Behavior
An inconspicuous bird of dry sandy beaches. Breeds in open sand, gravel, or shell-strewn beaches and alkali flats. Nest site is typically near small clumps of grass, drift, or other windbreak. In winter prefers sand beaches and mudflats. Migrants seldom seen inland but occasionally show up at lake shores, river bars, or alkali flats. Forages visually in typical plover fashion, employing and run-stop-scan technique. Captures prey by leaning forward and picking at surface. Also employs a "foot-tremble" feeding method, causing prey to move and become more conspicuous. Feeds by day and night. Eats a wide variety of aquatic marine worms, insects, mollusks, and crustaceans. Seldom found in large numbers except at a few favored wintering or staging sites, where numbers sometimes reach 100 or more. More typically seen in pairs or in groups of 3 or 4. When approached, more often runs than flies. Very aggressive when nesting.
