Yellow-legged Gull michahellis 3CY, December 14 2003, Westkapelle, the Netherlands (51.33N, 03.25E).

A more or less ordinary 3CY Yellow-legged Gull, with P10 fully grown, the primary moult score is 50. Note the immature broad dark bill-band and the red spot, almost completely obscured by the black. The black bill-band runs back to the base along the culmen. The complete moult in the upper-parts and head-feathers have been finished by late September, leaving birds with typical streaked heads on crown, nape and ear-coverts.
It has relatively small tips on the outer primaries P7-P10 and small tips on the tertials. There is some immature barring in the wing-coverts: barring on the central greater coverts and lower tertials. The legs are pale pinkish-yellow.
