Laughing Gull
Laughing Gull
Leucophaeus atricilla
At a Glance
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.

Habitat
Salt marshes, coastal bays, piers, beaches, ocean.

Behavior
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.
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.
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.
Conservation
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.
