The black scoter or American scoter (Melanitta americana) is a large sea duck, 43 to 49 cm (17 to 19 in) in length. The genus name is derived from Ancient Greek melas "black" and netta "duck". The species name is from the Latin for "American".
Together with the common scoter M. nigra, it forms the subgenus Oidemia; the two are sometimes considered conspecific, the black scoter then being referred to as M. nigra americana. Its French name, used in parts of its Canadian range, is macreuse noire (also meaning "black scoter"). The species is listed as Near Threatened by the IUCN.
This large sea duck is characterised by its bulky shape and large bill. The adult male is all black with a very bulbous bill which is mostly yellow. The female is a brown bird with pale cheeks, very similar to female common scoter. The adult female averages about 980 g (2.16 lb) and 45 cm (18 in) in length, while the adult male is on average 1,100 g (2.4 lb) and 49 cm (19 in) in length.
This species can be distinguished from other scoters, apart from common scoter, by the lack of white anywhere on the drake, and the more extensive pale areas on the female. The black scoter... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Black Scoter is recorded against all the birds logged in Redwood National Park (106 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
