Description

The Ring-billed Gull is a medium-sized gull known for the clear black band around its yellow bill, which can be seen in adults. During the breeding season, adults have a white head and underside, with pale grey back and wings. Their wing tips are black with white spots, and their legs are yellow. In winter, adults develop light brown streaks on their heads. Young birds have mottled brown feathers and take three years to look like adults. This bird is native to North America, where it breeds in central and northern areas. In winter, it moves to the coast and inland waters. In Britain, it is a rare but increasingly common visitor, especially in southern England and Ireland during autumn and winter. The Ring-billed Gull is flexible in where it lives. It can be found near lakes, rivers, reservoirs, farmland, rubbish dumps, and car parks. It often stays near Common Gulls but can be told apart by being bigger, heavier, and having the distinctive ring on its bill.
