Before moving to Florida I lived in Nashville. Black ducks were rarer like north Alabama I would assume but of course the first duck I shot with the plantation bottom gents along the old hickory river bottoms was a black duck. Growing up in southern Ohio i shot more black ducks than almost anything else. They were the hardest bird to decoy after sunrise but most mornings one landed in the decoys before shooting time and I jump shot a lot of them so they weren’t a big deal. More rice breast than any other duck.
