A Bat!

I went to open the windows this morning to cool off the house and found a bat in between the window and the screen. Eek.

I don't have any idea how he (it?) got there. And I'm not sure how we're going to get it out of there - while making sure it doesn't get into the house. The current thought is to trap it against a bucket while we push the screen out. Then hope that the bat leaves so we can re-install the screen.
