Lar Gibbon
The singing ape of Southeast Asia — long arms, hook-like hands, and duets that claim the canopy.
Endangered
Hylobates lar
Overview
Lar gibbons (white-handed gibbons) swing through the canopy with breathtaking brachiation, using arms longer than their legs. Mated pairs sing elaborate morning duets that advertise territory through the forest.
For Indonesia collectors, gibbons add a true lesser ape beside orangutans, proboscis monkeys, and slow lorises.
