HABITAT DESCRIPTION:
Common throughout the coastal area (Fussell 1994) and barrier islands (Fussell and Lyons 1990).

Nests in salt marshes, especially those that are periodically mowed or burned, or where grazing by geese keeps the vegetation short (Johnsgard 1981). Often forages on sandy ocean beaches, especially after breeding season (Fussell 1994).

Nests on the ground, either among dense grasses or out in the open (Kaufman 1996). Usually spaced at least 200 feet from other nesting pairs, but can be as close as 40 feet (Johnsgard 1981).

NATURE SERVE GLOBAL HABITAT COMMENTS:

Marshes, tidal mudflats, beaches, lake margins, mangroves, tidal channels, river mouths, coastal lagoons, sandy or rocky shores, and, less frequently, open grassland (AOU 1983, Stiles and Skutch 1989). Nests along marshy lake margins in western North America, salt marshes in eastern North America. Nests on the ground in open places, coastal marshes, beaches, or islands; and inland in wet grassland by lakes, or short grass or bare ground by water.
