Experience

About

The Southern Yellow-cheeked Gibbon is one of Cambodia's most iconic primates and the flagship species of Jahoo. Famous for its haunting morning songs and remarkable agility, this endangered ape spends almost its entire life high in the rainforest canopy.

Unlike monkeys, gibbons are apes, meaning they have no tails and possess highly developed intelligence and social behaviors. They live in small family groups and form lifelong pair bonds, with mated pairs performing spectacular duets that echo across the forest at dawn.

Identification

Southern Yellow-cheeked Gibbons are easily recognized by their long arms, lack of a tail, and graceful movement through the forest canopy.

Adult males have glossy black fur with bright golden-yellow cheek patches, while adult females are light beige to golden in color with a distinctive black cap on the top of the head. Young gibbons are born with pale fur, turn black during infancy, and females gradually regain their lighter coloration as they mature.

Behaviour

Gibbons are among the most agile mammals on Earth.

Using a form of movement called brachiation, they swing effortlessly from branch to branch using their powerful arms, covering distances of up to 15 meters in a single swing.
