The northern Bahia jumper monkey ( Callicebus barbarabrownae ) is a primate species from the subfamily of jumper monkeys within the family of sakia monkeys (Pitheciidae). Until the end of the 1990s, it was considered a subspecies of the masked jumper .
features
Northern Bahia jumper monkeys, like all jumper monkeys, are relatively small primates with a long, bushy tail and thick, fluffy fur . This is colored dirty white or light gray on the back, on the flanks and on the outside of the limbs, the belly and the inside of the limbs are yellow-gray. The hands and feet are black, the long tail orange. As with all jumping monkeys, it cannot be used as a prehensile tail. The head is small and rounded, there is a black horizontal stripe on the forehead, and the tufts of ears are also black.
distribution and habitat
Northern Bahia apes live in southeastern Brazil . Their distribution area includes the northeast of Bahia and the west of the Sergipes , it reached in the north to the Rio São Francisco . Their habitat are the small forest areas that are scattered in the middle of the caatinga .
Way of life
Little is known about the way of life of the northern Bahia ape, presumably it largely corresponds to that of the other apes. Jumper monkeys are tree-dwellers and diurnal, they move four-legged or jump. Males and females live monogamous and often stay together for life. The family groups move into a fixed territory, which they defend aggressively against conspecifics if necessary. Their diet consists mainly of fruits, as well as leaves and possibly insects. The fathers participate intensively in raising the young, they carry the young around and leave it to the mother only to suckle.
Danger
The habitat of the northern Bahia ape has been massively affected by deforestation, and many areas have been converted into agricultural areas or settlement areas. In addition, there are reenactments by stray or feral pets and the hunt for pets. The total population comprises fewer than 250 adult animals that are spread across several populations - none of which comprises more than 50 animals. There are no protected areas in their habitat. The IUCN lists the species as critically endangered .
