The black pattern in the outer primaries is diagnostic for second winter (3cy by January) Mediterranean Gull. This individual is metal ringed: Budapest 368817. From May to September, a complete moult takes place, into so-called "second winter" plumage. The head pattern resembles the pattern in first winter birds, with blackish mask behind the eye from September onwards. In some birds the mask is confined to a sole black spot on the rear ear-coverts. The mantle, scapulars, tertials and all the wing-coverts are replaced for plain pearl-grey feathers. The secondaries are completely white. The second generation primaries are pale pearly-grey, especially the inner primaries. In this 3cy Mediterranean Gull, the wing-tip pattern is diagnostic with black on P5-P10: P5 has only a small black sub-terminal spot, becoming gradually larger on the outer primaries as the black patch "eats up" along the edge of the outer-web, most prominent on P10, although P10 lacks the sub-terminal band. In some birds, the outer greater primary coverts may show dark markings as well. The bill is orangey-red with a dark sub-terminal band. The legs are dull red or more obvious orangey-red.
