Larus armenicus sub-adult, 09 February 2011, Maagan Michael, Israel. Picture: Amir Ben Dov.
Black on P3-P10. Obvious mirror on P10. Secondaries without dark markings in centres, but adult-like. No black in tail-feathers. Adult-like pattern of central primaries, with medial black band in P6 and P7 sharply demarcated, not gradual. Several primary coverts with limited black markings. Probably in 5cy, but extent of remaing immature features still not fully understood in armenicus.
