Do you know where he is bedding? If so find his transition route from bedin thecover vs trying to figure him out in the open. I'd be looking for a trail that may run him parrellel to the field inside the bush and shadows. He might actually come to the same spot every time from bed butjustmoves alongatrail inside the bushlineand pops out in the actual open when feels safe or picks up a scent he wants to investigate.
