Eastern Hoolock Gibbon Hoolock leuconedys

Eastern Hoolock Gibbon Hoolock leuconedys

Vulnerable

Extant (resident): Myanmar

Presence Uncertain: India

The Hoolock Gibbons are three species located in South Central Asia. They are the second largest of the gibbons after the Siamang. They have rings around their eyes and mouths giving them a mask-like appearance. Like other gibbon species they call to each other in regionalised accents, have long swinging arms and superior acrobatic skills.

The Eastern Hoolock Gibbon is a forest-dweller that inhabits primary evergreen, scrub and semi-deciduous hill forest, as well as mountainous broadleaf and pine-dominated forest. They range up to 2,700 m in elevation, (Kumar et al. 2013, Zhang et al. 2014) in mixed pine/broadleaf forest in northeastern Myanmar (Geissmann et al. 2013, Ujhelyi et al. 2000).

These gibbons are listed as Vulnerable because it is suspected that the population will decline by more than 30% over the next three generations (approximately 45 years), based on continued habitat loss and hunting throughout its range (Fan et al. 2011a, 2011b; Kumar et al. 2013).

IUCN Red LIst

The Eastern Hoolock Gibbon is a frugivorous species, with ripe fruits composing a majority of its diet. Individuals also eat a large proportion of figs and some amount of leaves, shoots, and petioles.

These gibbons ranges up to 2,700 m in elevation, (Kumar et al. 2013, Zhang et al. 2014) in mixed pine/broadleaf forest in northeastern Myanmar (Geissmann et al. 2013, Ujhelyi et al. 2000). Eastern Hoolocks Gibbons are threatened by habitat loss and hunting, both for meat as well as for use in traditional “medicine” (Fan et al. 2011a, Geissmann et al. 2013). In Myanmar, commercial logging may eliminate most forest habitats outside of protected areas, but in and around Mahamyiang Sanctuary, selectively logged forests (with dipterocarps removed) still contain many gibbons (Geissmann et al. 2013).
