Attack cardinal

Not much of a photo, but an interesting event.  I had been photographing flowers and hover flies at the nature center.  When I returned to my van a cardinal, who had been signing in the trees where I had parked, swooped down and started  pecking at his reflection in the side window of the van.  He did this several times, and I was able to get a snap shot of his behavior.  Got to watch out for those red feathered raiders!
