orangutan borneo

The Bornean Orangutan is more solitary than the Sumatran Orangutan. Two or three orangutans that have overlapping territories may interact for small periods of time. Males and females generally come together only to mate. Sub-adult males will try to mate with any female, though they probably mostly fail to impregnate them since mature females are easily capable of fending them off. Mature females prefer to mate with mature males.

Newborn orangutans nurse every three to four hours, and begin to take soft food from their mothers' lips by four months. During the first year of its life, the baby clings to its mother's abdomen by entwining its fingers in and gripping her fur. Babies stay with their mothers until they are about eight or nine years old and have a long childhood compared to other apes
