HabitatPrimarily salt marshes, tidal shorelines, mudflats, beaches, and flooded fields; also occurs around freshwater marshes and lakes in parts of its range. Usually remains close to water and may forage in nearby open or developed areas.
BehaviorGregarious and often colonial, with communal roosts. Walks on shorelines and through shallow water, rapidly probing and pecking for aquatic prey, insects, seeds, and other opportunistic foods. Displaying males fluff their plumage, spread the tail, flutter the wings, and point the bill upward while calling.
