If it were ever proven that parrots are the most musical of animals, then David Preece’s pet may be used as evidence. Ollie the African Grey parrot regularly whistles along to a piano nearby. He became an internet hit after the Facebook page of birdtricks.com shared his 2011 video of the parrot whistling along to Always Look on the Bright Side of Life. It has now been seen over 40,000 times. Credit:YouTube/DandTbird.
