Man my friend was attacked by Pigeons in downtown Seattle a few months back. He was walking to work and a group of pigeons flew up in front of him and started dive bombing him and flying straight into him. He ran down the street to try and get into a building but the birds followed him the whole way.
A bunch of people watching called it in and the news crews all came and had stories about it on the 5 o'clock news.
Apparently there was a flock of rogue pigeons attacking people walking downtown all day.
