Patterning and ambush. Most of my fall birds have come home with me by knowing roost and feed travel routes or areas that are frequented by the birds.
Remember that right now, the birds will be in three distinct flock status: boys (jakes and toms), hens with their young of the year, and barren hens. So if you find a flock of birds, and see hens there, you can be fairly certain there will not be any toms running with the group. Later when the turkeys form up their "winter" flocks, everybody is joining in and will be all together. I have seen flocks of 100-400 birds in the depth of the wintertime.
Areas that hold birds in the spring can be devoid of turkeys in the fall/winter time, so don't assume that you can for sure find birds where you saw them in the spring.
There have been times when I inadvertently spooked a flock, or already killed my one fall bird (come one Kansas, let us have more than one fall bird!! ) and have made the "assembly" call of a mother hen, along with some kee-kee's or kee-kee/yelps of young of the year birds, and nearly been trampled by the inexperienced birds nearly walking over my outstretched legs. Its an amazing experience when you mouth whistle (kee-kee) and yelp and get those birds to huddle up on your sounds.
