Yellow-legged Gull lusitanius 1cy September 06 2009, Xove / Burela, Galicia, Spain. Picture Gabriel Martin.
Flight shot to show the tail pattern. Tail-band not really wedge-shaped, as the sub-terminal band hardly narrows towards the outer feathers. Also note the dark markings on the outer-web of R6. Tail pattern seems to be quite variable in 1cy lusitanius.
