Sumatran Orang Utan (Pongo Pygmaeus) — Taman Nasional Gunung Leuser, Bahorok
Orang-utans have brown and rust-colored shaggy fur. They weigh an average of 50 kg (110 lb) and can weigh over 90 kg (200 lb). The orang-utan lives in tropical, swamp and mountain forests, where it eats mostly fruit, leaves and insects. The orang-utan is arboreal and diurnal . It exhibits a sophisticated use of tools for gathering food. Twigs and branches are utilized to construct a large nest-platform in a tree to sleep in at night.
Adult orang-utans are generally solitary, except when a male and a female are together for mating. The home range of an adult male usually overlaps the ranges of several adult females. Orang-utans are not territorial . Most animals in a given area appear to maintain a loose relationship, although adult males are hostile to one another. A single young is usually born about every six years.
The orang-utan was once found throughout Indo-China, Malaysia and north to China . In historical times it has only been known from Sumatra and Borneo . About 100 years ago it was present in most of the rainforest areas on these islands; however, it was never found in large numbers. It has declined drastically since then. The major causes of the orang-utan’s decline have been 1.) in the past, capture for the pet and zoo trade, especially the capture of young, which usually involved killing the mother; and 2.) habitat loss, especially through permanent conversion to oil-palm plantations and for logging.
