Range. - North America, breeding from northern United States north to the Arctic regions; most abundant in the interior and the west; rare in New England.
This bird is shy and retiring and skulks off through the underbrush of thickets and swamps that it frequents upon the approach of anyone; consequently it is often little known in localities where it is quite abundant. They nest on the ground like Song Sparrows, and rarely in bushes. Their eggs are very similar to those of the Song Sparrow, three or four in number, greenish white in color, heavily spotted and blotched with chestnut and gray. Size .80 x .58.
Range. - Pacific coast of Oregon and British Columbia.
Similar to the preceding but darker and browner. Eggs probably like those of the last.
