Turkeys have predators that attack them from the air, not so much the truth for deer. Turkeys tend to look up a lot more often than deer because of this fact. That being said I did call a hen and her flock in out of a treestand in fall one year, but I wasn't hunting them, so moving to get in position wasn't an issue. I would also suggest not using a scope on your turkey gun. I, like mudhen, like to see what is happening around the bird that I'm working. I started hunting turkeys ten years ago, and it is my favorite species to go after.
