I was successful on the very first day of my very first fall hunt almost 4 decades ago. I was invited to be a guest at a camp to hunt fall birds, so never hunting them before, off I went to a local sporting goods store to buy a turkey call. Guy at the counter showed me how to yelp and cluck on a Smith's all butternut box. He gave me the advice to just mimic what I heard the birds doing if I got into a flock.
An old timer at the camp told me that the oaks and cherry were plentiful on a ridge and I headed that way. I set up at a tree, and waited, trying that yelp call I just learned now and then.
A shot rang out a couple hundred yards above me late morning, and suddenly turkeys were scattering down into the hollow where I was. About 30 minutes later, I heard a yelp, then another, then a kee-kee, and more kee-kees, and more yelps, a half-gobble, and lots of yelping all around me. I yelped again and here they came. Bang.
This is easy I thought.

It is when someone else does all the hard work of finding a flock, and getting a good break on them.
Eggshell gives terrific advice. Follow the mast crop, look for scratchings on the ground. Those scratching will show you the general direction the flock is headed, and be patient. If there's snow on the ground, well the tracking job just got way easier.
The bust is key - you either get it right and they go in all directions, or you mess up and they all fly or scoot off in the same general direction. Once the break is done, sit down in the middle and wait quietly until they start calling to get back together. Mimic what you hear, but with a little more urgency and intensity. Little practice you'll figure it out.
