Larus armenicus 2cy, 02 October 2009, Ashdod, Israel. Picture: Amir Ben Dov.
Complete moult finished (P10 fully grown). A subsequent moult is quite common in 2cy birds, and in this bird as well. Note the missing upper tertial, inner greater coverts, outer median and outer lower lesser coverts. The new feathers often appear more adult-like, grey, albeit sometimes with ill-defined patterning ("spaghetti pattern").
