Ring-necked Duck

Ring-necked Duck males are bold black-and-gray ducks with a dark head, black back, and gray sides with a white hash mark on the chest. Females are rich brown with a contrastingly pale cheek, a white patch near the bill, and a whitish eyering. Adult males have a prominent white ring on the bill. If you look close you can actually start to see the ringed necked.

Ring-necked Ducks are often in small flocks and pairs, diving to feed on mollusks, invertebrates, and submerged aquatic vegetation. Sometimes they flock with scaup; other times you may see them with dabbling ducks. Cornell All About Birds
