The American White Pelican is a majestic bird species that's a delight to learn about. They're the largest waterbird in North America, with a wingspan of up to 9 feet.
These birds are expert fishermen, using their pouched bills to scoop up fish right out of the water. They can catch up to 4 pounds of fish in a single day.
American White Pelicans are highly social birds, often living in large colonies with thousands of other birds. They're also known for their impressive mating rituals, which involve elaborate displays of courtship.
One of the most impressive things about American White Pelicans is their ability to dive from great heights, sometimes as high as 60 feet, to catch fish in the water.
American White Pelican Fun Facts
The American White Pelican has one of the largest wingspans of any North American bird, reaching an impressive 9 feet.
They are pretty accomplished thieves, stealing from other pelicans and cormorants so they don’t have to do the work themselves.
White pelicans are one of the heaviest flying birds in the world, with an average weight of 7-20 pounds.
During the breeding season, male white pelicans develop a distinctive nuptial tubercle on their upper mandible, which makes them more attractive to prospective mates.
Females lay 1-3 eggs in a slight depression in the ground, which both parents will incubate using their giant orange feet.
White pelicans are skilled feeders, getting their food by dipping their beaks into the water to snag fish and other aquatic animals.
They breed on islands in shallow wetlands with many other birds, including other white pelicans and cormorants.
Only one chick usually survives to leave the nest, and they fledge when they are about 10 weeks old.
White pelicans are slightly larger than females, but the two sexes appear identical.
Description and Habitat
American white pelicans are an impressive sight, with their snowy-white feathers and distinctive black and white markings. They're a large bird, with adults reaching up to 5 feet in length and weighing between 10 and 30 pounds.
These birds are found in a variety of habitats, including brackish and freshwater lakes in inland North America. They can be found nesting on islands in remote areas, such as the rapids of the Slave River between Fort Fitzgerald, Alberta, and Fort Smith, Northwest Territories.
In the spring, American white pelicans migrate to Canada to breed, with approximately 180,000 birds making the journey each year. This is about 40% of the global population, and they can be found nesting from the coast of British Columbia east to Lake of the Woods and Lake Nipigon in Ontario.
American white pelicans are also found in the southern parts of their range, including southeastern Ontario and western Nevada. They winter on the Pacific and Gulf of Mexico coasts, from central California and Florida south to Costa Rica, and along the Mississippi River at least as far north as St. Paul, Minnesota.
In their winter quarters, American white pelicans prefer estuaries, bays, and lakes, and are rarely found on the open seashore. They can cross deserts and mountains, but generally avoid the open ocean on migration.
Behavior and Diet
American white pelicans are fascinating birds, and their behavior and diet are just as interesting. They don't dive for their food like some other pelicans, instead catching their prey while swimming.
Each bird eats more than four pounds of food a day, which is a lot of fish! The fish they eat can range from small minnows to 3.5-pound pickerels.
Typical fish prey include common carp, Lahontan tui chub, minnows, and shiners. They also eat other fish like Sacramento perch and yellow perch.
In addition to fish, American white pelicans eat crayfish, amphibians, and sometimes larval salamanders. They will even travel great distances to find better feeding grounds if they're on a saline lake with scarce food.
These birds are social and like to come together in groups of a dozen or more to feed. By cooperating and corraling fish, they can catch more food together.
However, they also steal food from other birds, a practice known as kleptoparasitism. They've been known to steal fish from other pelicans, gulls, and cormorants, and even from a great blue heron while in flight.

Both parents take turns incubating eggs for about a month. After the young leave the nest, usually only one has survived, and they spend the next month in a creche or "pod" learning to fly and molt into immature plumage.
The parents care for their offspring for another three weeks after they've fledged, until the young birds are ready to make their own way in the world.
Conservation Status
The American white pelican has a fascinating conservation status. It's protected by the Migratory Bird Treaty Act of 1918, which is a big deal for these birds.
Habitat loss is a major issue for American white pelicans, with flooding and drought being recurring problems. This can lead to nesting failure, which is a significant threat to their populations.
In the mid-20th century, the use of DDT, endrin, and other organochlorides in agriculture caused a pronounced decline in American white pelican numbers. This was a dark time for these birds.
A unique perspective: American White Pelican
However, after stricter environmental protection laws came into effect, populations began to recover. Today, there are more than 100,000 adult American white pelicans in the wild, with 33,000 nests in Canada and 18,500 nests in the US.
Shoreline erosion at breeding colonies remains a problem, and mass poisonings can still occur when pesticides are used near breeding or wintering sites.
