People might like to sit and feed these animals, but they don't take into consideration the problems they can cause. Granted, they're not viscious but would you want them running around all over your workplace once they get used to being fed?
A similar thing is happening here. A neighbor of mine used to have homing pigeons. Well, he let them go, shortly before he became ill and passed away. There were always a few that would come around occasionally, but the stupid tenant in this guys house started feeding them. Now they're nesting on top of our houses, making sounds at the crack of dawn which is driving me insane, and just "messing" up the place. It's not so bad at my house, but my neighbor who is right next door to the house where the idiot lives...well...have you ever had to STEP over bird crap? I'm going to buy a pellet gun and solve this problem...
