This question goes out to crow hunters. They are protected in some areas, but here in Kansas we have crow season. I recall about 40 or so years ago some older acquaintances would go out to call crows and take a case of shotgun shells. The number of dead crows would practically fill the bed of a pick-up truck. In my crow shooting life, my brother and I have been known to kill a dozen or two crows in one spot. Now when I call, I will get 2-3 shots, they get wise very quickly, and disappear. I also notice there seem to be more crows than ever. Have you veteran shooters noticed a change??
