There were releases of wild Eastern turkeys in the Cowlitz area years ago. Some reproduction, expansion and movement over the first few years resulted in birds being present in the Winston area. Since that time there have been consistent sightings here and there. Generally speaking if you see one of the wild birds (not the one with a bell on it) you're lucky. They tend to be pretty elusive for the most part.
There were also release made north and south of the Cowlitz areas during those years...north in like Thurston county south and south in like Kalama north. Lots of area with low densities equal....hard to find, unless you're willing to spend lots of time scouting pre-season.
