Crash.

It was a relatively big bird this time, about pigeon sized. Smaller birds, such as sparrows would just leave a tiny splat mark. You know, kind of like when you throw an egg. The bigger ones, though, they can be quite problematic.

Jerry sighed as he heard the crash, slowly folding his newspaper. The more time he took to put the paper away bought time until he had to go assess the damage. He looked the window over, sure there was steam coming out of his ears. With a frustrated sigh, he called down the hall, "Damn it! We need to replace the window again."
