For only the third time in birding this county, I encountered 4 Black Duck today swimming with 4 Mallard on a section of the east prong of the Little Pigeon River in Jones Cove area of Sevier County. They were just downstream from the Dixon Branch Road bridge over the river. What seems different about this sighting is that the Black Ducks were on moving water, albeit, not a very big or fast running river; it's more of a lazy agricultural stream, but with wooded margins. Part of this is likely due to the many small ponds around here still frozen, but also in part, fortune. Keith Watson Pittman Center, TN
