I also don't use decoys, and are usually in the woods. I've had it happen both ways with no consistency. If I have a bird I know is coming in I won't call to him within 50 yards or further if he's in sight. They're pretty good at pinning down pretty close to where that "hen" called from from a good distance, it always amazes me. Most of the ones I didn't know were real close when I called seem to be the ones that are more weary and cautious. I've had birds in close that periscope their neck up and you think uh oh, then all the sudden blow back up and continue strutting forward. I think a lot of people automatically think when he straightens up and runs his neck up that the jig is up and it's time to throw lead. I've been caught frozen quite a few times when I wasn't lined up for the shot and thought it was over by his body language only to have him drop right back into strut or just continue easing along.
