Silvery gibbons are easily recognised by their long, fluffy, silver-grey fur and fringe-lined faces!

A silvery gibbon’s time is spent scaling the rainforest tree tops foraging for fruit and leaves. The small family groups move quietly through the canopy and a moving branch or falling piece of fruit is usually the only sign they’re above!

Silvery gibbons are quite vocal using their loud calls to mark their territories and protect their borders from neighbouring groups. They have varied vocalisations for communicating to each other and they’re the only gibbon species that don’t sing in duets.

Family groups consist of several juveniles with mature offspring eventually leaving the family to find their own territories.

Female silvery gibbons come into their Estrous cycles at any time of the year – these Lesser Apes do not have a breeding season. After a 7 – 8 month gestation period, a single young is usually born and stays with the family around 8 years.
