That is crazy, especially if it is the same bird. There must be something in your house it likes. I've had birds do this at my house but not all the time. I actually had a cardinal and a goldfinch to die hitting one of my windows. I put some decals on it and it seems to have helped.
Welcome, to Whatbird, ger! Are those your intitials or do you like to growl? ;)
