Barham recommends calling softly at first with just a few basic yelps. If nothing answers, he'll run through the series again, lending the calls more volume and a sense of excitement. Then, using the same tube, he responds with a gobble. This works to convince nearby toms-particularly dominant ones-that eager hens and competing males are nearby. For those hunters who have yet to master a tube call, you can perform the same call sequence using a diaphragm to make yelps, then use a gobbler shaker for gobbles. But don't overdo it, he warns. "Turkeys aren't doing a lot of calling at this time of year, so you shouldn't, either. You want everything to seem as natural to the gobbler as possible," he says. Instead, Barham remains silent for 10 or 20 minutes, sometimes even longer, before making more calls.
