Siamang: The Loudest Gibbon of Southeast Asia — Premium Wildlife Guide

Meet the Siamang — Southeast Asia’s Most Vocal Primate

Before dawn breaks over the rainforests of Sumatra and the Malay Peninsula, a sound erupts from the canopy that carries for up to 4 kilometres — the haunting, booming duet of a siamang pair. The siamang (Symphalangus syndactylus) is the largest of all gibbons, and the most vocal primate in Southeast Asia. Inflating a remarkable grey throat sac to the size of a grapefruit, siamangs produce calls of extraordinary power and complexity that reinforce pair bonds, advertise territories, and fill the forest with one of nature’s most dramatic soundscapes. This premium digital guide takes you into the rainforest canopy to explore the world of this magnificent lesser ape.
