His Own Worst Enemy

I had been watching this Northern Cardinal attack its reflection in the window of my truck for a while. When he saw the mirror, he became even more aggressive, so I took a few shots. He repeated the same sequence several times. Awareness of the male in the mirror, Attack!, Attack!, Attack!, Victory!

On a subsequent visit to that same spot about three weeks later, I was barely out of the truck when it started attacking again. I guess he just doesn’t like my truck.
