Distinguishing features

Adults have dark legs and a short, thin, dark bill, thinner at the tip. The body is brown on top and white underneath. They are reddish-brown on the crown. This bird can be difficult to distinguish from other similar tiny shorebirds. This is particularly the case in winter plumage, when plumage is plain gray. (Wikipedia)
