观察细节
Upon viewing the photos, Lucas DeCicco noted the *very* short primary projection of the individual I had photographed and identified as an American Golden-Plover by default. Structurally the legs did not strike me as being longer than what I'm used to for AMGP, though there were no other obvious Americans present to compare to. It would appear that the shortness of the primaries can rule out AMGP. It is also worth noting that the vent is predominantly whitish, and the whitish border appears to extend down the flanks rather than terminating near the mid breast. While the bird is still in molt, it also appears that there is no obvious bulging on the white border. It appears the right side of the bird's breast is more fully molted than the left and it seems there is no bulge to the white border. There is a fair bit of goldish wash to the otherwise white forehead, and while I have observed a similar wash in obvious AMGP, none (as of yet) have been this saturated a shade of goldish-buff. The bill also does seem to be longer than that of a typical AMGP. The fact that this bird is still in molt seems to complicate the ID a bit, I am open to other opinions. I unfortunately did not hear the bird vocalize and did not see the underwings, so theoretically cannot definitively rule out European aside for overall jizz. Apparent plain tertial "window" seems to also suggest Pacific rather than American or European. There are a fair number of eBird reports for this species from Barrow, obviously not all include notes, but considering the complexity of this ID, it may occur more regularly and is overlooked.
