Well, I have had a few replies, and the most common suggestion is that it is a first-year Herring Gull. It does look very much like one of the photos on allaboutbirds.org, so I have no reason to doubt that this is a pretty solid ID. I don't remember where I saw it, but I completely agree with the simplified Gull ID methodology that someone posted in a blog somewhere: "There are only two kinds of gulls, white guls and grey gulls." I guess this one is a grey gull ...
