The American white pelican (Pelecanus erythrorhynchos) is a majestic, soaring waterbird and one of the largest flying birds in North America. Instantly recognizable by its massive orange bill, expandable throat pouch, and flurry of snowy white feathers, it is a highly social bird that lives and hunts in large flocks. Unlike its coastal cousin, the brown pelican, this species does not dive from the sky to catch its food, relying instead on highly coordinated teamwork to herd fish in shallow waters.

Physical Characteristics and Size
The American white pelican is built for long-distance soaring and efficient surface-feeding.
- Size & Length: They are massive birds. Their body length ranges from 50 to 70 inches (130 to 180 cm).
- Wingspan: They boast one of the largest wingspans of any North American bird, measuring an incredible 95 to 120 inches (8 to 10 feet / 2.4 to 3 meters).
- Weight: Adults weigh between 10 to 30 pounds (4.5 to 13.6 kg).
- Coloration: They have a plump, snowy-white body and a long neck. Their distinct black flight feathers are tucked away when resting and are only visible when the bird’s wings are fully extended in flight.
- The Bill and Horn: Their iconic long beak features a massive gular pouch underneath, capable of holding up to 3 gallons of water. During the breeding season, the bill and pouch turn a vibrant, deep orange, and both males and females develop a unique, laterally flattened “horn” (nuptial tubercle) on the top of their upper bill, which falls off after the eggs are laid.
Geographic Range and Habitat
American white pelicans are highly migratory. They split their time between inland freshwater environments and warm coastal regions.
Preferred Habitats:
- Summer (Breeding): During the spring and summer, they migrate inland to breed on isolated islands in shallow freshwater lakes, wetlands, and marshes across the northern United States and western Canada.
- Winter: In the autumn, they migrate south in massive, V-shaped flocks to winter in coastal estuaries, bays, and warm-water coastal regions of California, the Gulf Coast, Florida, Mexico, and Central America.
Diet and Foraging Behavior
American white pelicans are piscivores (fish-eaters). Because they are so buoyant, they cannot plunge-dive underwater like brown pelicans. Instead, they feed entirely from the surface.
What they eat:
- Primary Diet: Small, schooling “rough fish” that have little commercial value, such as carp, minnows, suckers, and shad.
- Secondary Diet: Crayfish, salamanders, and tadpoles found in shallow wetlands.
Cooperative Hunting: They are famous for their highly coordinated, cooperative hunting strategy. A group of pelicans will form a semi-circle on the surface of the water. Beating their wings and splashing their feet, they work together to herd a school of fish into shallow water. Once the fish are trapped, the pelicans simultaneously dip their massive bills into the water, using their gular pouches like fishing nets to scoop up the prey and swallow them whole.
Reproduction and Nesting
American white pelicans nest in massive, noisy colonies, often alongside cormorants or gulls. They strictly nest on the ground of remote islands to protect their eggs from mammalian predators like coyotes and foxes.
The nest is a simple, shallow depression scraped into the dirt or gravel. The female typically lays 2 chalky-white eggs. Because pelicans do not have warm, featherless “brood patches” on their bellies like most birds, both the male and female take turns incubating the eggs by physically standing on them with their large, webbed feet.
The eggs hatch after 30 days. Usually, only one chick survives, as the older, stronger sibling often outcompetes or kills the younger one. The surviving chick leaves the nest at 3 to 4 weeks old to join a “creche” (a large group of young pelicans) and learns to fly at about 10 weeks of age.
Frequently Asked Questions (FAQ)
An American white pelican primarily eats small, schooling fish such as carp, minnows, and shad. They also occasionally eat crayfish and salamanders. Unlike brown pelicans, they do not dive for their food; instead, they swim on the surface and scoop up fish using their massive throat pouches.
During the summer, their habitat consists of shallow freshwater lakes and inland marshes across the northern United States and Canada, where they breed on isolated islands. In the winter, they migrate south to coastal bays, estuaries, and warm-water habitats along the Gulf Coast, Florida, and Mexico.
They are one of the largest flying birds in North America. They measure 50 to 70 inches in length, weigh between 10 to 30 pounds, and possess a massive wingspan that can reach up to 10 feet (3 meters) across.
No, American white pelicans do not plunge-dive. They are highly buoyant and feed while floating on the water’s surface. They often hunt cooperatively, forming a semi-circle to herd fish into shallow water before scooping them up in their bills.
