I think camokenny has offered some great advice as well. I normally do the scratching thing once they start to come in and then hold up on me. The scratching sometimes gets them moving again. Some times there is very little you can do to get them to move again.

Hunting pressure is one part of why they fly back up on the roost again. At least here it is if an area is being hunted hard. That or they move back farther into the woods and will rarely show themselves. No answering calls or anything making one think they are not there. Then the moment they spot you it is into the air they fly. So that is when I try to find a clearing in the woods and try to locate some droppings in them. The turkeys will still strut and just a small opening can allow it for them.. I hope the info we have shared will help you out some.. Then again next year they may act better for everyone..
