Breeding habitat well-vegetated, permanently or semi-wet tundra from wet meadow to dwarf shrub meadow typically near marshy ponds, lakes, or streams (Parmalee 1992). In Alaska, also breeds on high, well-drained ridges (Holmes and Pitelka 1962). Nonbreeding includes grassy marshes, mudflats, sandy beaches, flooded fields, and shores of ponds and lakes (AOU 1983).
