Larus armenicus sub-adult, 18 March 2011, Maagan Michael, Israel. Picture: Amir Ben Dov.
Probably 4cy bird. Immature looking individual, lacking mirror on P10. Adult-like inner primaries and white tips also on outer primaries (therefore probably not 2nd gen primaries, hence no 3cy bird). Still many immature features, like black in tail and on greater primary coverts. Some secondary centres adult-like grey, but most outer feathers with dark centres (so probably not 5cy bird).
