SECRET WORLD OF SOUND WITH DAVID ATTENBOROUGH Sunday, 8pm, Sky Nature & Sky Showcase Factual (box set, Sky Box Sets/NOW)

Prepare to open your ears to life as you've never heard it before in Sir David Attenborough's new three-part series Secret World of Sound.

Using advanced audio technology, we get to hear birds that have mastered the art of mimicry and a baby caiman communicating from within an egg.

In this week's first episode, Sir David uncovers how animals use sound to catch prey and survive.
