Range. - Western United States, breeding from Arizona, New Mexico and southern California north to British Columbia.
This unique species is of a uniform brownish gray color, with a white eye ring, narrow bar on wing, and outer tail feathers, and with the bases of the primaries rusty colored. It is a ground inhabiting bird, feeding upon insects and berries in shrubbery and thickets. Their song is said to be liquid, melodious and often long continued, equalling that of any other bird. They nest on the ground in hollows under banks or crevices about roots of trees or fallen stumps, making a large, loosely constructed pile of weeds and trash, hollowed and lined with rootlets. The three or four eggs, which are laid in June, are grayish white, spotted with pale brown, chiefly or most abundantly about the large end. Size .96 x .70.
