If you start your day on foot trying to strike up a gobbling bird, don't quit too soon. Keep at it. Ease through the woods, listening for yelps as well as gobbles (since hens might be around a gobbler), the sound of turkeys scratching in the leaves or their wing-beats. Stop and call every 100 yards, either with a locator or a sharp-pitched turkey call. A tom might not gobble if he hears you from a distance, but get close enough and your calls might force him to give his position away.
