When I was a youngster I did this a lot (sort of). I had a crow call and would go into the clear-cut above our house. I would call at crows, and every now and then I could get them in range and I would pop a couple with my 12 ga. Then I had a long length of skinny grey pvc to which I would zip-tie a couple of dead crows. I would shake this up and down and the dead ones would sort of flap their wings.

Combine that with a few other dead crows placed on stumps or limbs and the crow call. I could get lots more crows.

I even had a few blinds placed around this clear cut for my activity. Seemed like a good waste of time at that age (13-14).
