Caspian Gull

I was unable to read the ring number on this bird. Although it has typical plumage, head and bill-shape, a small eye and the characteristic line from eye to eye across the rear crown, its wings look a little short and the legs look thicker than normal, so it may contain some Herring Gull genes.
