I certainly understand the problem, but I simply cannot agree with the mass extermination methods . I know it's a purely emotional stance to take but in some things I just can't help but let my emotions influence my opinions when it comes to something like this.

As far as pigeons, I always thought they were not native to North America but were brought over by people, originally domesticated for carrying messages and pets etc. I could be wrong though, I've not done any true research on that.
