Stem can turn without breaking
The sounds of gibbons past: a duetting pair of gibbons. Recorded some time between 22/6/96 and 4/7/96. Location: somewhat north-east of the location marked on the map. This is my oldest recording of gibbons.
Duetting pair — mainly the male was singing. In this excerpt, the female sings first, followed by the male.
