Mac tried keeping him away from the windows by putting moth balls around them. The bird didn't care. He put birdseed out for him, but the bird didn't care, Mockingbirds are bug eaters.
So the windows are closed, the blinds are down, the door is closed and except for a bird with what should be a sore head, all should be well.
NO! Tired of attacking the windows he moved on to the garage door and splattered it as well, as I said before, he is a pooh head.
