Typically Western is one of the brighter peeps. This one is a faded adult that's moulted its scapulars to winter gray but retains faded wings and a few black flecks along the flanks retained from breeding plumage.
Dunlin would also lack the semi-palmations, would be a larger bird with an even heavier bill. With the wings fully flared you can see a little rufous in the central scapulars even in the presumed winter plumage.
The bird mainly hung out with a flock of sanderlings that was moving back and forth between the beach and the piers.
This pic again ties my personal best 4 species in one frame at Tiscornia. I think the last time I did it was with essentially the same species, just semi instead of Western
I'm now safely back on my couch where I should be able to stay for back to back football triple headers ... unless of course there's something requiring my attention at the pier. Thanks to Tim for schlepping my scope (stupid 10 pound weight restriction). I was probably looking pretty pitiful shuffling along.
