About These Birds
Ring-billed Gull
Ring-billed Gull, 43–54 cm, is North America's most abundant gull, breeding on lakes from the Great Plains to the Great Lakes and wintering on all coasts. Adult has a distinctive black ring near bill tip, yellow legs. Omnivore; thrives on garbage, parking lots, and agricultural fields.
Mediterranean Gull
Mediterranean Gull, 36–38 cm, has expanded dramatically since the 1970s, breeding across Europe from the Black Sea to Britain. Pure white body, jet-black hood in breeding plumage — the only gull with entirely white wingtips. Piscivore and invertivore; nests in colonies, often with Black-headed Gulls.
