Orangutan

Orangutans are large, long-armed apes native to Borneo and Sumatra, with reddish hair and no tails. They spend much of their lives in trees, moving carefully between branches. Fruit is a major food, supplemented by leaves, bark and other forest resources. Mothers care for dependent young over an extended period, teaching them where and how to feed. Adults build sleeping nests from branches and leaves. Many mature males develop broad cheek pads and use long calls to communicate through the forest.
