Just saw this on the NARBA site. Just wondering why no one has
reported it to CalBirds? See below......
California: On December 2nd, an adult SLATY-BACKED GULL was seen on
the beach directly across from the lagoon at Frenchman's Creek at
Venice Beach. The Slaty-backed Gull should be looked for early in the
morning on the beach after it flies in from the ocean, where it has
roosted during the night or after its return flight in the afternoon
if it has visited the dump.
Venice Beach is located in Half Moon Bay State Beach and is at the end
of Venice Boulevard off Highway 1.
