Siamang

Symphalangus syndactylus

Animals of All Regions Back
Siamang’s live in a small family group consisting of the monogamous breeding pair and their offspring. Like all gibbons, siamangs have a great call that can be heard up to 2 miles away through the forest. During the call, siamangs will inflate their throat sac, helping to make them the loudest of all the gibbons. In the morning, an adult female will begin hooting and soon after the rest of her group will join. This is used to warn other siamang groups of their territory. Paired siamangs will also partake in “duets,” with the male screaming booms and the female producing barks.

Both the male and female share the duty of raising babies. For the first year of the offspring’s life, the mother will provide most of the care. During the second year, the father will begin to take over some care, if not all of the responsibilities. That is more or less around the same time when the youngster will be weaned.

Siamangs move through the forest via brachiation. Their extra-long arms—with an arm span of almost 5 feet—give them the ability to cover up to 10 feet in a single swing!
