HABITAT DESCRIPTION:
Fairly common along the coast and barrier islands (Fussell 1994, Fussell and Lyons 1990). Strictly a coastal species (Hayman 1996).

Lives near oyster beds or clam flats in areas with extensive sandy or rocky beaches, tidal mudflats, and salt marshes. Nests among sand dunes, on islands in a salt marsh, or on dredge spoil islands (Hayman et. al. 1986, Kaufman 1996).

Nest is placed above the high water mark (Harrison 1975) in an open area among shells, gravel, and marsh grass on a sandy or gravelly substrate (Ehrlich et al. 1988).

NATURE SERVE GLOBAL HABITAT COMMENTS:

Rocky and sandy seacoasts and islands (AOU 1983); river mouths and estuaries, especially where rocks exposed at low tide; mudflats, salt ponds (Stiles and Skutch 1989).

Nests on the ground in open sites often on high parts of sandy beaches, also among rocks, on islands, on shingle beds, occasionally in saltmarsh (Harrison 1979, Harrison 1978, Shields and Parnell 1990). In marsh habitats, nested on sand in North Carolina, on sand, wrack, or grass in New York and New Jersey (Lauro and Burger 1989).
