Random I know, but....

there is this crazy bird flying to all my window ledges during the day tapping at the window with his beak and hitting it with his wing. I don't know what he thinks is in our house or why he's possessed, but he's really starting to freak kitty out! Go away silly bird. I've been trying to snap a picture of it, but once he notices I'm present, he flies away.****I hear him again!
