If you do some searching on youtube using terms such as: 'parrot mozart', you'll find, of course, lots of people who've posted their favourite pet shots. What is very interesting is that some of these birds show evidence to my ears of binary form. And they take themes from Eine kleine nachtmusik or The Queen of the Night aria and vary them in a birdlike fashion: taking melodic units and changing them. I read a few years ago about how some songbirds were compared to Beethoven for their methods of composition. The author stressed that these were often inherited traits; and so they weren't really Beethovens. I don't think some of the Amazonian parrots you'll find on youtube have Wolfie in their genes.
One can spend a good few hours analysing parrots on youtube. I think the video must make it almost as much fun as it was for Messiaen with his LPs. Happy listening!
