Purple Sandpipers are slightly larger and stockier than the related Dunlin. In their winter plumage (birds wintering on islands in Finnish waters) they have a dark grey appearance with short legs and a slightly curved bill. Their heads and chests are dark grey and their flanks are speckled. In flight they can be distinguished by their narrow white wing stripes and dark tails with white edges (tail pattern similar to Dunlin). Juveniles’ plumage resembles winter plumage, but the edges to feathers on their wings, backs and chests are yellowish, and their underparts have an orange tinge. Purple Sandpipers’ legs are greyish-yellow (summer) or orangish-yellow (winter), their irises are brown, and their beaks are blackish with colouring on the base varying from yellow to orange.
