I think you need to hunt. You cannot learn this kinda thing in a book or a movie. You can learn about it... and you can enhance your knowledge certainly. But starting fresh you have got to just drop in and do it. You will either get lucky, or like most of us, fail miserably.

Until you have some in the field experience, I don't think any of the lessons in any book or DVD will really stick, because you won't be able to recognise the situation that you are in with a particular bird. That isn't an insult at all, it is just a simple fact. Turkey hunting successfully has two really big key components (technique and holding still aside here)1) knowing the land you are hunting and the patterns of the birds intimately and (2) being able to recognise the situation you are in and draw on a pool of knowledge and experience to adapt to and succeed in that situation.
