Darvin Gebhart is a champion goose-caller. But there are also birds that use human language. Sparkie Williams was a famous parakeet, or budgerigar, that lived in England in the 1950s. He recorded commercials for bird seed and released his own hit single "Pretty Talk." Alex, the African Grey Parrot, was another notable talking bird, with amazing cognitive abilities.  Watch a video interview with Sparkie Williams and learn more about him at the British-Library.UK.
