Sounds of the Amazon rainforest at night - at first listen this seems like a thick wall of sound but once your ears get accustomed to the busy-ness, layers start to emerge.

You'll hear sounds like fog drip, soft wind and occasionally deadfall.

On top of that the piercing chorus of insects is constant, multi-layered and continuously changing.

As a final touch, several birds call every now and then, their plaintive wails echoing around the thick undergrowth.
