Their upper parts are brownish gray, darker on the wings; bill and feet dark; under parts white, with the middle of the belly and the under tail covers dusky. Length about 20 inches. Little is known concerning their nesting quarters, although they are said to breed in Greenland. From the fact of their early appearance off the New England coast it is probable that the greater part of them nest in the far south.
