The marsh sandpiper (Tringa stagnatilis) is a small wader. It is a rather small shank, and breeds in open grassy steppe and taiga wetlands from easternmost Europe to central Asia. It resembles a small elegant greenshank, with a long fine bill and very long yellowish legs. Like the greenshank, it is greyish brown in breeding plumage, paler in winter, and has a white wedge up its back that is visible in flight.
