UPDATE ON THIS MYSTERY BIRD: got two interesting reponses…one saying it was a Buff-breasted Sandpiper, highly rare on Pacific Coast…the other that it was Red Knot, simply uncommon but regular around here. I agree that this bird is too high-hipped to be a comfortable Sanderling ID and today there were Sanderlings all over the place, shorter and dumpier.
Here is one more picture, reinforcing two arguments for this being the rarer B-Breasted: yellowish legs, slender body not the rotundity usually seen on Knots.
ANY FURTHER COMMENTS WELCOMED.

NOT A MYSTERY BIRD: The Semipalmated Plover has only half the number of neck stripes as its bigger cuz, the omnipresent Killdeer, but little SemiP is sure a charmer, cute and pert and running about watching the humans on the beach:
MYSTERY BIRD ID:
this is a breeding plumage Sanderling, not a bird many of us will ever see south of the Arctic. He and three dowitchers were mixed in with all those little peeps today. But at least this Sanderling ran toward me and posed for pictures. Those dowitchers may be in California by now as they were motoring south.
