Hab. Central region of North America, from boundary of United States

There is a very great difference in the length of the bill in different 
specimens of this species. The longest (20,871) measures .75 from 
nostril, and 1.15 from gape; while in another the bill is .15 shorter. 
I have not seen specimens of this bird from any point west of 
Fort Tejon, although it is said to occur in the Sacramento Valley.

Bill short, conical, high at base, not notched at tip. Culmen much curved. 
Nostrils in anterior extremity of nasal groove; broadly open and oval, but 
with a narrow membrane above. Internal lateral septum apparently revolute, 
so as to be perpendicular to the central septum, its exposed edge crossing 
the nasal aperture obliquely forwards. Legs very stout; hind toe and claw 
nearly as long as the middle, which are much shorter than tarsus. Wings 
about equal to the much graduated tail. Plumage Wren-like ; uniform brown, 
with dusky lines on wings and tail.
