I phoned up the bird shelter in Indiana where Snowball lived and talked to the director who told me his story. A man had dropped him off with a CD and the comment, “Snowball likes to dance to this.” One day, Irena Schulz, the proprietor, played “Everybody” to amuse the abandoned creature. And Snowball began to move. Irena then made the YouTube video, which immediately went viral. Millions saw it.

“Let’s design an experiment to see if this is real,” I proposed to Irena, who had a science background herself. We took the Backstreet Boys song, sped it up and slowed it down at 11 different tempos, then videoed what Snowball did to each. For 9 out of the 11 variations, the bird moved to the beat, which meant that he’d processed the music in his brain and his muscles had responded. So now we had the first documented case of a nonhuman animal who, without training, could sense a beat out of music and move to it.

Now dance, bird!
