Yellow-legged Gull michahellis 2CY, October 22 2001, Westkapelle, the Netherlands. 

This individual shows the average moult timing in 2CY michahellis by the end of October. After the complete moult in summer, a partial moult was started from late August onwards. Most obvious replacements took place in the upper tertials and inner wing-coverts. Recently moulted feathers show a greyish-brown base and fringe combined with ill-defined dark brown patterns. Note the rather dense variegated barring on the old outer greater coverts and the delicate head streaking on this individual.
