Laughing gulls are medium-sized gulls with white underparts and a gray back. They visit the Chesapeake Bay in the summer to breed.
Laughing gulls have white underparts and a dark gray back. The wings are dark gray with black tips. The legs vary in color from dark orange to black. During the breeding season, laughing gulls have a black head and a deep red bill. In winter, the bill is black and the head is white with a smudge of gray. Immature gulls are variably colored, but are generally mottled brown and tan.
Laughing gulls eat a wide variety of foods, including fish, insects, mollusks and garbage. They will also hover over freshly plowed farm fields in spring to search for grubs. Laughing gulls sometimes eat the eggs of other bird species, but not as frequently as other gull species.
Eagles, herons, foxes, raccoons and domestic cats and dogs all prey upon gulls.
Laughing gulls hold their bill straight ahead while in flight.
Laughing gulls have a shrill, laugh-like call.
Reproduction and Life Cycle
Laughing gulls nest from late May to early August in sand dunes and salt marshes. They nest in breeding colonies with other gulls in groups of up to 25,000 pairs. Both male and female birds will help build the nest, although sometimes the male begins the process as a way to attract a mate.
Laughing gulls are monogamous and a pair can stay together for several breeding seasons. Females lay three olive to buff-colored eggs, which hatch in about 20 days. They reach maturity in three years.
