Key Differences Between Lesser Scaup and Ringneck Duck
Here are some of the main differences between lesser scaup and ring-necked ducks:
Bill Shape and Size
- Lesser Scaup: The lesser scaup exhibits a short and rounded bill, distinguished by its bluish tint.
This compact bill is notably smaller in proportion to its head, aligning with the duck’s smaller size. The bill’s tip is adorned with a subtle black marking, a key characteristic for identification.
- Ringneck Duck: Contrastingly, the ringneck duck boasts a tapered grayish bill. Notably, a distinctive white ring encircles the base of the bill, near its face.
While larger than that of the lesser scaup, this bill contributes to the ringneck duck’s unique appearance and aids in its differentiation from the lesser scaup.
- Lesser Scaup: The lesser scaup, as its name suggests, is characterized by its smaller size within the duck community.
Measuring between 15 to 18 inches in length and boasting a wingspan of 25 to 28 inches, this duck’s compact stature is reminiscent of the mallard. Its diminutive size is a key feature that aids in its differentiation from the larger ringneck duck.
- Ringneck Duck: In contrast, the ringneck duck exhibits a slightly larger size, while still falling within the range of medium-sized ducks.
With a length spanning from 14 to 18 inches and a wingspan of 24 to 29 inches, the ringneck duck stands out as marginally bigger than the lesser scaup. This size distinction plays a pivotal role in visually distinguishing these two species.
- Lesser Scaup: During the breeding season, the male lesser scaup showcases a distinctive pattern of plumage. It features a dark iridescent head, accompanied by a black breast and a subtle gray body.
This combination of colors creates an elegant contrast that enhances its aesthetic appeal. Notably, the lesser scaup’s back remains predominantly black, solidifying its unique appearance.
- Ringneck Duck: The male ringneck duck, in its breeding plumage, flaunts a captivating blend of black and white. The back and sides are dominated by deep black, while a striking white ring encircles its neck, lending the species its name.
The head is glossy black with a captivating purple sheen. This exceptional plumage, characterized by the white neck ring, is an unmistakable feature distinguishing it from the lesser scaup.
Habitat and Range
- Lesser Scaup: Both the lesser scaup and the ringneck duck exhibit a preference for freshwater habitats, such as lakes, ponds, and marshes.
However, the lesser scaup tends to be found in these habitats during migration and wintering seasons. Their wintering range spans across North and Central America.
- Ringneck Duck: Similar to the lesser scaup, the ringneck duck thrives in freshwater ecosystems like lakes, ponds, and marshes. It shares its wintering range with the lesser scaup across North and Central America.
Their overlapping habitat preferences underscore the importance of paying attention to additional characteristics for accurate identification.
- Lesser Scaup: The lesser scaup, like its counterpart, is a diving duck. It engages in diving behavior to forage for aquatic vegetation and invertebrates beneath the water’s surface.
This behavior is an adaptation that allows it to access its food sources efficiently, making it well-suited for its preferred freshwater habitats.
