If the Backstreet Boys are looking for a fifth member now that Kevin Richardson has left the group, they might want to check out a little cockatoo named Snowball.

Apparently Snowball has a "thing" for one of their early hits "Everybody (Backstreet's Back)." Push play and he sets off dancing. And this bird's got rhythm. It's pretty cute. Check it out here.

I wonder if any of the tunes on their new album, Unbreakable, due out Oct. 30, will catch Snowball's fancy. Guess we'll have to wait and see...
