Humans belong to a group called anthropoids. Gibbons have the most human-like traits among the anthropoids. Gibbons are the only apes capable to sing like humans and communicate through their songs. This film documents an unprecedented attempt to investigate the musicality of multiple species of wild gibbons - siamang, the white-handed gibbon and the javan gibbon - surviving in the South-East Asians habitats. The story of endangered Asian Ape unfolds in this documentary with their songs in various situations.
Unfortunately the movie The Singing Ape, Gibbon is not yet available on HBO Max.
