As dawn arrives, forest birds claim their territories in the canopy. But there's one call which stands out among the rest, virtuoso of the forest symphony. It's a gibbon. Living on a remote mountain range in south central Yunnan is one of the few remaining wild gibbon populations in China. The black-crested gibbons of Wuliangshan. They are confined to these forest mountains, so remote and steep that few hunters ever come here.
