Calidris alba
An energetic, stocky and robust wader. Black legs and bill. Black wing-bend (not always visible), and broad white wing-bars framed in black. Summer plumage with rufous head and back. Winter and juvenile plumaged birds gives a much whiter impression than all congeners, with light grey upperparts and pure white underside. Juveniles with star-shaped, black markings on back. Lacks hind toe.
Call not very diagnostic; a short and soft "pleet" or "keek".
