Pigeons are definately poop machines. There is a pig farm near were I live and you can just imagine how many pigeons like to crowd around there, i feel bad for the people that live across the street from the farm. Their window sills are full of pigeon poop. There is this one pigeon in particular... hes big and black in color his hair (feathers) stand up instead of being flat and his feathers look like their full of feces. I think he tried to vomit on me once, I was sitting on a bench and i heard something like water smacking the ground right next to me, i looked and its definately not water, i look up and there he was. I believe he lives under a WAL-MART sign. He might be dead now im not sure, its been a while since i went to that particular WAL-MART but if he is dead, i imagine from disease.
Nice shot though.
