Larus armenicus sub-adult, 18 August 2010, Maagan Michael, Israel. Picture: Amir Ben Dov.
Sub-adult in active complete moult. Aged by black markings in the secondaries and in the outer rectrices. bLack of mirror in P10 might even make this bird a 3cy, but overall adult-like plumage probably advocates 4cy.
P4 fully grown and with sub-terminal black markings on both webs, P5 at 3/4 of the final length, P6 missing, P7-P10 still old (score P4/P7).
