White Handed Gibbon
Hylobates lar
Also known as the Lar Gibbon, they have a variable coat color, that varies from cream to black and dark brown to red; the variation is not related to gender or age.
They live in both primary and secondary tropical dry deciduous and moist evergreen forests. They eat 50% fruits, 30% leaves, 13% insects and 7% flowers. They, as all gibbons, use a special way of getting through the trees, it is called brachiation, going hand over hand, swinging from branch to branch, usually at speed.
They are monogamous, one male - one female plus offspring in a close family group. They spend virtually all their time high in the trees and they, as all gibbons, will defend their territory with violent aggression.
They have a melodic 'great call', the female starts and the male joins as she finishes.
They are found in pockets of forest in south east Asia, the Malay peninsula and northern Sumatra.
