Larus armenicus 4cy, 18 March 2011, Maagan Michael, Israel. Picture: Amir Ben Dov.
Bird aged by 3rd gen-like inner primaries and adult-like grey inner greater primary coverts, in combination with very adult-like secondaries and almost completely white tail. Bill typical for this age-class as well. No mirror on P10 in this bird may however suggest 3rd CY.
