There was a breeding-plumaged Red-necked Grebe with a couple dozen Western and Clark's Grebes off of Pt Dume around noon today. I was on a boat, but close to shore, and this bird should be scope-able from the beach near off the west side of the point.
Other things on the water between Pt Dume and Marina Del Rey included nearly a hundred each Casssin's and Rhinoceros Auklets, a few Scripps's Murrelets, and a handful of Red Phalaropes.
