From the second year through adult plumage, the Lesser Black-backed Gull has a very dark gray back. Great Black-backed Gull has wingtips the same color as the mantle, not darker as the Lesser, and pink legs. Western and Slaty-backed Gulls are larger and have pink legs. Yellow-footed Gull is larger with a darker back, larger bill, and a restricted range. First-year Lesser Black-backed Gulls are very similar to Herring Gulls but have whiter rumps, darker wing coverts, entirely black bills through their first summer, and paler heads and underparts that are spotted with brown. First-year Great Black-backed Gulls have whiter heads and are larger with much bigger bills, and have more strongly checkered wing coverts and secondaries.
