What Eats It?
The Sumatran orangutan was traditionally preyed on by tigers and snow leopards.
Orangutans are mostly solitary except for mating pairs and females with offspring. Encounters between mature males can result either in aggression or avoidance. Females are more tolerant and may be seen with other adult females or adolescents other than their own. Wild orangutans are almost arboreal. Adults and juveniles will play in social settings or alone.
Orangutans mature slowly. Females are mature at eight to ten years of age but generally do not bear their first offspring until they are 14 to 16 years old. Males are sexually mature at 13 to 15 years of age. Females are in estrus only a few days a year during which mating can occur. After a gestation of 260-270 days females give birth to a single offspring weighing three to four-and-a-half pounds (1.3-2 kg). Infants are carried by their mothers for two to three years and nursed for up to six or seven years. A female will bear young every eight or nine years and will raise only three or four young during her lifetime. Both female and male offspring go off on their own once they reach maturity. Orangutans may live up to 35-45 years in the wild and up to 50 years in captivity.
