ヨーロッパクロガモ

<em>Melanitta nigra</em>, the common scoter, is a sea duck in the family Anatidae, order Anseriformes, breeding across subarctic and boreal regions of Europe and northeastern North America. This species winters primarily along coastal marine environments, with records from Belgium, Denmark, Norway, Sweden, and the United States reflecting both breeding and wintering distributions. The common scoter typically nests near freshwater lakes and bogs in boreal and tundra habitats, migrating to sheltered coastal bays and estuaries during winter where it dives for bivalves, crustaceans, and other benthic invertebrates. Males are predominantly black with a characteristic orange-yellow knob at the base of the bill, while females are brown with pale cheek patches. <em>Melanitta nigra</em> is listed as Least Concern by the IUCN, though populations have experienced declines in some regions due to changes in wintering habitat quality and food availability. Biological traits for this species remain poorly documented in the scientific literature, including comprehensive data on average lifespan, body length, weight, and full dietary composition across seasons.
