Habitat

Colonies restricted to coastal sites, typically located at heads of bays, reefs, permanent and ephemeral islands, estuaries in lagoons and at river mouths . Nests usually on grassy or mossy flats, sand spits, sandbars, sand dunes, pebbly seacoasts, vegetated summits of flat-topped islands, reticulate and string bogs, wet coastal marshes, or tundra (Haney et al. 1991, North 1997, Rosenberg 1986).
