This text is about a biologist and conservationist Roger Payne. He discovered that whales sing and their songs can be heard across entire oceans.
Before he studied whales he had become an expert in animal acoustics. In 1967 Roger went to Bermuda where he met Frank Watlington. Frank told Roger about strange sounds that he had heard underwater. Frank thought the noises were coming from whales.
After that Payne and his colleague Scott McVay found out that the sounds were whales' songs which could travel across entire oceans. It happened at the time when hunters killed thousands of whales. Roger Payne released a recording of whale songs and it helped to start the 'Save the Whales' movement. In 1986 commercial whaling was banned.
Payne still is busy studying and protecting whales.
