Juvenile Baird's Sandpiper photographed by Curtis A. Marantz on 22 August 2020 at the back-basin ponds of Lake Elsinore, Riverside County, California.
観察結果の詳細
I saw six Baird's Sandpipers on one pass along the shoreline of the northern back-basin pond and one more at the southern back-basin pond; all were juveniles. Although these birds varied somewhat in their plumage patterns, all were somewhat larger than the Least and Western Sandpipers with which they were associated, and all had conspicuously long wings that resulted in an appearance that was both horizontal and with a finely tapered rear end. The best seen birds all had crisp scaling above that combined dark centers and buffy edges and in some cases whitish tips to the scapulars and coverts. All of these birds had a hooded appearance with the breast about the same color as the head and upperparts, but at least the closer birds also appeared to have white throats. I only once or twice did I heard one of these birds give the low, grating call that is typical of this species.
