bird i.d. sought: warning, pics of dead bird

I don't think birds do that
Glass windows, yes.

Poor bird.

I know, I was puzzled as well, but there's really no other logical reason why that bird ended up where it did. It does have some blood around its beak (and the tongue was out). The building is mostly concrete, but does have some windows up high. I'm not sure if the building has lights on at night, maybe it was somehow disoriented and flew into the window and ended up like that?
