Tweet of the Day is the voice of birds and our relationship with them, from around the world.
Sir David Attenborough presents the superb lyrebird of eastern Australia. Superb lyrebirds are about the size of pheasants. During courtship, as the male struts and poses, he unleashes a remarkable range of sounds. Up to 80% of the lyrebird's display calls are usually of other wild birds. However, if kept in captivity, they can mimic a chainsaw, camera click, gunshot and a whole host of other man made sound. Research recently discovered that the lyrebird co-ordinates his dancing displays to particular sounds. But superb lyrebirds are promiscuous performers and it's quite likely that another male may have played the leading role while he dances and sings away.
