The shrill single reed turkey call works better for fox and coyote than it does for turkeys when I blow on them. The fly down call never calls in turkeys for me in the morning, but I have had the coyotes come in fast. Went out coyote calling az few years ago with an expert. He had an antique hand siren that he could stick on his pick-up. Blue jays, crows, geese, foxes yipping, pheasants calling, turkeys gobbling, and coyotes everywhere, we didn't know where to begin. It was too cold for bows, so we crabbed are bang sticks and headed to a spot out of the wind. I had my rabbit call and my fawn bleat, but he wanted to try something first. . He used a silent dog whistle. I would have never thought that it would work, but I was glad that i took my 22 mag Ruger instead of my 308 auto. That day would have gotten expensive with the big gun. I think that i can hit a running coyote better with a bow than a scoped rifle.
