Habitat
This gibbon primarily inhabits tropical rainforests in northern Borneo, favoring hilly and mountainous regions with dense canopies. They prefer primary and secondary forests at elevations up to 1,500 meters, where they can move easily through the trees. Their range is restricted to specific areas in Sabah, Sarawak, and Brunei.
Diet
Bornean white-bearded gibbons mainly consume ripe fruits like figs and berries, along with leaves, flowers, and occasionally insects. They forage in the upper canopy during the day, using their dexterous hands to pluck food, and may travel several kilometers to find seasonal resources. Feeding behavior is opportunistic, adapting to the availability of fruits in their territory.
Behavior
These gibbons live in small, monogamous family groups of 2-6 individuals, consisting of an adult pair and their offspring. They are diurnal and highly arboreal, spending most of their time swinging through trees and defending territories with loud, duet songs in the early morning. They exhibit strong pair bonds and playful interactions among juveniles, while being wary of intruders.
Conservation Status
The IUCN classifies the Bornean white-bearded gibbon as Endangered, with populations declining due to habitat loss from logging and palm oil plantations. Major threats include forest fragmentation and hunting for the pet trade.
