The Mysterious Bird

That bird I don't recognize is still hanging around, though not close enough to get any good pictures. It seems to be some sort of diving waterfowl, like a duck but with the wrong kind of bill for a duck.

In other on-the-rocks news, a laughing gull was yelling its head off at another laughing gull standing next to it, and was a real pest about it, until the other one finally regurgitated a fish and handed it over. Since they both had breeding plumage, I'd guess they were mates rather than parent/kid.
