L. a. argenteus, sometimes known as the British Herring Gull breeds in Western Europe in Iceland, the Faroes, Britain, Ireland, France, Belgium, the Netherlands and Germany. Many birds are resident while others make short-distance migratory journeys. It is smaller than L. a. argentatus with more black and less white in the wingtips and paler upperparts. The male European Herring Gull is 60–67 cm long and weighs 1,050–1,525 g while the female is 55–62 cm and weighs 710–1,100 g. 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. 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.
