Interior and coasts of North America from the Saskatchewan and Labrador to Great Salt Lake (breeding), and in winter to the middle and southern States, Cuba, and the Bermudas. An immature bird in my collection obtained by Mr. H. Whitely at Hakodadi, Japan, 14th December, 1864, seems from its size and stout barred bill to belong to this species. The adult is easily distinguished from L. canus by its larger size, stout, double-zoned bill, and lighter mantle; it is smaller than L. californicus, its wing-pattern is different, and the mantle is much lighter. 14.
