If they annoy you guys with their cawing you need to move out of the boonies and into city where the pollution keeps their numbers under control.
I really like the crow. He's smart and misunderstood. Didn't you ever hear "Black bird" by the Beatles?
I do live in the city. We need a cull, pure and simple. Of course, they don't want to "upset" anyone, so instead they just waste our time(and tax dollars) shooting firecrackers and other noisemakers. All that does is stir them up for a little while and then go back to the same locations. If they do move, it's just a block or two away and it just makes it someone else's problem.
