A Black Duck is a Black Duck. Collie, you are right, they are pretty rare down here in Louisiana. I've been duck hunting for 30 years and I have killed three, and two of them were in Arkansas. Two of them are on my wall. I went fishing on Okechobee onespring and there were Black Ducks all over the place. I was surprised to see that many during the spring. A Black Duck is a prize in the Miss. flyway.
