Larus armenicus 3cy, 15 December 2010, Maagan Michael, Israel. Picture: Amir Ben Dov.
3cy individual, with obvious mirror on P10. No black on inner primaries (adult-like P1-P2), white tail with very limited solid black markings. Broad black band on the bill.
This 3cy age-class may still show some black centres in the secondaries, and in almost all 3cy December birds, the greater primary coverts have extensive brownish centres. There may also be some pattern in the feathers of the carpal edge.
