Yep,...hybridization is a fact of life for turkey hunters now that we have mixed all the paint colors together. Pure subspecies will eventually fade into a distant memory with only remnant pockets of "pure" birds in the most isolated spots. We have breached the geographic barriers that kept subspecies differentiation intact in the name of filling available habitat with turkeys. ...Good for turkey hunters,...but bad for subspecies distinction.
Oh well, the horse has dun been let out'a the barn,...ain't no goin' back,..so we might as well go huntin' and not worry about it. If you are concerned about killing a "pure" whatever,...go to the center of the most distant habitat where the subspecies have not been put together already.
