Mediterranean Gulls started arriving on the coast at the end of June with up to four adults and one or two juveniles throughout July. The adults begin a post breeding moult in June and it's usually completed by October. The head moults from July with forehead, lores and chin, and more than 90% have a winter head by late August. The remiges - flight feathers (primaries and secondaries) start with the primaries P5 - 7 in August with P9 - 10 usually complete by mid September. The tail (rectrices) undergoes replacement between August and September. Eds.
