Red-cheeked Gibbon

Nomascus gabriellae 
 EN  Endangered (2015)

The Red-cheeked Gibbon (Nomascus gabriellae), also known as the Southern Yellow-cheeked Crested Gibbon or Buff-cheeked Crested Gibbon, is an endangered gibbon from eastern Cambodia and southern Vietnam. Gibbons from the genus Nomascus are all from the region that covers southern Yunnan, China to southern Vietnam, and the island of Hainan, China. They are all endangered or critically endangered species. The Red-cheeked Gibbon exhibits sexual dichromatism, like all Nomascus species. The male is black with blond cheeks and the female is blond with a black cap on the top of their heads. However, they are all born  blond to blend in with their mothers fur, and they all turn black later in their youth. The females turn blond again when they reach sexual maturity. This species is monotypic.
