HABITAT DESCRIPTION:
Nests in several colonies on the barrier islands (Portnoy 1981).

Nests locally on sandy ocean beaches on the barrier islands (Portnoy 1981), almost always in association with Royal Terns. Prefers warm fairly shallow waters such as bays and estuaries near large beaches and mudflats, but also forages by diving a distance out in the ocean and also by hawking insects in flight (Ehrlich et al. 1988)

Nests in an open area (Kaufman 1996) on bare sand above the high water mark, occasionally among shells (Ehrlich et al. 1988).

NATURE SERVE GLOBAL HABITAT COMMENTS:

Seacoasts, bays, estuaries, mudflats, river mouths, lagoons. In North America, nests with royal tern on unvegetated bare sand or sand-shell substrates on barrier beaches, sandflats, or dredge-spoil islands; sometimes in association with laughing gull or black skimmer. Colonies occur on dredged material islands in North Carolina, on barrier islands in South Carolina, both types of sites in Florida and Texas; the largest colonies in Louisiana occur on barrier beaches of Chandeleur Islands (Spendelow and Patton 1988).
