The White-headed Saki or Blasskopfsaki ( Pithecia pithecia ) is a species of primate from the New World monkey group .
description
White-headed sakis reach a head-trunk length of 30 to 48 centimeters, the bushy tail is about the same length as the body. The weight is around 1.5 to 1.8 kilograms, with the males being slightly heavier than the females. The hind legs are significantly longer than the front legs, the tail cannot be used as a prehensile tail. The fur is long and shaggy, the two sexes are clearly colored differently, especially in the facial area. The males are predominantly black, the face and throat are whitish in stark contrast. With their black-gray or brown-gray fur, the females are more similar to the other Sakis, with two white stripes extending from the corners of the eyes to the corners of their mouths. The nose is wide in both sexes and the nostrils are wide apart.
distribution and habitat
Bald sakis inhabit northeastern South America . Its distribution area includes Guyana , Suriname and French Guiana , the area east of the Guri reservoir in Venezuela, the Brazilian state of Amapá and the part of Pará north of the Amazon . Their habitat are forests, although they can occur in deep rain forests as well as in mountain forests.
Way of life
Bald sakis are diurnal tree dwellers that rarely come to the ground. They are often found in the middle or lower crown layer. They often move on all fours or climb vertically, but thanks to their strong hind legs they can also make long jumps. These animals live in small groups, possibly monogamous family groups. Their home ranges are very small with 4 to 10 hectares.
The diet of these animals consists mainly of seeds and fruits, to a small extent they eat other parts of plants and insects.
Reproduction
After a gestation period of around 163 to 176 days, the female usually gives birth to a single young. Mainly the mother takes care of the young, which is weaned after several months. In human care, the animals can reach an age of 35 years.
Danger
In the wild, the stocks of white-headed sakis are currently not threatened. The IUCN lists them as “not at risk” ( least concern ).
In Germany the species is kept in 17 facilities.
