Habitat
They primarily inhabit tropical and subtropical evergreen forests in the hilly and mountainous regions of Northeast India, Bangladesh, and Myanmar. These gibbons prefer dense canopies at elevations up to 2,000 meters, where they can move freely among the trees.
Diet
Eastern hoolock gibbons mainly eat fruits such as figs and berries, supplemented by leaves, flowers, and occasionally insects. They forage in the upper canopy during the day, using their dexterous hands to pluck food items. Feeding behavior includes selective browsing to avoid toxic plants.
Behavior
They live in small family groups consisting of a mated pair and their offspring, exhibiting strong pair bonds and cooperative care of young. Eastern hoolock gibbons are diurnal and highly arboreal, spending most of their time swinging through trees and communicating with loud, melodious calls to defend territories. They are territorial, with groups maintaining defined home ranges through vocal displays and chases.
Conservation Status
The IUCN status of the Eastern hoolock gibbon is Endangered, with populations declining due to habitat loss from deforestation and hunting for the pet trade. Major threats include fragmentation of forest habitats and human encroachment.
