I killed one near the red river in Texas the spring of 1986. It looked like a domestic turkey from a distance. It was mixed with a large flock of wild Rio Grande turkey and I shot it thinking it was a domestic or a cross bred. Looking at it closer it wasn't actually white but light grey with darker grey markings. I had the local Game warden look at it. We both thought it was a cross bred but DNA testing proved it was a wild bird with an unusual color phase.
