Siamangs calling, Woodland Park Zoo
Vocalizations
Gibbon families typically “sing” a territorial song in the morning, and sometimes at other times of the day, to announce the borders of their area to neighboring gibbons groups. This call is also a mechanism for social bonding. Zoos with multiple gibbon groups will often observe gibbons counter-calling. The start of one group’s call will often prompt a response call from the other group.
