I studied the continuing bird that was first found at this site by Guy McCaskie on 28 March relatively carefully in the field, but I also waited a week to write a description of this bird, so my recollection of it is a little fuzzy. Hopefully my photos will clarify some of the points that I could not remember. Much as I had been told was typical for this bird, it moved relatively rapidly by walking around the small tamarisk trees picking items from the surface of the vegetation. Given that it was closely associated with the plant is also moved back into the vegetation where it was hard to see (though it did come out in to the open on occasion). I only once saw this bird fly a short distance. This was a small Ruff in that it was no larger than the dowitchers with which it was associated, and in fact, I thought its body was slimmer than those of the dowitchers even though its neck seemed to be somewhat longer and slimmer. The bill was about one-and-a-half times as long as the head was wide, it was straight, and relatively slim throughout its length. The head was small and the neck was relatively long, but the forehead seemed steeper than those of the dowitchers and the crown maybe a little more rounded. The body was plump, full-chested, and with a somewhat hunch-backed appearance, but the wings were relatively long and tapered, with the wingtips apparently reaching right about to the tip of the tail. The legs appeared to be as long as those of the dowitchers, but they were more conspicuous given their bright coloration. This bird's upperparts were boldly marked as a result of the contrast between the darker centers and paler fringes of the feathers, yet it was not overly colorful. The head and neck were a medium grayish-brown color that was somewhat colder than the shade that characterized the dowitchers. I noticed a limited amount of white along the base of the bill but I am not sure if any of this white extended onto the forehead (though if it did it was quite limited). The muted pattern on the face pattern seemed to consist of a weak supercilium, apart from which the face was blank. The back and the larger feathers of the scapulars contrasted dusky centers with well-defined fringes of light brownish-gray that extended down both edges of each feather and across the tip to create a conspicuously scaled pattern. I thought the pattern was similar on the visible wing coverts, but the scaling was smaller as a result of the smaller size of these feathers. Even the tertials had a similar pattern, but as a result of their more elongate shape, the pattern appeared to be more of striping on the rear part of the wing. The longest tertials appeared to nearly reach the wingtip, so it was difficult to detect any pattern on the primaries. Unlike the dowitchers, this bird was quite pale below, with the lower part of the face and the throat, the breast, belly, flanks, and undertail coverts all essentially white and unmarked. I am now less sure about the pattern at the sides of the breast, however. I saw this bird only briefly in flight, when I thought the wings had at most a rather weak pattern, but I concentrated more on seeing the pattern on the rump, which was extensively white on the sides but with a narrow stripe of darker coloration down the center and more broadly on the tail. The bill appeared to be entirely black, the eyes were dark, and what I saw of the legs was a bright orange-yellow color that I likened to that of a pencil.
