Nuthatch Bully

I was trying to get a video of this poor downy woodpecker trying to eat peacefully from the suet feeder, but ended up getting some interesting nuthatch footage instead. Watch the white-breasted nuthatch in the upper right corner. It goes through a series of displays to drive off the rose-breasted grosbeak. I was impressed: [youtube]http://www.youtube.com/watch?v=e76E9b4JOnE&feature=player_embedded[/youtube]
