Diet

Fruit makes up 65–90 percent of the orangutan diet. Fruits with sugary or fatty pulp are favored. Ficus [fig tree] fruits are commonly eaten, because they are easy to harvest and digest. Lowland Dipterocarp [type of tropic] forests are preferred by orangutans because of their plentiful fruit. Bornean orangutans consume at least 317 different food items that include: young leaves, shoots, seeds, bark, insects, honey, and bird eggs.
