The Herring Gull, Larus argentatus, is a large gull and is the most abundant and best known of all gulls along the shores of Asia, western Europe, and North America. It breeds across North America, Europe and Asia. Some Herring Gulls, especially those resident in colder areas, migrate further south in winter, but many are permanent residents, e.g. those on the lower Great Lakes, on the east coast of North America or at the North Sea shores. Herring Gulls are also abundant around inland garbage dumps, and some have even adapted to life in inland cities
The male Herring Gull is 60-66 cm (24-26 in) long and weighs 1050-1250 grams (2.3-2.8 lb) while the female is 55-62 cm (22-24.5 in) and weighs 800-980 grams (1.8-2.2 lb). The wingspan is 137-150 cm (54-59 in). Adults in breeding plumage have a grey back and upperwings and white head and underparts. The wingtips are black with white spots known as “mirrors” . The bill is yellow with a red spot and there is a ring of bare yellow skin around the pale eye. The legs are normally pink at all ages but can be yellowish, particularly in the Baltic population which was formerly regarded as a separate subspecies “L. a. omissus”. Non-breeding adults have brown streaks on the head and neck. Male and female plumage is identical at all stages of development, however adult males are often larger.
Juvenile and first-winter birds are mainly brown with darker streaks and have a dark bill and eyes. Second-winter birds have a whiter head and underparts with less streaking and the back is grey. Third-winter individuals are similar to adults but retain some of the features of immature birds such as brown feathers in the wings and dark markings on the bill. The Herring Gull attains adult plumage and reaches sexual maturity at an average age of four years.
