young are very large, they have at birth already about 25 % of the mother's weight. All group members, especially the males, are involved in the breeding season. You wear them and give them the only mother to suckle. Sexual maturity occurs at the end of the second year of life.

Endangering

Saddleback tamarins are common and widespread, there are no major threats known. The IUCN lists the species as " not at risk " ( least concern ).

System

There are a total of 11 recognized subspecies, in addition to the nominate Saguinus fuscicollis fuscicollis still p f avilapiresi, p cruzlimai f, p f fuscus, S. illigeri f, p f leucogenys, p f lagonotus, p f mura, S. nigrifrons f, p f and p f Primitivus weddelli. Two other former subspecies are now considered separate species, the Weißmanteltamarin ( Saguinus melanoleucus ) and the Goldmanteltamarin ( Saguinus tripartitus ). However, this classification is not without controversy, perhaps these two species are more closely related with several subspecies than the subspecies together.
