Yellow-legged Gull michahellis 2CY, July 30 2001, Boulogne-sur-Mer, NW France.

Primary score: p7 is full-grown and there are no old juvenile primaries left. Moult is going on in the scapulars and lesser coverts. Note the pink legs and the the much more immature first impression compared to later pictures on the July Section, with e.g. picture 5627 showing a very advanced 2CY, resembling a 3CY michahellis. In 2CY michahellis, variation in scapular pattern is large, extending from heavily barred to adult-like grey. 

In this 2CY plumage, YLG michahellis and LBBG graellsii may be most difficult to separate.
