About the Lesser Black-backed Gull
I see that Charlie and Sam saw it on top of a building which is where I had it earlier and called to Tom Benson to report I just had it. Anyhow, this is starting to look like it may be a spot it goes to. The first tall building, maybe 6 to 8 stories high, south of the Hotel Del, is where I had it and where I think Charlie had it as well. If you don't see it on the beach or on the Jetty, take a look up high.
