This is one of 3 crisp juvie Sanderlings (with a Pectoral here) seen today on the flats at the mouth of the Big Sandy River in Henry Co. TN.

I think juvenile Sanderlings are among the most striking of shorebirds,with their clean white with black spangled plumage. Notice the lack of a hind toe, an adaptation for running, peculiar to Sanderling among the Calidrids.
