Ecology and behaviour

Most of the day is spent feeding, resting, and travelling. They start the day feeding for two to three hours in the morning. They rest during midday, then travel in the late afternoon. When evening arrives, they prepare their nests for the night. Potential predators of orangutans include tigers, clouded leopards and wild dogs.: 91 The most common orangutan parasites are nematodes of the genus Strongyloides and the ciliate Balantidium coli. Among Strongyloides, the species S. fuelleborni and S. stercoralis are reported in young individuals. Orangutans also use the plant species Dracaena cantleyi as an anti-inflammatory balm. Captive animals may suffer an upper respiratory tract disease.
