The Orangutans (Pongo pygmaeus) are great apes native to Indonesia and Malaysia. They are found in the rainforests of Borneo and Sumatra.
Orangutans are the most arboreal of the great apes and spend most of their time in trees. Their hair is reddish-brown, instead of the brown or black hair typical of chimpanzees and gorillas. Flanged (with distinctive cheek flaps) adult males make long calls that attract females and intimidate rivals. Orangutans are the most solitary of the great apes, with social bonds occurring primarily between mothers and their dependent offspring, who remain together for the first two years. Fruit is the most important component of an orangutan's diet; however, the apes will also eat vegetation, bark, honey, insects, and bird eggs. They can live for over 30 years both in the wild and in captivity.
