Laughing gull, laughing seagull or Leucophaeus atricilla is a medium-sized bush in North and South America. It breeds in large colonies along most of North America, the Caribbean and North Atlantic coasts of North America.

Black beaches in the summer are common in beaches and other coastal areas; Found from the east coast of the United States to Mexico and North-South America.

In the winter they retreat from the northern parts of their range and head to white with gray mist. Darker gray than other flowers of similar size.

The bills of the laughing gull are dark red in summer and black in winter. Stick to coastal areas, rarely find inland areas.

From the present placement of the leucophias following the Union of American Birds, the cheeks of laughter have long been kept in the genus Laras.

Name

The name of the genus Leucophius is derived from the ancient Greek leucos, “white” and phyos, “dusky.” Specific Atricilla Latin ater, from “black” and kila, “tail”. Linnaeus seems to have mistaken his note Attricapilla (black-haired), which would have been more appropriate for this black-headed, white-legged bird.

Range

Laughing gull breeds on the Atlantic coast of North America, the Caribbean, and northern South America.

Northern populations migrate further south in winter, and this species is a rare addition to Western Europe.

The English name for laughter derives from its violent K-ah call, which sounds like a high-pitched laugh “Ha… Ha… Ha… ”

The gulls breed, laughing at the ponds in the coastal wetlands and large colonies. A large nest of laughing gull made from grass is built on the ground. Three or four green eggs last about three weeks

Description

This laughing gull species is easy to detect. It is 36-41 cm (14-16 in) long, with wings of 98-110 cm (39-43 inches).

The adult laughing gull body of summer is dark gray on the back and white without wings and blackheads.

Wings of the laughing gull are much darker gray than all other similar flowers except the smaller Franklin's cheeks and they have black tips without the white crescent shown by Franklin. Chanchu is tall and red. The black hood of the laughing gull is mostly lost in winter.

On the sandy or rocky shores and salt-marsh islands along the Atlantic and Gulf coasts of North America, as well as in the Gulf of California and some Caribbean islands, and on these small, black-crushed hay bales or rocky shores and salt-marsh islands on the Pacific coast of Mexico.

Its light, breezy flight and lilting, smiling calls are a familiar sight and sound on these shores.

The breed has adapted well to human presence, gathered around a picnic group for handouts, followed by fishing boats, or waiting for ducks for fishermen. For many people along the Atlantic and the

Gulf Coast, the ridiculous calls and subtle tussles of this lovely cheek are the harbingers of spring. In mid-April the pair touched on sandy beaches or salt-marsh racks, their dark gray mantels silky and soft, their vivid black heads shining in the sun, their dark eyes covered with thin white-eyed crescent and they are exaggerated. And curious face-to-face performs a courtship dance all their own.

This gull is susceptible to human disturbance and prey throughout its reproductive cycle.

It avoids mammalian predators by establishing permanent mammal populations in contact with winter washovers.

The site selection of colonies and nests is sufficiently low and low to avoid predation and competition with nests and a consensus between nesting on higher islands sufficient to avoid water flooding.

The east coast jumping gulls have migrated south to the South Atlantic and the Gulf Coast to South America after a prolonged period of upstream and downstream delivery.

Pacific coast breeders spread north across the Salton Sea in northern California and migrated south from southern Mexico to Peru in the winter.

Laughing gull searches for habitat in their breeding grounds, such as shelters, alligators, and pickings on coastal shores. During winter many live in America south, feeding fish, crustaceans, worms, carrion, and garbage.

Originating from many coastal colonies in the late 1800s and early 1900s and by coastal trade, the laughing gull expanded its range and numbers in the early 20th century only to be destroyed later in the competition by expanding larger gulls to the south.

Today laughing gull is growing in most of its range, and is the most abundant breeding marine from the east coast of the United States, Maine to Florida.

The numbers of laughing gulls may change quickly. There and elsewhere, the laughing gull has adapted to feeding on the ground floor and airfields surrounding the airfield, in the field.

As a result, the species has been operated near major airports like New York City's John F. Kennedy. And breeding of endangered laughing gull ton islands in the Gulf of Maine is in close proximity to colonies (clutching eggs and adults).

Humorous flowers take three years to reach adulthood. Immature birds are always thicker than other similarly sized gulls except for Franklin. The first-year laughing gull is grayer at the bottom and has a slimmer head than the first-year Franklin, and the second-year can be distinguished by the wings layout and structure.
