Once it sees itself in one of the mirrors or a reflexion in a window, he'll spend how ever long he wants trying to chase his reflexion away. Freak spits all over the place, craps on everything he can smear. Same thing happens at work. The Admin building and the building I'm in have mirrored windows. When the light is just right and he sees his reflexion, he'll spend all day at it if he doesn't find my truck! This crapping has been going on for five years now. Last year I think he bashed his brain in - finally - because it was the damn female doing it. This year, there's another male. The NFL could learn something by studying these crazy birds!
