Description

The ring-necked duck is a diving duck 15-18 inches in length with a wingspan of 24-26 inches. It has a bump on the crown of its head, a slate gray bill with a white ring around the tip, and yellow eyes. It gets its name from the hard-to-see chestnut ring around its neck. The male has a glossy purple head that looks black. He has a black, chest, back, and rump, gray sides, and white stripes on the sides of his breast. He has a white stripe on his wings. The female has tan sides, a brown back, a white belly and a white ring around her eyes.

Range

The ring-necked duck breeds across Canada south through the northern U.S. and into northern California and Colorado. It winters along the Pacific and Atlantic Coasts and and the southern U.S. south into Mexico.

Habitat

The ring-necked duck is found in shallow wetlands with emergent, submerged or floating vegetation.

Diet

The ring-necked duck dives in shallow water for aquatic vegetation like wild celery, bulrush, pondweed and pond lily. It may also dabble on and just below the surface for food. It also eats mollusks, snails, aquatic insects, and small fish.

Life Cycle

The ring-necked duck pairs form in the early spring. The female chooses a nesting over or near the water in tall vegetation and builds bowl-shaped nest on a platform of vegetation and lines it with down. She lays 8-12 eggs. The male leaves when the female begins incubating the eggs. The female incubates the eggs for 28 or 29 days. The chicks fledge when they are about 50 days old.

Behavior

Unlike most other diving ducks, the ring-necked duck can take off from the water with running across its service.
