Orangutans live in the humid, tropical rainforests of Borneo and Sumatra, where tall trees up to 150 feet high provide habitat in the lower canopy. They eat a variety of fruits, insects, eggs, and small animals found in the trees using their hands and feet. Orangutans are solitary and mostly arboreal, sleeping high in the trees at night after making nests and moving quietly during the day to find food. Females give birth every 4-5 years and teach their young how to survive on their own.
