Young specimens of gull argentea. The European herring gull (Larus argentatus) is a large gull. European herring gulls have a varied diet, including fish, crustaceans and dead animals as well as some plants. Juvenile and first-winter birds are mainly brown with darker streaks and have a dark bill and eyes. Second-winter birds have a whiter head and underparts with less streaking and the back is grey. Third-winter individuals are similar to adults but retain some of the features of immature birds such as brown feathers in the wings and dark markings on the bill.
