Yellow-legged Gull michahellis 2CY, April 19 2002, Etaples, NW France (50.42N,1.34E).

Compare 2CY michahellis with the 2CY argenteus in the background. The greater coverts are much darker in michahellis, the bold pattern on the rear lower scapulars are obvious and michahellis often shows third generation grey adult-like upper lower scapulars. Note the neck-collar as well, running down along the side-breast. This individual has all the tertials juvenile and at least two lesser coverts were replaced in the post-juvenile moult.
