European Herring Gull (Larus argentatus) — identification, habitat & look-alikes

The European Herring Gull is a large gull that breeds mainly in northern and western Europe. Adults have a pale gray back, pink legs, and a yellow bill with a red spot. A similar-looking herring gull on a U.S. coast is usually an American Herring Gull (Larus smithsonianus).

Appearance

Appearance: Adults have white heads and underparts, pale gray backs, black wingtips with white spots, pink legs, and yellow bills with a red spot. Juveniles are mottled brown and take several years to acquire adult plumage.

Look-alikes

American Herring GullLarus smithsonianus

Adults look very similar, and many cannot be separated safely from a single photo. A clear view of the spread wingtips and the bird’s age can help; in the United States, American Herring Gull is far more likely.

Why they get mixed upThey were treated as one species until the recent split and share nearly the same size and color pattern.

Lesser Black-backed GullLarus fuscus

An adult Lesser Black-backed Gull (Larus fuscus) usually has a darker slate-gray back, yellow legs, and a slimmer, longer-winged shape. European Herring Gulls usually have a paler back and pink legs.

Why they get mixed upBoth are large European gulls with white heads, gray backs, and black wingtips, and both can occur in North American gull flocks.
