Secret World Of Sound With David Attenborough: Season 1

Animals use sound to survive: hunt prey, defend against predators, and escape danger. Great grey owls hear voles under snow. Kangaroo rats detect rattlesnakes by sound, drum feet to defend themselves.

Shrieking elks, humming fish, singing gibbons, and lyrebirds mimicking their surroundings all use their voices to find and attract a mate.

As baby animals take their first steps out of the nest, burrow, den or lair, the sounds that guide them could mean the difference between life and death.
