Orangutans build crude nests, and they are the only animals who build a roof when it rains. Orangutans live in the canopy of the rain forest. Adaptations Orangutans are much like humans, and they are very intelligent. They are tree dwelling animals. When they travel through trees, they don't move to the next branch until they have a firm grip on it.
Orangutans often drop seeds while they are traveling though trees.
That makes more food for them. There are a little more than five thousand orangutans left in the world. Reasons for Endangerment Orangutans are endangered because people are shooting them, and wrecking their habitat by cutting down trees. When people cut down the trees, orangutans can not find food. Because people have been shooting the animals and cutting down trees, orangutans may disappear forever.
