HabitatBreeds in wet tundra, bogs, sedge meadows, and open boreal wetlands. During migration and winter it uses mudflats, marsh edges, estuaries, wet fields, rocky shores, and muddy margins of ponds, lakes, rivers, and ditches, generally favoring sheltered, muddier ground over open sandy beaches.
BehaviorWalks slowly, often in a crouched posture, picking tiny invertebrates from the surface and probing damp mud with its bill. It commonly feeds in loose, relatively small flocks and favors slightly drier margins than other small sandpipers.
