O pato-fusco-de-asa-branca americano é um grande pato marinho do norte da América do Norte e Sibéria oriental. Distingue-se da espécie relacionada pelo bico com ponta laranja-amarela e tubérculo. Os machos são principalmente pretos com mancha branca abaixo do olho e remendos brancos nas asas visíveis em voo. Cria em zonas húmidas florestais boreais e hiberna em costas marinhas. Foi recentemente separado do pato-fusco-da-sibéria como espécie plena.
