2 Types of Pelicans in California

Brown Pelicans are smaller (up to 4 feet long) with dark brown and gray plumage, a distinctive white head with a bright yellow patch around the eye, and a gray or reddish pouch. They are designed for plunge-diving, with streamlined bodies and rapid wing strokes. American White Pelicans are much larger (up to 5.5 feet), with entirely white plumage except for black flight feathers visible in flight, a large orange-yellow pouch, and a long neck held in a gentle S-curve during flight. American Whites fly in coordinated flocks and dabble or dip-feed rather than dive, often working together to herd fish into shallow water.

The Brown Pelican is by far the most abundant, with over 44,000 iNaturalist observations recorded in California. Present year-round along the entire coast, they breed on offshore islands and feed in bays, estuaries, and open ocean. The American White Pelican, with nearly 20,000 observations, is highly seasonal, abundant from August through March, and rare or absent in late spring and summer. Most American Whites in California are migrants or winter residents, though a few summer locally. The Great White Pelican, recorded just once in California, is an extremely rare vagrant from Africa and Asia and should not be expected.

Yes. Brown Pelicans are the dark, compact pelicans you will see diving from the surface of coastal waters. Their brown and gray bodies, white neck, and bright facial pouch are unmistakable in good light. American White Pelicans are impossible to miss: snow-white bodies the size of a large goose, with black primary feathers that flash in flight, an enormous pouch, and a long neck. If you see a white pelican on California water, it is almost certainly an American White Pelican. When perched, Browns are stockier and darker; American Whites are taller, whiter, and more slender.

Brown Pelicans have a short, thick neck and a distinctive white head with a sharp demarcation between white and brown on the nape. Breeding adults develop an orange-red patch on the hind neck. The eye patch is bright yellow, and the throat pouch ranges from gray to reddish-orange. American White Pelicans have a very long, straight neck (held in an S when perched) and a small, neat white head. Their eye ring is pale yellow, and the massive pouch is bright orange-yellow. In flight, American Whites present an elegant silhouette with neck extended and wings set back; Brown Pelicans look compact and propeller-like.

Brown Pelicans are famous for their plunge-dives: they fly 20 to 60 feet above water, spot fish, adjust course mid-air, and crash-dive into the ocean to trap prey in their pouch. This spectacular behavior is visible from beaches and coastal overlooks throughout California. American White Pelicans rarely dive; instead they dabble, dip, or herd fish in shallow water, often working together in flocks to concentrate prey. American Whites prefer lakes, reservoirs, and protected bays where shallow water is available. If you see a pelican crashing into the ocean from the air, it is a Brown Pelican.

American White Pelicans are scarce in California from June to July but build rapidly from August onward, reaching peak abundance in September, October, and November. Numbers remain steady through winter and into early spring, then drop sharply from May through July. Peak observation months are September (6,173 sightings), August (5,925), and November (5,843). Inland reservoirs, particularly in the Central Valley and desert regions, are reliable spots from September through March. Coastal bays and estuaries host Americans year-round but in smaller numbers outside the migration season.

Brown Pelicans are common everywhere along the California coast and in major coastal bays. They are rare inland but occasionally visit large reservoirs. American White Pelicans are coastal but also frequent the Central Valley, Salton Sea, and desert reservoirs. Both species avoid small streams and high-elevation water. The best areas are tide pools and rocky coasts for Browns, and shallow bays and lake margins for Americans. Browns can be found from San Diego to the Oregon border; Americans are more concentrated in northern California and the Central Valley outside the coast.

Brown Pelican pouches are smaller and less conspicuous than those of American Whites, often hanging beneath the lower jaw like a storage sack. The beak is long and straight, slightly drooped at the tip. American White Pelican pouches are enormous, bright orange-yellow, and highly visible even from a distance. The beak is longer, straighter, and more robust, with a ridge down the center that is particularly obvious in breeding males. Holding the pouch inflated, an American White pelican can hold several gallons of water; a Brown Pelican's pouch is designed to trap slippery fish rather than hold volume.

Brown Pelicans are generally silent outside the breeding season, though they produce low croaks and grunts when interacting with other pelicans. Young chicks make loud begging calls. American White Pelicans are also mostly silent but emit deep grunts and occasional croaks, particularly during the breeding season and when competing for food. Neither species produces the loud calls associated with geese or cranes. Pelicans are visual predators that rely on sight and coordinated group behavior rather than vocal communication, so sound is rarely the first clue to their identity.

Brown Pelicans often gather in loose, strung-out lines following coastlines and riding wind currents, but true flocks of hundreds are uncommon. They sometimes loaf together on docks, jetties, and sandbars. American White Pelicans are highly social and frequently gather in flocks of dozens or hundreds, particularly during migration and winter. Watching an organized flock of American Whites in formation, with wings flapping in near-perfect synchrony, is one of California's wildlife spectacles. Browns prefer solitary or paired hunting; Americans actively coordinate to herd fish.
