Guide to North American Birds
Conservation status Numbers were seriously depleted during 19th century by hunting for feather trade, recovered well in early 20th century, then some decline at northern colonies owing to competition with larger gulls. Currently some colonies face threats, but overall population abundant and widespread.
Family Gulls and Terns
Habitat Salt marshes, coastal bays, piers, beaches, ocean. Generally found only in coastal regions, especially common around beaches and salt marshes, but also ranging several miles inland to rivers, fields, dumps. Found well inland in Florida and at Salton Sea, California. Nests on beaches and dredge spoil islands among grass and bushes.
The strident laughing calls of this well-named gull are among the most characteristic sounds around tidewater along the Atlantic and Gulf coasts, especially in summer. It seems to be mostly a warm-weather bird, with the majority departing from Atlantic coastal areas north of Florida in winter. Its nesting colonies are localized but often large, sometimes with thousands of nests.

Feeding Behavior

Forages while walking, wading, or swimming, or may forage in flight by plunging into water or dipping to surface. May steal food from Brown Pelican, landing on pelican's head and snatching fish from larger bird's bill pouch.


Eggs

3, sometimes 2-4. Olive to buff or brown, blotched with brown. Incubation is by both sexes, about 20 days. Young: Remain in nest for a few days after hatching, then wander nearby, hiding under vegetation. Both parents feed young, giving them half-digested food at first, solid food later. Age at first flight about 5 weeks.

Diet

Includes crustaceans, insects, fish. Diet varies with location and season. Eats many small fish, crustaceans, and insects, also earthworms, snails, refuse. In late spring, gathers to eat eggs of horseshoe crabs. Also eats eggs and sometimes young of other birds, especially Royal Terns.


Nesting

Breeds in colonies, sometimes with thousands of nests; sometimes associated with other species of gulls or terns. Nest site is on ground among grass or bushes. In more southerly areas, may be among denser growth, under shrubs or vines, perhaps for protection from sun. Nest (built by both sexes) may be a scrape in ground with sparse lining, or may be shallow cup of grass, sticks, debris, lined with finer grass. Adults may continue adding to nest during incubation.

How Climate Change Will Reshape the Range of the Laughing Gull

Audubon’s scientists have used 140 million bird observations and sophisticated climate models to project how climate change will affect this bird’s range in the future.
