How can a Woodpigeon hit a window so hard to leave a dust print like this and just fly off? You can see the full extent of the wings, his head, eye, and beak. You can even see his feet at the bottom.
And no – there is NOT a window opposite this one giving the appearance of a straight-through path, this is just a particularly stupid pigeon. He’s done it before and took the whole day to recover. Maybe it was that collision that knocked out whatever tiny bit of sense he had.
