“When a man has pity on all living creatures then only is he noble.” —The Buddha (6th cent BCE)
A gibbon family has a territory of about 30 to 50 acres of old-growth rain forest. Each morning upon awakening a family group of gibbons loudly announces its presence in the forest, using a territorial hooting call and menacing gestures. This call warns other gibbons to stay out of their territory (and especially away from the local fruit trees). This noisy display takes 1/2 hour or more every morning and is usually started by the adult female. The male and female have different calls.
The siamang, the largest and darkest species of gibbon, has an inflatable throat sac (called a gular sac). This sac can be inflated to be as big as the siamang's head. It acts a resonating chamber for the vocal chords, making the sounds even louder.
