Like RDHunter was saying...call at them. I would call at the last second of the day when you know they have flown up or early, early in the morning while they are still on the roost. That way you have a better idea of exactly what group of trees they are up in!

Just remember when you're hunting don't call too much. Use your watch to make sure you are spacing out your calls enough, I'd say 15 mins. If you got a gobblergobbling I would go quiet except maybe scratching theground. See if he comes in.After a while I'd give it a light cluck or two andalways be looking around, he may come in silent. Biggest mistake most new hunters make is over-calling. Also, shock gobbling may not work. Where I hunt there are tonsof birds,and they don't gobble on the roost for owl/crow/coyote/woodpecker calls. They are there but theyjust don't respond tothose calls. Not sure why. Good hunting.
