David Attenborough 7: Song Learning
When do song-birds learn their songs, and from whom? Are birds inventive? In a forest with many different species singing at the same time, why doesn't a bird learn the wrong song? W.H. Thorpe of Cambridge University, Peter Marler of Rockefeller University,
New York, Peter Slater of Sussex University, and John Krebs from Oxford University consider how birds acquire their elaborate songs.
