I'm of the opinion that a duck does not change styles every time it crosses a state line. I think they sound the same way from Canada all the way to the coast. As far as championship calling... I realize that a duck could not win a world championship, and that's why I don't do that. When it comes to duck calling, our judges have wings.
We only call at ducks when their rear ends are towards us. If I'm looking at you and you call my name, then I know where the sound came from. But if you had your back to me and I holler and you turn around, you would assume somebody hollered. You want your decoys to represent the sound that you're making.
