Common names: Borneon orangutan; Orangoutan de Borneo (Fr)
Scientific names: Pongo Pygmaeus
Location: Borneo (Malaysia and Indonesia)
Population: 45,000 - 69,000 wild individuals

Adult orangutans are generally solitary, although temporary aggregations are occasionally formed.
Although arboreal, Bornean orangutans (especially adult males) more often descend to the ground than Sumatran orangutans.
The age of first reproduction for females is around 10-15 years of age, but there may be differences between the subspecies. The inter-birth interval can be as low as 5 years in high-quality habitats.
About 60% of the orangutan's diet comes from fruit, with the rest comprising young leaves and shoots, insects, soil, tree bark, woody lianas, and occasionally eggs and small vertebrates.
