Sorry Lou, but I have to disagree with your analysis🙂.
The bird in question is a first-winter Little Gull, in my opinion. Most of the images give a decent hint of an underwing pattern that is much more compatible with Little Gull than with Kittiwake, the impression being that there is a narrow white trailing edge to the wing, from the mid-primaries to the body, and even a faint suggestion of a secondary-bar. A Kittiwake would show considerably more translucency on the inner primaries and secondaries than we can see here. The very small bill and pinkish tinge to the body are further clues that point to Little Gull.
