When I was at college there was a huge grackle infestation on campus. You had to walk in the middle of the roads because if you walked on the sidewalk under the trees you would be wearing poo like this guy.

I remember knslyr was driving on campus once and had one finger out the car window, and it was promptly pooped on. LOL! Eventually they used air cannons to scare the birds off and they moved to the Governor's Mansion. Score!
