In low arctic, nests near upper edge of salt marshes along gently sloping seacoasts or broad estuarine deltas with abundant low graminoid vegetation. Breeds on coastal tundra, in low and barren terrain; on islands, deltas, lakes, and sandy areas among puddles and shallows, and in vegetated uplands.Often nest on islands in small ponds or river deltas, on small offshore islands, or on gravel spits. In mid and high arctic, nests near braided river valleys, deltas, and inland lakes (up to 30 km inland) (Reed et al. 1998). Typically rears broods in salt marsh <1 km from tidal areas (Sedinger and Flint 1991, Stickney and Ritchie 1996).
