A dancing parrot named Snowball has shown researchers that birds really do dance to music. Dr Aniruddh Patel, of the Neurosciences Institute in San Diego, California, was so 'stunned' by a popular YouTube video of Snowball moving in near-perfect time to the Backstreet Boys' song "Everybody," that he went to see the sulphur-crested cockatoo in person. Patel increased and decreased the music's tempo and found that the bird is in fact listening to and following along with the beat. More info at ScienceNOW.
