Spends winters on mudflats, salt marshes, and lakeshores along the West Coast from Washington south to coastal Mexico, along the southern Atlantic Coast, the Gulf Coast, and the West Indies. Preferred habitats include tidal flats and fields.

Breeding and Nesting

Semipalmated Plover: Three to four buff to olive brown eggs marked with brown or black are laid in a ground depression. In sandy areas, nest is lined with shell fragments and pebbles; on tundra, it is lined with plants. Both parents incubate eggs for 23 to 25 days. Young fly at 23 to 31 days.

They forage on mudflats or in shallow water, running and scanning for food in short bursts. They search for prey visually.
