If a gobbler is hot and reasonably close, don't even consider a move until you've exhausted your calling options. If all you've offered are yelps and clucks, toss in some cutting, cackling, fighting purrs, or even gobbling (if it's safe to do so) to light a fire under him. Switch your call types, too, from a box to a slate to a mouth call, for example. Often, the absolute best move is to give the bird a healthy dose of silence. Cats aren't the only things killed by curiosity.
