The yellow-cheeked gibbon is born blond and later turns black, and males carry this colouring through their lifespan and have the distinguishing golden cheeks; females are born blonde to blend into their mother's fur but they later turn black and turn back to blond at sexual maturity and only have a black cap on the top of their heads.[៣]
This diurnal and arboreal gibbon lives in primary tropical rainforest, foraging for fruits, using brachiation to move through the trees.
The yellow-cheeked gibbon, like all gibbon species, has a unique song which is usually initiated by the male.[ប្រភព?] The female will then join in and sing with the male to reinforce their bond and announce to other gibbons that they are a pair in a specific territory.[៤] The male usually finishes the song after the female has stopped singing.[ប្រភព?]
Little is known about this species in the wild, but it is thought that it has a life span of approximately 46 years.[៥]
A recent report by the Wildlife Conservation Society counted 2,500 yellow-cheeked crested gibbons in Cambodia’s Seima Biodiversity Conservation Area, an estimate that represents the largest known population of the species in the world.[៦]
