My buddy Bill And I used to hunt crows by jump shooting them when they were on the move. Crows never seemed to fly very high. So the game was to figure out where they were going to go next and then pick an ambush spot. Gullies, ditches, dips, wood lots, anywhere that offered cover. Bill used a 30 inch Parker FxF and I used a model 12, both in 12 ga. Bill did this trick where he reversed two shells in his left hand, he was right-handed, he’d fire twice, hit the open lever and snap the barrels down and pop in those two shells and snap the barrels closed. He could get off four shots in the same time I could get off five. That was nine rounds pretty quick like. Most we ever got was three crows in one jump. By the end of two years all the crows within a five mile radius were pretty leery of us.
From what I have heard about...they recognize the faces of people. And they communicate with each other as to who is present.and who is “safe” for them.
