In alternate plumage, the reddish face and breast can also be found in the Curlew Sandpiper and Sanderling. The Curlew Sandpiper has a decurved bill and a white rump while the smaller Sanderling has black spotting on the breast and a bold white wing stripe. In basic and juvenile plumage, it is considerably larger than 'peeps' (Least, Semipalmated, Western, et al). Stilt and Curlew Sandpipers are similar in size but have decurved bills. Yellowlegs are larger with thinner bills and bright yellow legs. In flight, the featureless gray rump, back, tail and plain wings are different from other shorebirds that have white or black rumps and wing stripes.
