The white-winged scoter (Melanitta deglandi) is a large sea duck. The genus name is derived from Ancient Greek melas "black" and netta "duck". The species name commemorates French ornithologist Côme-Damien Degland. The white-winged scoter is one of three North American scoter species and the largest species of scoter.

The male ranges from 1,360 to 2,128 g (2.998 to 4.691 lb) and from 53 to 60 cm (21 to 24 in), averaging 1,380 g (3.04 lb) and 55 cm (22 in). The white-winged scoter has a wingspan of 31.5 in (80 cm). This species is characterized by its bulky shape and large bill, which is feathered at the gape unlike the blocky bill base of the surf scoter. The white secondary flight feathers by which the species is named is visible in flight, but may be concealed when swimming.

GBIF citizen-science records
It is estimated from how often the American White-winged Scoter is recorded against all the birds logged in Minneapolis [Saint Paul] (13 verified sightings), 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.
