One of Asia's most famous species ... and one of the most endangered, the Orang Utan endears itself easily to us humans. Threatened by habitat loss and poaching this species is the most peaceful of the Great Apes. 

	Juveniles spend their time just hanging around.

Orang Utans feed mainly on forest fruits and young leaves. Adult males can reach a height of 1.4 metres, and the outstretched arms can measure up to 2.4 metres. Often solitary, this is the only primate which builds nests of small branches and twigs. Census studies of the Orang Utan often rely on counting these nests to gain a rough estimate of the population.

The Orang Utan is found only on the islands of Borneo and Sumatra, where there are estimated populations of around 15,000 and 9,000 respectively.
