The only great apes that live outside of Africa are orangutans, of which there are two species. The Sumatran orangutan is more endangered than the Bornean orangutan. The two differ in appearance and behavior, with Sumatran orangutans being slightly smaller and usually having hair that is lighter colored and orange-red, as well as a longer beard. Sumatran orangutans lead very solitary lives, during the day moving slowly in search of food through the trees. Up to 60% of an orangutan’s time is spent foraging and eating, and, although they can occupy large home ranges, half a mile a day is the most they usually travel. At night, they build a nest for sleeping up high in the canopy out of folded branches. They are not very territorial, sharing their home ranges with others, sometimes feeding alongside other orangutans around especially abundant fruit trees.
