I first suspected this bird to be a young Great Black-backed Gull from what I felt was a rather large bill and dark eye. However, after reviewing images, it appears to be a 2nd- cycle American Herring Gull. The bill is large, but not bulky, and the gray back feathers suggest a 2nd-3rd cycle bird. However, the primaries are brown and white, and not black, tan and white as would be found in younger GBBG. Tail feathers appear to be all black. On a 3rd-cycle bird I would suspect some white to appear.
