Yellow-legged Gull michahellis 3CY, March 17 2003, Etaples, France (50.42N,1.34E).

Classic 3CY michahellis, showing plain grey scapulars and a mix of grey median coverts and older barred lesser and greater coverts. The colour of the bare parts was still immature one month ago, but by mid-March the base of the bill and the legs turn already slightly yellow. After the partial moult is finished by late-April, the legs will appear deep yellow and the head-streaking will disappear, leaving birds with clean white head and under-parts.
