Larus armenicus adult, 27 August 2010, Beit Shean, Israel. Picture: Amir Ben Dov.
Adult in active complete moult. Large moult gap (many primaries moulting simultaneously) in the left wing, but note that in the right wing thgis moult gap is much smaller, as P2 and P3 are longer. Score: P1/P7 for the left wing; P3/P7 for the right wing (which is an ordinary moult score). Left: P1 fully grown, P2-P3 halfway, P4 at 1/3 of the final length, P5-P6 missing, P7-P10 still old. Only one mirror on P10. Eight primaries with black.
