For dirt to stick to a window that thickly it'd have to be a pretty good build up over time, and in my opinion wouldn't make such a clear impression, unless the bird that hit it was wet (which would possibly explain the navigational problems).

Either way I don't really care. That's just what I think.

We often get birds whapping our windows and glass door. Once a big ass bird hit the door and it sounded like a tennis ball. That evening as the sun set the light hit the door just so and you could see a really clear outline of the bird in what appeared to be dust. (maybe dust baths?) Feathers and all. It was only visible when the light hit it at an extremely acute angle.

Did I take a picture of it?

D'oh!
