Larus fuscus fuscus sub-adult, September 13 2013, Ashdod, Israel. Picture Amir Ben Dov.
Probably sub-adult fuscus, showing only very small mirror on P10. Some true adults may have small mirrors, but as small as these P10 mirrors? Probably best aged sub-adult, although not many other clues for immaturity.
With heuglini in background.
