A 1cy Yellow-legged Gull which clearly shows the tail pattern. The tapered, wedge-shaped tail-band is slightly broader than usual but obviously finishes as a very small line in the outer-web of R6. The outer tail-feathers R6 have the black markings confined to the sub-terminal band, lacking loose black spots on the basal half. 
Note the differences in moult stage in the two wings, with two greater coverts replaced in the right wing.
