Larus armenicus sub-adult, 15 November 2010, Maagan Michael, Israel. Picture: Amir Ben Dov.
Sub-adult armenicus with P8 fully grown, P10 already visible. Now the old primaries are not present anymore, exact ageing difficult. Some black in the primary coverts, dark centres on the secondaries and dark patches in the lc point to sub-adultness. Complete white tail and large mirror on P10 probably should advocate 4cy plumage.
