The video that showed ‘Snowball’ on YouTube, around 2007, was quite a shock to me. That is to say: I thought of it as the first example of a nonhuman animal that had ‘beat induction’: the cognitive skill to synchronize or dance to the music.
Beat induction is a skill that none of our nearest relatives posses! Neither chimpanzees or bonobo’s can synchronize to the beat of the music.
However, Snowball - the Cockatoo- seems to be an exception. He could dance to the beat of Everybody of the Backstreet Boys like a grown-up human would do.
In the year that followed, Snowball became quite a celebrity. He appeared in the David Letterman Show and - together with its owner Irena Schultz - travelled all over the U.S., presenting its ‘skills’ at events like the World Science Festival (see link below).
