White-faced Saki (Pithecia pithecia)
Sakis are small-sized monkeys with long, bushy tails. Their furry, rough skin is black, grey or reddish-brown in color depending upon the species. The faces of some species are naked, but their head is hooded with fur. Their bodies are adapted to life in the trees, with strong hind legs allowing them to make far jumps. Sakis reach a length of 30 to 50 cm, with a tail just as long, and weigh up to 2 kg.
Habitat and Habit
Sakis are diurnal animals. They live in the trees of the rain forests and only occasionally go onto the land. They mostly move on all fours, sometimes running in an upright position on the hind legs over the branches, and sometimes jumping long distances. For sleeping they roll themselves cat-like in the branches. They are generally very shy, cautious animals.
Mating is non-seasonal, and can happen any time during the year. After approximately 150 to 180 day gestation, females bear single young. The young are weaned after 4 months, and are fully mature in 3 years. Their life expectancy is up to 30 years.
