I have called many into open fields and killed them midday high noon. When calling two people place the second persons watching the down wind side side of the person calling. Use a creek. Lake, road, field to try and get them to show themselves before they get down wind of you. Decoys can help. Keep the gun up at all times and be ready. They can come in fast. I've had them dead on the ground at the one minute Mark from the first call. About 45 minutes was the longest. 70% +/_ are seen shot the first 10.minutes. I also use all hand calls. Far as distress, they can all work at anytime, fawns, pup, rabbit, deer, birsd, cat, mix then up.
