Appearance:

Large, stocky Calidris. Easily identified when direct size-comparison with congeners possible. Elongated body shape and short legs. Bill robust, short and straight. Summer plumage: Upperparts speckled in brown and grey, underparts warm rufous brown, like Curlew Sandpiper. Legs dark. Winter- and juvenile plumage: Pale grey upperparts (scaly pattern in juveniles), and white belly. Legs greenish in both juveniles and winter-plumaged adults. Note pale grey rump and uniformly grey tail in flight. Wing-bars less prominent than in Sanderling.
