Male and female pairs "duet" each morning shortly after dawn to reinforce their pair-bond. Here at the zoo, we have two separate islands with one pair on each, and the two couples "duet" back and forth between the two islands.
Lar Gibbons have no tails. They normally stand, or sit, upright. Their shoulders and wrists are very mobile. The arms are generally long, mostly longer than the legs. These gorgeous creatures move in a process called brachiation - an arm-hanging, hand swinging method of movement between branches.
