Range. - Western North America, breeding in the Arctic regions and migrating through the United States, chiefly west of the Mississippi to the Gulf States and southward.
Scarcely to be distinguished from the preceding species, but the upper parts are said to be brighter and the bill, to average a trifle longer. The nesting habits and eggs are precisely the same as those of the Semipalmated variety. Data. - Cape Prince of Wales, Alaska, June 28, 1898. Four eggs. Nest a neatly rounded hollow, sunk into a mossy hummock in marshy ground. Collector, Joseph Grin-nell.
