Can a bird dance? Yes, of course.

In fact, the influence of music on the brain is serious neuroscience research. From this article
From the perspective of neuroscience, listening to music is one of the most complex things you can do. Many parts of your brain have to work together to comprehend even the simplest tune.
What is the relationship between music, language and the brain? From this review of his seminal research HERE

From this interview of Aniruddh D. Patel at the NYT
First encounter with Snowball:
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.
So, never call a bird a derogatory bird brain anymore. :-)
