American White Pelican
American White Pelican
Pelecanus erythrorhynchos
At a Glance
One of the largest birds in North America, with a 9-foot wingspan. Similar to Brown Pelican in shape but much larger, and very different in habits: Occurs far inland, feeds cooperatively in shallow lakes, does not dive from the air for fish. Despite its great size, a spectacular flier, with flocks often soaring very high in the air, ponderously wheeling and circling in unison.

Range & Identification
Migration & Range Maps
Most populations are migratory; some populations on Texas coast and in Mexico are permanent residents. Migrates by day, in flocks. Breeders from northern plains migrate southeast and southwest to coastal lowlands. Some nonbreeding birds remain through summer on winter range, especially in Florida. Strays wander widely, including to northeast.
Description
55-70" (1.4-1.8 m). W. 9' (2.7 m). Almost unmistakable. In high flight, looks all white with black flight feathers in wings; compare to Wood Stork and Whooping Crane. Early in breeding season, adults develop raised vertical plate on bill, shed later in year.

Songs and Calls
Usually silent; grunts or croaks on nesting grounds.

Habitat
Lakes, marshes, salt bays. In breeding season mostly inland, nesting on isolated islands in lakes and feeding on shallow lakes, rivers, marshes. Feeding areas may be miles from nesting sites. Also breeds locally on coastal islands. Flocks in migration stop on lakes, rivers. Winters mainly along coast, on shallow, protected bays and estuaries, also on large lakes in warm climates.

Behavior
Feeding Behavior
Forages by swimming on surface, dipping bill into water and scooping up fish in pouch. During breeding season does much foraging at night, locating fish by touch during frequent dipping of bill; by day, probably locates prey visually. May forage cooperatively, lining up and driving fish toward shallower water.
Diet
mostly fish. Primarily eats "rough" fish of little value to humans; also crayfish, salamanders.
Climate Vulnerability
Conservation Status
Colonies are vulnerable to disturbance and habitat loss. Total population probably declined through first half of 20th century, substantial increase since 1970s.
