This is another idea.
They are not call shy, just educated a little. If you call from the same spot they figure it out. Change your setup location, like get below him, be further away than normal. Anything to give him something new. Do not call with the same calls and same sequence. mix it up and do not go loud. soft subtle calls along with scratching the leaves a little may be the ticket.

I think the best idea is to pattern him. But that can be boring. I would rather hunt another bird and have some action. I'll wait in my treestand all day for deer but not turkey.
