The discovery of whalesong

Whales were being hunted to extinction, when in 1967, a biologist called Dr Roger Payne realised they could sing. It changed the perception of whales and helped found the modern conservation movement. Claire Bowes spoke to Dr Payne about his discovery in 2017. This programme is a rebroadcast.
