I was on my return trip from the North Beach when several peeps flew by along with a larger bird. Unfortunately, I did not get a very good look at the larger bird. I turned around, but failed to find the mystery bird. Returning south after giving up, a larger shorebird was seen again. This time, I saw where it landed. As soon as I saw the bill, I knew that it was a plover. The brownish appearance and lack of black on the underside of the wing eliminated the possibility of a Black-Bellied Plover. I knew it had to be one of the Golden-Plover species. I originally listed this as a Pacific Golden-Plover. After communication with another birder, I have decided to revise this entry. Among field marks to justify calling this an American Golden-Plover are the head shape, tertials ending at the base of the tail (this looks like a good indicator that was conveniently missing from my field guides), and the four primary projections that seems to be the most commonly used field mark.
