(Larus argentatus), a bird of the order Char-adriiformes. The body is about 60 cm long and weighs 0.8–1.5 kg. The herring gull is predominantly white, with a blue-gray back and black wing tips marked with white. The bill is yellow, and there is a red spot on the gonys. The herring gull inhabits northern and temperate latitudes of Europe, Asia, and North America. In the USSR the bird inhabits seas (except the seas of the Far East), large rivers, and lakes. The herring gull is a migratory bird in the north. It nests in colonies on the ground or on rocks. A clutch contains two or three eggs, which are incubated for 25 to 27 days. The herring gull feeds on aquatic invertebrates, fishes, rodents, carrion, and berries; in some places it does great harm by destroying the nests of other birds, for example, eiders.
