Steven Vecchio,
There's lots of good advise on here and many guys with boots on the ground intel. I first started hunting Kansas in the early 90's. This was during the height of the CRP program and very good numbers. Both Pheasant and birds aka quail. Us southerner's call a quail "bird"....If your willing to do some pre season scouting, make phone calls to local chamber of commerce, and get out and knock on doors for permission to hunt, you will be surprised just how much info you will get and that access to private land is still possible. Of course always be courteous to the landowner and you will get invited to hunt again. If your gunning for quail....birds are found thru out the state. Traditionally south east and south central Kansas held the best numbers. With the other areas following close behind. I would avoid north east Kansas as that area has lost most of the prime quail habitat that once made towns like Marysville, Seneca and Clay Center meccas for hunters. Try the southeastern area along with the Flint Hills. Pick a town that offers the amenities you want and get at it. If you want more of a mixed bag with pheasants as well, you will need to travel west. Imagine a diagonal line that runs from south central Kansas to north eastern Kansas...Salina was always my town that I used as a maker. If you want to find pheasants....go north, west or southwest of Salina.
And you will also find birds in the same fields. Milo is my favorite crop to work my setters, if there is weedy cover, plumb thickets and pasture or CRP adjacent, cock your gun and turn the dogs loose. A WIHA map is a great help to put you onto farms to hunt....private land that is open to public access.
And as you explore new areas, knock on doors or strike up a conversation with local farmers you may happen to meet at the caf?, hardware store or gas station. I friendly smile always helps! Good luck and get er done!
