Uncommon and local. Breeds on arctic tundra; migrants occur in varied wetland habitats. Usually seen as singles or small groups. Feeds mainly by wading in fairly deep water, probing and picking with its bill, at times swimming. Note rather elegant shape, with long fine bill, long reddish legs (dark on breeding adults). Striking breeding plumage dark overall. Nonbreeding plumage is paler and grayer than smaller and chunkier Common Redshank. In flight often appears dark overall with narrow white oval up middle of back.
