Yellow-legged Gull michahellis 3CY, October 14 2001, Westkapelle, the Netherlands(51.33N,03.25E).

A more or less ordinary 3CY Yellow-legged Gull, with P10 almost fully grown. Note the immature broad dark bill-band and the red spot, almost completely obscured by the black. The complete moult in the upper-parts and head-feathers have been finished, leaving birds with typical streaked heads on crown, nape and ear-coverts. Here, the black streakings runs down along the sides of the breast.
It has relatively small tips on the outer primaries P7-P10 and immature barring in the wing-coverts: barring on the central tertials,  brown feathers in the outer lesser coverts (the carpal edge), the outer median coverts and central greater coverts. The tail shows black markings in the otherwise recently moulted rectrices.
