Life history of 3CV5.
From late summer to September, a complete moult took place, bringing adult Mediterranean Gulls into so-called "adult winter" plumage. The head pattern in wintering bird resembles "first winter plumage" after finishing the complete moult: a blackish mask behind the eye. The next moult in Mediterranean Gull is a partial moult, from January to April, and includes body and head, leaving birds in so-called "adult summer" plumage from early April onwards. However, some birds may develop a black hood from late February onwards. The head shows a jet-black hood, slightly extending down the nape. Adult birds have broad white crescents above and below the eye.
