Is a seagull a bird?

Introduction to seagulls in a broad sense:

More than 40 species of seabirds with stout bodies and webbed feet belonging to the subfamily Larinae (Laridae). The most species breed in the Northern Hemisphere, with about 30 species ranging from temperate zones to the Arctic. Species that nest inland often come to the coast in winter. Adult birds are mostly gray or white with various spots on their heads. During the breeding season, the head may be pure white, or entirely black, entirely gray or entirely brown; in winter, stripes or unclear spots appear on the head. The beak is hard and slightly hook-shaped, and some species also have a color spot. The color of the beak and legs and the shape of the wings are the basis for classification. Gulls feed on seaside insects, molluscs, crustaceans, and worms and grubs in cultivated fields. They also prey on small fish on the shore and pick up leftovers discarded on the shore and on boats. Some large gulls prey on the eggs and chicks of other birds (including their own species).

It is generally believed that gulls can be divided into several genera, but many scholars regard them as one large genus: Larus. The black-headed gull (L. ridibundus) has a dark head and dark red legs. It breeds in Eurasia and Iceland and winters south to India and the Philippines. It usually forages in the fields and its main food is insects. The North American little black-headed gull (L. philadelphia, Bonaparte's gull) has a black head and bill, gray feathers, and pink to red legs. They nest in trees and prey on insects in ponds; they can still jump into the sea to catch fish in winter. The California gull (L. californicus) in North America breeds inland and spends the winter on the Pacific coast; it is said to have saved the crops of the early Mormon residents of Salt Lake City from being destroyed by the Mormon cricket (a long-horned locust). It became the state bird of Utah. Franklin's gull (L. pipixcan) breeds in large flocks in the swamps of the northern United States and overwinters on the Pacific coast of South America.

The Arctic Gull (L. hyperboreus) in the northern ocean has mostly white body, pale pink feet, and a yellow beak with a red spot; sometimes it winters south to Hawaii and the Mediterranean. The Great Black-backed Gull (L. marinus), with a wingspan of 1.6 meters (63 inches), is the largest gull; it is almost circumpolar, but is not found between Labrador and Japan. The herring gull (L. argentatus) is distributed in the northern hemisphere and is the most common Atlantic gull. It has a gray body, flesh-colored legs and feet, and black and white spots on the tips of its wings. It is scavenger and feeds on garbage and filth in coastal waters. The Black-backed Gull (L. dominicanus) is widely distributed in the Southern Hemisphere (including Antarctica) and has a black back. The Laughing Gull (L. atricilla) is medium-sized, with a black head, red beak and feet. It often emits a harsh, laughing sound. It breeds from Maine to northern South America and winters south to Brazil. Although it is a coastal species, Often deep inland in freshwater areas; the Laughing Gull is the only gull that breeds in both the Caribbean and the North Atlantic. The little gull (L. minutus) is distributed in Europe and occasionally seen in North America. It has a black head and a wingspan of about 60 cm (24 inches). It is the smallest gull.

The Pacific Gull (L. pacificus) breeds in Tasmania and southern Australia. The ring-billed gull (L. delawensis) is a common species in inland lakes in North America and often gathers in large flocks to forage on cultivated land. The gray gull (L. hemprichi) in the western Indian Ocean has a dark brown head and a light gray-brown head. Rhodostethia rosea is white and slightly pink, beautiful and elegant. It breeds in northern Siberia and can range as far as the Arctic Ocean. Sabine's gull (Xema sabini) is very abundant in the Arctic. It has a forked tail and runs and pecks like a snipe. The Swallow-tailed Gull (Creagrus furcatus) is found in the Galapagos Islands and is the only gull with a deeply forked tail. The scientific name of seagull in the narrow sense: Larus canus

Harbor Cleaner—Seagulls Seagulls are the most common seabirds. Even when people mention seabirds, they will naturally think of seagulls first.

At the seaside, in the harbor, and on the fishing grounds rich in fish and shrimp, flocks of seagulls are jumping for joy. Some of them are floating leisurely on the water, some are swimming and looking for food, some are flying at low altitude, and some...occasionally see two Suddenly, like an arrow from the string, seagulls shot straight into the sea, then immediately took off again, fighting each other for a fish. Generally speaking, where there are seagulls, there will be fish, and where the boats cast their nets for fishing, there will be seagulls.

Li Bai, the great poet of the Tang Dynasty, said in a poem: "All birds gather in Rongke". Of course, seagulls also like to gather in sea areas where food is abundant. Therefore, wherever large flocks of seagulls are found, the waters must be teeming with life. Fish leap in the blue sea, and gulls fly in the blue sky, making the rich ocean full of vitality.

In addition to eating fish, shrimp, crabs, and shells, seagulls also like to pick up leftovers discarded by people on ships, so seagulls are also nicknamed "harbour cleaners". They are almost a common sight around ports, docks, bays and ships. There will also be seagulls following the ship's route. Even walking on the beach at low tide will startle a group of seagulls.

In summer, seagulls fly to their breeding grounds. They build nests with dead grass, branches, feathers, seaweed, etc. shaped nest. In some places, the density of bird nests is very high, with two nests being 1 to 2 meters apart. Each parent bird has designated its own "sphere of influence" and does not allow other birds to invade, so it is inevitable that "neighbors" will often quarrel.

Seagulls have a strong ability to return home, and both males and females can return to the nests they built the previous year. Each nest lays 2-4 eggs, and both parents incubate the eggs. The chicks hatch in about 25 days. After 40 days, the chicks fly to the sea and begin to live independently.
