Larus michahellis 4CY, January 26 2011, Istanbul, Turkey. Picture: Volkan Donbaloğlu.

Birds of this age are variable.This one has an obvious mirror in P10 but on others it is much smaller or even lacking. It has a clean white tail but many retain vestigial dark marks. The extensive blackish-brown primary coverts contrast with the otherwise grey upperwing. The black of the primaries forms a solid wedge on the outer wing in michahellis.
