HABITAT DESCRIPTION:
Nests only in a few sites on small, uninhabited coastal islands (Potter et al. 1980). Common on the Outer Banks (Fussell and Lyons 1990); less common in western portions of Pamlico and Neuse estuaries. Population is increasing (Fussell 1994).

Nests colonially on sandy, rocky, or mangrove-covered islands and forages in the ocean or the sound (Kaufman 1996), especially near inlets and salt estuaries (Fussell 1994).

Nest may be located on the ground or in the top of a tree. Foraging is done colonially, by diving from a great height into the water. Pelicans will also scavenge food from fishermen (Ehrlich et al. 1988).

NATURE SERVE GLOBAL HABITAT COMMENTS:

Mainly coastal, rarely (becoming more regular?) seen inland or far out at sea. Feeds mostly in shallow estuarine waters, less often up to 40 miles from shore. Makes extensive use of sand spits, offshore sand bars, and islets for nocturnal roosting and daily loafing, especially by nonbreeders and during the non-nesting season. Dry roosting sites are essential. Some roosting sites eventually may become nesting areas.

BREEDING: Nests usually on coastal islands, on the ground or in small bushes and trees (Palmer 1962). Nests on middle or upper parts of steep rocky slopes of small islands in California and Baja California; usually nests on low-lying islands landward of barrier islands or reefs on Atlantic and Gulf coasts, where often nests in mangroves, sometimes in Australian 'pines,' red-cedars, live oaks, redbays, or sea grapes. In the subtropics and tropics, mangrove vegetation constitutes an important roosting and nesting substrate (Collazo and Klaas 1985, Schreiber 1979, Schreiber and Schreiber 1982). May shift between different breeding sites, apparently in response to changing food supply distribution (Anderson and Gress 1983) and/or to erosion/flooding of nesting sites.
