The siamang is an arboreal black-furred gibbon native to the forests of Indonesia, Malaysia and Thailand. The largest of the gibbons, the siamang can be twice the size of other gibbons, reaching 1 m in height, and weighing up to 14 kg. The siamang is the only species in the genus Symphalangus. This one is usually screaming loudly but today it was silent while swinging thru its playground. Unfortunately the show was backlit.
Good action shots.
