I don't know about crows, but purple grackles are a problem here in the spring when literally hundreds show up at once. I usually spend about a week with a shotgun, by then they have decided to do their nesting elsewhere (they must fly off and re-group every time they hear the gun. I swear they do roll call - after the 20th or so casualty they call it quits) . Maybe next spring I will try hanging a dead grackle from a branch -
