I spotted this beast yesterday. Its plumage is OK for a Caspian Gull, but structurally it seems to be a bit mixed up. Its short legs, chunky body and largish head hint at Herring Gull, but equally there is a bit of Caspian Gull about it too.
It is a second calendar-year, first-winter/summer. At this age Herring Gulls haven't replaced their coverts, but this chap has, which is a feature of Caspian Gull, as is the white head and the silvery grey scapulars.
For me this is quite an obvious hybrid.
