Another very pale bird with a jizz similar to Caspian Gull. This individual has replaced many feathers on the wintering grounds, including all visible wing coverts, tertials, rectrices, plus several secondaries. The underwing is nearly completely white. A possible mix-up with any western taxon seems unlikely.
