Northern Yellow-Cheeked Gibbon

DESCRIPTION

The fur coloration is very similar to that of the Southern Yellow-Cheeked Gibbon and cannot be reliably used to identify between the species. Males are black with cheek whiskers ranging in color from yellowish, deep orange hue and light brown, females are golden yellow with a brown to black patch on the crown of their head. 

GEOGRAPHIC RANGE

Found in Southern Laos, Central Vietnam, and Northeast Cambodia.

HABITAT AND ECOLOGY

The Northern Yellow-Cheeked Gibbon occupies broadleaf evergreen and semi-evergreen forest. They are predominantly frugivorous, but will also eat leaves, young shoots, and flowers. Similarly to the other crested gibbons they live in monogamous pairs with one to three immature offspring.

THREATS

The main threat to this species is hunting, predominantly for the pet trade, and to a lesser extent for traditional medicine and local consumption. 

STATUS AND CONSERVATION

The Northern Yellow-Cheeked Gibbon was described as a species in 2010; this is yet to be evaluated for the IUCN Red List and the 2007 Vietnam Red Data Book.

CITES Appendix I

This species is threatened with extinction and international trade is permitted only in exceptions circumstances.
