Larus armenicus 2cy, 15 December 2010, Maagan Michael, Israel. Picture: Amir Ben Dov.
Upper tertilas, inner gc and most of the visible mc replaced in the partial autumn moult, now more adult-like than the adjacent feathers, often grey-based with an ill-defined black shaft streak. Note the contrast with the typical 2nd gen-like pattern in the llc.
