Siamangs are typically social animals, and they are monogamous meaning they mate for life. They live in a small group that consists of a bonded pair and their offspring. To claim a territory and strengthen the bond within their group, they will perform a unique song that lasts about 25 minutes. These series of calls, which consists or male and female parts, is known as duetting. A large throat sack sac inflates to enhance the quality of this song.
The siamang is known as the acrobat of the jungle for its movement by brachiation (swinging through the trees). A single swing can cover up to 10 feet in fact. They are very agile and live in high altitudes. When walking on a branch or on the ground, its long arms are held in the air for balance.
