India's only ape species lives in the forests of Northeast. Join our wildlife expedition to spot these elusive primates in their natural habitat.
The Hoolock gibbon is a marvel of evolution—India's only ape species and one of the world's most acrobatic primates. With their long arms and graceful movements, they swing through the dense forests of the Northeast like aerial dancers. Spotting a Hoolock gibbon in the wild is a privilege reserved for patient observers and those willing to venture deep into remote forests.
The Endangered Acrobat
Hoolock gibbons are small apes, weighing only 6-9 kilograms, yet they command respect in their forest domain. They live exclusively in the forests of Northeast India, Southeast Asia, and parts of southern China. There are three species: the Western Hoolock, the Eastern Hoolock, and the newly recognized Skywalker hoolock (named after Anakin Skywalker from Star Wars). Today, all three species are threatened by habitat loss, with populations declining rapidly.
Their Haunting Call
One of the most magical aspects of encountering Hoolock gibbons is hearing their morning call. Beginning at dawn, these primates produce a series of loud, melodious hoots that echo through the forest—a haunting symphony that can be heard from kilometers away. The calls serve multiple purposes: marking territory, maintaining family bonds, and locating mates. There is nothing quite like hearing the ethereal sound of gibbons calling across a misty forest valley.
Where to Find Them
The best locations to spot Hoolock gibbons are in protected forests and wildlife sanctuaries across Assam, Arunachal Pradesh, and Meghalaya. Hollongapar Gibbon Sanctuary in Assam is home to the Western Hoolock gibbon and offers the most reliable viewing opportunities. Dehing Patkai Wildlife Sanctuary and several national parks also host populations of these remarkable creatures.
The Perfect Family Unit
Hoolock gibbons are monogamous creatures that live in stable family groups of 2-4 members. They form strong pair bonds and are devoted parents, with both males and females participating in caring for their young. Watching a gibbon family move through the canopy—parents leading the way while juveniles follow with varying degrees of confidence—is a humbling reminder of the universal bonds of family that transcend species.
Conservation Efforts
Several organizations are working tirelessly to protect Hoolock gibbons through habitat conservation, anti-poaching measures, and community engagement. Local tribes and forest communities play a crucial role in this conservation work. Many sanctuaries employ local guides and forest watchers, creating both livelihood opportunities and stronger conservation outcomes.
Tips for Spotting Gibbons
Early morning is your best bet—head into the forest at dawn and listen for their calls. Move slowly and quietly, and hire experienced local guides who know the forest intimately. Patience is essential; it may take hours of quiet waiting. Binoculars are invaluable for observing them high in the canopy without disturbing the animals. Remember that viewing gibbons requires respect for their space and the pristine ecosystems they inhabit.
