 the outer lateral toe a little the longer, and reaching a little beyond the base of the middle 

 claw. The hind claw about equal to its toe ; the two together about equal to the outer toe. 

 Claws all stout, compressed, and moderately curved; in some western specimens the 

 claws much larger. Wings reaching about to the end of the upper tail-coverts; short and 

 rounded, though the primaries are considerably longer than the nearly equal secondaries 

 and tertials; the outer four quills are graduated, the first considerably shorter than the 

 second, and about as long as the secondaries. Tail considerably longer than the wings, 

 moderately graduated externally; the feathers rather broad, most rounded off on the 

 inner webs at the end. The colors vary; the upper parts are generally uniform black or 

 brown, sometimes olive; the under white or brown; no central streaks on the feathers.
