Sp. Ch. —Above and on the sides of the head, neck, and breast, grayish brown, darker on the crown ; region about the eye dusky. 
The chin, throat, and upper part of the breast, similar to the back, but rather lighter and tinged with the color of the rest of tho 
lower parts, which are pale cinnamon. Under wing coverts pale rusty white. The wings of a rather deeper tint than the back, 
with the exterior vanes and tips of the quills darker. Edges of the greater and secondary coverts, of the outer vane of the outer 
primary, and of the secondaries and tertials, dull white. The upper tail coverts and tail nearly black. Edge of outer vane of 
exterior tail feather white. Bill dark brown, rather paler beneath. The feet brown. Second, third, and fourth quills nearly 
equal ; fifth nearly equal to sixth ; sixth much shorter than the fifth. Tail broad, emarginate. Tarsi with a posterior row of 
scales. Length, 7 inches ; wing, 4.30 ; tail, 3.35. 
Hab. —Missouri and central high plains westward to the Pacific and south to Mexico. 
The young of the year have the upper parts slightly tinged with ferruginous ; two broad 
(ferruginous) bands on the wings formed by the tips of the first and second coverts. The quills 
and tail rather darker than in an adult specimen. 
The bill of this species is narrow, similar to that of S.fuscus. Legs and feet large, stout; a 
separate row of about eight or ten nearly rectangular scales behind the tarsus, most conspicuous 
in a young specimen. Wings long ; tail nearly square, very little emarginate; the feathers 
broad, the edges nearly parallel; the tip of the outer one obliquely truncated, with the angles 
rounded. 
A specimen from California (5510) otherwise similar, has the bill much smaller than the 
average, measuring but .43 of an inch from the nostrils, and .15 from the gape.
