I look for a multitude of things.....droppings...gobblers have a j shaped dropping. Leaf scratchings in the woods are a good indication of where turkeys have been and might return to. Strutting zones, and dust bowls are always a nice find. Roost areas can be identified by feathers left behind. Tracks...generally speaking gobblers have longer tracks than hens. Food sources like grass, berries, and insects can be quite helpful to find as well.
