I have located them with the Hoot Owl Sounds without the call. In an Owl tone cupping your hands, it sounds like " Who Cooks For You, Who Cooks For You Alllllllllllll". The more you practice and don't get funny looks from your family members, the better you will get!
I do the same thing. I think my natural voice sounds way better than the owl calls you can buy. As far as turkey calling, I think I sound pretty good, but only killing 3 turkey I'm not yet willing to risk my chances.
