I've just gone through the photos of the golden plovers I found at Floras Lake Friday night, and... it's still a puzzle to me. I'm including a link to my eBird checklist here where I have added photos and tried to be thorough with notes.
The basic rundown: the bird in question undoubtedly shows some white in the flanks, but it is minimal, especially compared with the 2 definite Pacifics that were there. An American in molt would show some white, but so would a Pacific, obviously. The undertail coverts are a different story. From profile, rear, and flight views, the Pacifics show extensive white under the tail, while the bird in question shows solidly black undertail coverts. From my reading in the Obrien/Crossley/Karlson shorebird bible, and some internet research, I can't find an instance in which a Pacific would have that black of an undertail. But I could be mistaken and would happily hear what others with experience with the species pair would have to say.
I'm not trying to make the bird in question into an American, I just feel like the evidence leans ever so slightly in that direction. It may have to be left as a "Lesser" (i.e. American/Pacific), but I'd love to nail it down one way or the other with some help.
