Yellow-cheeked gibbon
Nomascus gabriellae
Yellow-cheeked gibbon is a primate in the family Hylobatidae (order Primates) — Nomascus gabriellae, recorded as Endangered.
Appearance
The yellow-cheeked gibbon, also called the golden-cheeked gibbon, the yellow-cheeked crested gibbon, the golden-cheeked crested gibbon, the red-cheeked gibbon, or the buffed-cheeked gibbon, is a gibbon native to Vietnam, Laos, and Cambodia. The yellow-cheeked gibbon is born blond and later turns black. Males carry this colouring through their lifespan and have the distinguishing golden cheeks.
Range and habitat
This diurnal and arboreal gibbon lives in primary tropical forest, foraging for fruits, using brachiation to move through the trees. Duetting occurs between mated pairs, the song is coordinated and contains sex-specific phrases.
The largest known population of this species is found in Cambodia's Keo Seima Wildlife Sanctuary, estimated at 1432 individuals in 2020.
