Our little attack bird

We have a male cardinal at our house who likes to fight other male cardinals.  But none of the other cardinals who he fights are real! :)  He always fights his reflection in our living room, bedroom, and van windows!  He will be sitting on the porch railing, and then suddenly jump up and start fighting the other cardinal!  We hear a tap, bang, scratch, scratch and then he will retreat back to the railing only to attack a moment later with just as much force!  He is such a funny little bird!

I caught some shots of him in mid air fighting the window.
