    That bill is awfully thin and decurved for a Willet and the structure is way off. It looks like a leucistic Stilt Sandpiper.

    I see what you're saying with Stilt but I'm not sure that's right. Barring on the sides and structure do look Stilt Sand like.

    If this is a Willet, it's a Western Willet, which have thinner bills than Eastern. The white in the wing here could be leucism, but something other than that just doesn't look right for Stilt to me. Bird seems really chunky for a species that shouldn't be much larger than a Dunlin. Bill also looks rather straight for Stilt I would think. 

    Not sure either way, but just some thoughts.

    I don't think that feature applies to nonbreeding adults. I based my ID on the barred underwing lesser coverts, but I could be wrong.

    @akiley could give you a more definite answer.

    Any feature involving orange/red color definitely isn't relevant for basic plumaged birds. I would agree with SB for the reasons you mentioned on the open wing and also, these birds seems fairly slim in shape. I don't get a LB impression from either bird.

    Why "American," when there are multiple names subspecies in the Americas? I don't want to get into the acceptability of Tule Goose as a subspecies, but since it's named....

    From the BNA account:

    "

    Subspecies

    Only 2 subspecies breeding in North America are recognized by American Ornithologists' Union (American Ornithologists' Union 1957😞 A. a. frontalis breeds from w. and nw. Alaska across n. Canada; larger, darker A. a. gambeli (Tule Goose) restricted to vicinity of Cook Inlet, AK. Latter has been referred to as A. a. elgasi (Delacour and Ripley 1975); scientific name remains in contention (R. Banks pers. comm.). A. a. flavirostris slightly larger and darker than A. a. frontalis; A. a. albifrons is similar in appearance to A. a. frontalis, but smaller (Cramp and Simmons 1977). Breeding-ground limits of A. a. albifrons and A. a. frontalis in ne. Asia (Kolyma River Highlands) poorly documented. No Nearctic band recoveries in Siberia, or Palearctic recoveries in North America.

    Nomenclatural history reviewed by Banks (Banks 1983a). Much confusion; current range of subspecies incongruent with origin of type specimens. We use A. a. frontalis for smaller form and A. a. gambeli (spelling following recommendation of R. Banks) for larger form (American Ornithologists' Union 1957).

    I was using "American" to refer to the North America breeding forms, specifically gambelli/frontalis in comparison to Greenland. gambelli/frontalis may be a better way to word the question. What I'm asking is are they Greenland (flav) or not?

    None of them look like typical Greenlands to me.

    I just have to say, that's one of the most concise yet thorough descriptions of the differences of those two ssp. that I've ever seen. I looked at the entire flock and none of the birds appear to have bright orange bills and largely dark brown bodies. If you train your eye to look at all of those marks at once, typical Greenlands are surprisingly distinctive.

    Thanks so much! American is the opinion of almost everyone I have asked.
