A Glaucous-winged Gull gives me the eye. This large gull is the common coastal/urban species here, found year-round. It's a four-year white-headed gull, meaning it takes four years for a bird to attain its full adult plumage, which includes--uh--a white head. Similar species include Herring and Western Gulls, with which they interbreed.
This bird is an adult, but has a dingy head typical of nonbreeding months (September-March).
They eat almost anything. I recently saw one trying to down a sea star that was not cooperating. I don't know how the stand-off turned out.
When I was a teenager, my birding buddies and I would drive to Niagara Falls in winter to look for exotic gulls, including Glaucous-winged. A long move west, and exotica becomes dross.
