Field notes

Appearance

Males display a dark purple-black head with a white breast band, grey flanks, and a thin white neck ring (often inconspicuous in field). Females are brown with a white eye-ring and faint neck ring; both sexes show a blue-grey bill with a black tip and subterminal white band.

Size and weight

Males 41–48 cm, 550–750 g; females 38–44 cm, 450–650 g.

Habitat

Ring-necked ducks inhabit freshwater lakes, ponds, and marshes with emergent vegetation and open water. They prefer smaller, shallower wetlands with adequate aquatic plants for diving and dabbling.

Distribution

Breeds across northern North America from British Columbia to Quebec; winters primarily in the southeastern United States, the Mississippi River valley, and the Pacific coast, with smaller populations in the Great Lakes region.

Diet

Ring-necked ducks dive for aquatic vegetation (pondweeds, coontail), seeds, and invertebrates; they also tip-up for surface plants and occasionally consume small fish and crustaceans.

Behaviour

Primarily crepuscular and nocturnal, especially on hunted waters; they are highly gregarious in fall and winter, forming loose flocks on open water and moving between feeding and resting areas at dawn and dusk.

Hunting tips

Scout open water at dawn and dusk to locate rafts; approach from downwind and use natural cover along shorelines. Ring-necks respond well to decoys on smaller ponds and will trade between nearby water bodies on regular flight lines—position blinds along these corridors during movement periods.
