Q. RECENTLY, YOU’VE BEEN WORKING WITH A SULFUR-CRESTED COCKATOO NAMED SNOWBALL. WHAT PROMPTED THE COLLABORATION?
A. Before I encountered Snowball, I wondered whether human music had been shaped for our brains by evolution — meaning, it helped us survive at some point. Well, in 2008, a colleague asked me to view a YouTube video of a cockatoo who appeared to be dancing to the beat of “Everybody” by the Backstreet Boys!
My jaw hit the floor. If you saw a video of a dog reading a newspaper out loud, you’d be pretty impressed, right? To people in the music community, a cockatoo dancing to a beat was like that. This was supposed to be, some said, a uniquely human behavior! If this was real, it meant that the bird might have circuits in its brain for processing beat similar to ours.
... [he describes the experiment they used to prove that Snowball was actually processing the music and dancing to it]...
We eventually published the Snowball research in Current Biology. A group at Harvard published a paper right alongside ours in which they surveyed thousands of YouTube videos to see if there were other animals spontaneously moving to a beat. They found about 12 or 13 parrots. No dogs. No cats. No horses.
