dumb bird! fly away!

For about a week now we have had this dumb bird thinking it is trapped in our garage. Why it can't just fly out the same way it flew in... I don't know. Everytime someone walks into the garage, it'll swoop at you. Dumb bird, I just want my garage back! Bird seed doesn't work. I know Uncle Nate has experience with birds in the house....Help us Uncle Nate!! hee hee
