It was a great trip for Gulls, in addition to Saunder's, Black-headed and the ever-present Black-tailed, we also had good looks at Vega, Mongolian, Heuglini, and Slaty-backed. Slaty-backed is the only one I wasn't able to photograph.

The harbor area of Eocheong, where this bird was photographed, was the only location we had Vega's. Mongolian was pretty wide-spread, and never showed the extensive nape-streaking shown by this Vega.
