The Laughing Gull (*Leucophaeus atricilla*) is a strikingly charismatic seabird of the Atlantic and Gulf coasts, named for its distinctive, raucous "ha-ha-ha" call that sounds like maniacal laughter. In breeding plumage, it sports a sleek black hood, a crisp white crescent above the eye, and a dark gray back contrasting with pure white underparts, while its legs and bill are a vivid deep red. A special feature is its seasonal transformation: in winter, the black hood fades to a smudgy gray, and its bill turns black. Highly adaptable and opportunistic, it is known for its kleptoparasitic behavior—boldly stealing food from other birds—and its remarkable ability to drink seawater, excreting excess salt through specialized glands near its eyes.
Fun Facts
True to its name, the laughing gull produces a loud, piercing "ha-ha-ha" call that sounds eerily like human laughter, often given in chorus during colony disputes. It is a master of kleptoparasitism, aggressively chasing smaller seabirds to force them to drop their freshly caught fish, a behavior so brazen it has been observed stealing food right out of the beaks of terns mid-flight. Unlike most gulls, it undergoes a dramatic seasonal color shift, molting from a dark, black-hooded breeding head to a stark white winter head with just a faint smudge behind the eye. Remarkably, it is one of the few gull species that regularly forages by "pattering"—rapidly tapping its feet on mud or shallow water to mimic raindrops and lure earthworms or invertebrates to the surface.
Habitats & Distribution
The laughing gull is a coastal species primarily found along the Atlantic and Gulf coasts of North America, with its breeding range extending from Maine south to Florida and west along the Gulf Coast to Texas and into the Caribbean and northern South America. It inhabits sandy beaches, salt marshes, estuaries, and barrier islands, often nesting on low-lying, sparsely vegetated ground near water. During the non-breeding season, it disperses more widely, ranging south to Central America and northern South America, and is also common along the Pacific coast of Mexico and Central America, where it frequents harbors, mudflats, and coastal lagoons. This gull is highly adaptable, often found near human activity such as landfills, parks, and fishing piers, but it avoids dense forests and inland deserts.
Behaviours & Reproduction
Laughing gulls are highly social and breed in dense colonies, often on coastal islands or salt marshes. Their courtship involves elaborate aerial displays, head-tossing, and a distinctive long-call vocalization where the bird throws its head back. Pairs are seasonally monogamous, typically reuniting each breeding season, and they build a simple scrape nest on the ground, sometimes lined with grass or shells. Both parents share incubation duties for about three weeks. A unique reproductive strategy is their frequent practice of "egg dumping," where females may lay eggs in the nests of neighboring pairs, increasing their reproductive output at the expense of other parents. Chicks are semi-precocial, leaving the nest within a few days, but they remain near the territory and are fed by both parents until they fledge at around five weeks.
Diet
The Laughing Gull is an opportunistic and highly adaptable omnivore, with a diet that shifts dramatically between inland and coastal environments. While foraging along beaches and marshes, it primarily feeds on small fish, crabs, shrimp, and marine worms, often scavenging dead fish washed ashore. On land, it is a notorious kleptoparasite, stealing food from other birds like terns and pelicans, and it will also hunt insects, earthworms, and even small rodents. A particularly interesting fact is that Laughing Gulls have learned to follow plows in agricultural fields to feast on exposed grubs and worms, and during nesting season, they are known to raid the nests of other seabirds, consuming eggs and chicks. Additionally, they are one of the few gull species that regularly eat fiddler crabs, skillfully extracting the edible parts while discarding the shells.
Colors
The Laughing Gull has a black hood and white nape in breeding plumage, with dark gray wings, black wingtips, and a white body. In winter, the hood is lost, leaving a smudgy dark ear spot and a white head. Its bill is red-black, and legs are black. No specific camouflage adaptations are notable; the white underside countershades against the sky when viewed from below.
