European Herring Gull look-alikes

Key differences

Lesser Black-backed Gulls have a darker grey (slate-grey to black) mantle, yellow legs (not pink), and a slightly more slender build. Their wingtips are also black with white mirrors, but the contrast with the darker mantle is less stark. Juveniles are also generally darker and more uniformly brown.

Key differences

The Great Black-backed Gull is significantly larger, with a very dark (almost black) mantle, a much heavier bill, and pink legs. Its wingtips are black with smaller white mirrors, and the overall impression is much more imposing.

Key differences

Yellow-legged Gulls have yellow legs (as the name suggests), a slightly darker grey mantle than European Herring Gulls, and a more angular head shape. Their red orbital ring is often more prominent, and the red spot on the bill can be more extensive. Historically considered a subspecies of Herring Gull, now widely recognized as a distinct species.

Key differences

Often considered a separate species from the European Herring Gull, though some taxonomists still group them. American Herring Gulls typically have a slightly darker grey mantle, a more extensive red orbital ring, and often a more pronounced 'puffy' head shape in winter. Identification can be very challenging where ranges overlap or vagrants occur.
