I Don't Mess W/ Pigeons

I won't cross the street when I see a bunch of pigeons but they do freak me out. Remember when there was a time when you could run into a large group of pigeons and they'd all fly away scared. Not anymore, now the pigeons don't even blink and a few of the bolder ones will walk towards you with a MF what attitude. So when I see pigeons chillin out together I leave them alone. It freaks me out when pigeons prefer to walk over flying .Why walk when you can fly, its almost as if a few are trying to evolve into walking birds. I don't think walking is an improvement over flying, though the pigeons walking across the street would probably disagree.
