Dark-handed Gibbon

Awesome calls from this creature!!! This video is poor, I admit but it's mostly for the fabulous calls. Just a km up Bukit Larut and we were entertained by these dark-handed (Agile) Gibbons. It is said that it's the females who call out with those high low dueting songs, mainly to claim their territory or to communicate to other mammals to stay clear.

The Dark-handed (Hylobates agilis) is also called the Agile Gibbon and found in the rainforests of Thailand, Malaysia, Sumatra and Borneo. I found a great paper done by Claire Thompson of the Anglia Polytechnic University on the vocalisations of the Agile Gibbon. Definitely worth the read.

Can't get enough of the calls so here's another bad video but with a bit of action.
