Ring-Necked Duck (Aythya collaris)

Ring-Necked Duck

Description
Ring-necked ducks are similar in appearance to scaups. In flight, the dark wings are different from the white-edged wings of scaup. Faint brown ring on drake’s neck never shows in the field; light bands at tip and base of bill are conspicuous.

Average Size
Ring-necked ducks have an average length of 17 inches and an average weight of 2 1/2 pounds.

Range
While found in all 4 flyways, ring-necks are most common in Central and Mississippi flyways. Ring-necked ducks are winter residents in South Carolina.

Preferred Habitat
In the summer months ring-necks are commonly found in shallow, freshwater wetlands such as marshes, fens, and bogs that have an acidic to near neutral pH. In the winter months they can be found in a variety of freshwater wetlands such as swamps, backwater areas, sloughs, marshes, freshwater impoundments, and flooded agricultural areas.

Typical Flock Pattern

Food Habits

The diet of the ring-neck is dominated by aquatic plant seeds, tubers, and aquatic invertebrates. During the breeding season they increase their intake of animal foot such as mollusks, snails, and earthworms.

Reproduction

Pair bonds form during spring migration. Nests are built over water in dense emergent vegetation. The female constructs a simple nest bowl of sedges and other plant material. Once the nest is complete the hen lays 6-15 olive buff eggs.

Sound

Drakes purr, and hens are usually silent.

Miscellaneous

  • Fly as small flocks in open formation; often land without circling.
  • Drake is not territorial, but will defend immediate area around female.
  • Found in small flocks during the winter months.
