first of all, major props for finally using that damn camera phone.
secondly, I am not sure what the deal is with with that bird. Might be dying. Might be having a bad bird dream. I've seen my fair number of dead birds on the streets and sidewalks, and none have been in a nice position like that, they always seem to die mid flight.
I was walking the dog this weekend, and some dick rag in front of me threw the last half of his movie popcorn right onto the street near some pigeons. Instantly, 95 other pigeons came dive bombing in to the popcorn massacre and the dog went nuts.
