NO UK STATUS / IUCN Red List: Least Concern
A bird that is only differentiated from it's relative the Greater Scaup on fairly subtle shape details, particularly in more ambiguous plumages like the one shown above. However, note the narrow head profile without big round cheeks, a feature that is typical of the greater when present. They feed by sifting through mud for molluscs, as well as feeding on aquatic plants.
