In the depths of Thailand's Khao Yai rainforest, birdsong filters down from the dense foliage above like shafts of sunlight.
Bulbuls, barbets, drongos, flycatchers, doves and laughing thrushes are heard calling occasionally during their forays through the canopy. Meanwhile a soft susuration of insects permeates the tropical air, and from far off in the distance come faint hints of gibbon song.
This is a single, unedited recording; a spacious ambience that changes gradually as time passes.
