Habitat
Bornean orangutans primarily inhabit lowland rainforests, peat swamp forests, and sometimes mountainous areas up to 1,500 meters in elevation on the island of Borneo. They prefer dense, tropical forests with tall trees for nesting and foraging, avoiding open or degraded areas. Their range is limited to Indonesia and Malaysia, specifically within Borneo's diverse terrain.
Diet
Bornean orangutans mainly eat fruits such as figs and durians, supplemented with leaves, bark, shoots, and insects like termites. They occasionally consume bird eggs or small vertebrates, and their feeding behavior involves careful selection and processing of food using tools like sticks. They are primarily frugivorous and feed during the day, spending hours foraging in the treetops.
Behavior
Bornean orangutans are largely solitary, with adult males being territorial and females often living alone or with their offspring. They are diurnal and arboreal, spending most of their time in trees building nightly nests from branches and leaves. They exhibit intelligent behaviors such as using tools to extract insects or process food, and communicate through long calls that can travel long distances.
Conservation Status
The IUCN status of the Bornean orangutan is Critically Endangered, with populations declining due to habitat destruction from logging and palm oil plantations, as well as poaching and human-wildlife conflict.
