The attached map is the subspecies distribution within Kansas that is the results from genetics studies from Turkeys across the state. There are very few 100% pure sub-species anywhere in the U.S. as in the initial scramble to re-establish turkeys to their former range the most ideal sources were not always used/available. However efforts were made to maintain the subspecies as much as possible and there are several areas of the state and country with the genetics of one sub-species prevailing. Morphology alone (color of the bird) is not enough to judge a sub-species because there is a lot of variability among them just like in us. That is to say you may have red hair but there are many shades of red, just like there can be lighter and darker tail fans withing Rio's.
We have 3 hybrid zones in Kansas. The Flint Hills was the considered the historic boundary between Rio's and Easerns where hybrids were likely to occur. Given this during translocations to reestbalish Turkeys in Kansas West of the Flint Hills Rio's were released, East of the Flint Hills Easterns were released, and in the Flint Hills both were released. This created the Flint Hills as the hybrid zone. There was one exception where a group of easterns were released in Stafford county creating a small eastern population there with a hybrid zone around it. The reasoning behind the stafford county release is unclear.
We have no full Merriam's, the far southwest is the only area where merriams genetics were detected and the area is the Merriam/Rio hybrid. This is a result of Merriams from NM and CO naturally moving into the state and hybridizing with the released Rio's. There were a lot of samples taken from the Southwest and no eastern genetics were detected. There is a potential for a Rio/Merriam Hybrid along the NE boarder but was not detected in the analysis.
