About These Birds
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.
Arctic Herring Gull
Arctic Herring Gull, 55–66 cm, breeds across Arctic North America and winters on all coasts of the US. Formerly lumped with European Herring Gull; darker-eyed on average, slightly more northerly range. Omnivore and scavenger; abundant at fishing ports, dumps, and beaches in winter.
