The White browed Gibbon is a primate from the gibbon family, Hylobatidae.

The species is found in Assam, Mizoram & Meghalaya in India, Bangladesh and in Myanmar west of the Chindwin River.

The White browed Gibbon is a small arboreal ape weighing a little over 13 lb. It exhibits sexual dichromatism: the adult male is always black, except for its prominent white eyebrows, while the adult females fur is gold or buff or brownish buff.

The White browed Gibbon is found in good quality semi-deciduous evergreen forest up to 4500 feet. Fruit comprises the majority of its diet, which also includes leaves, flowers, buds and a small amount of insects and spiders.

Like other gibbons, the White browed Gibbon pairs produce a loud, elaborate song, usually sung as a duet from the forest canopy, in which younger individuals of the family group may join in.

The song includes an introductory sequence, an organising sequence, and a great call sequence, with the male also contributing to the latter.

Mootnick and Groves stated that hoolock gibbons do not belong in the genus Bunopithecus, and placed them in a new genus, Hoolock.

This genus was argued to contain two and later three distinct species which were previously thought to be subspecies: Hoolock hoolock, Hoolock leuconedys and Hoolock tianxing.

It was later found that there is a larger evolutionary distance between these three species and the white-handed gibbons than there is between bonobos and chimpanzees.

In India and Bangladesh the Tooboung Gibbon is found where there is contiguous canopy, broad-leaved, wet evergreen and semi-evergreen forests dipterocarpus forest often mountainous.

The species is an important seed disperser; its diet includes mostly ripe fruits, with some flowers, leaves and shoots.

There are numerous threats to White browed Gibbons in the wild, and are now entirely dependent on human action for their survival.

Threats include habitat encroachment by humans, forest clearance for tea cultivation, the practice of jhuming (slash-and-burn cultivation), hunting for food, “medicine”, capture for trade, and forest degradation.

Over the last 30 to 40 years, White browed Gibbon numbers are estimated to have dropped from more than 100,000 to less than 5,000 individuals.

Since the 1980s, western hoolock gibbon numbers are estimated to have dropped from more than 100,000 (Assam alone was estimated to have around 80,000 in the early 1970s) to less than 5,000 individuals (a decline of more than 90%).

In 2009 it was considered to be one of the 25 most endangered primates, though it has been dropped from the later editions of the list, and is rated as endangered by the IUCN.

There are multiple conservation agencies that work to protect the Tooboung Gibbon’s habitat. A few organizations that help to fund the protection of their habitats are World Land Trust and Gibbon Conservation Alliance.
