Larus armenicus sub-adult, 09 February 2011, Maagan Michael, Israel. Picture: Amir Ben Dov.
Obvious mirror on P10. Secondaries without dark markings in centres, but adult-like (except S1). No black in tail-feathers. Adult-like pattern of central primaries, although medial black band in P6 and P7 not sharply demarcated, rather gradual. Several primary coverts with limited black markings. Probably in 5cy, but extent of remaing immature features still not fully understood in armenicus.
