"The general color of the upper surface in this species is a dark umber- 

 brown ; but the base of the feathers of the creast is white and the margins 

 of the other occipital feathers are of a light yellowish brown. Some of 

 the scapulars and other alar feathers (especially the latter) are slightly 

 tipped with the same ; the tail, which is of a somewhat lighter brown than 

 the back, is tipped with a very narrow edging of white, and is also crossed by 

 seven blackish brown bars, the upper one, however, being somewhat in- 

 distinct, and the two lower being separated by an interval which is twice 

 the breadth of the spaces between the other bars. The throat has a broad 

 blackish band running down the center, with two similar and nearly 

 parallel bands proceeding from the corners of the mouth, the three bands 

 all merging in a cluster of dark brown laceolate marks upon the upper 

 portion of the breast, the intervals between these markings, and also the 

 whole sternal and abdominal regions, being tinged with a yellowish 

 rufous; the under tail-coverts are barred with brown and white, the 

 former bars being much broader than the latter ; and the thighs and tarsi 

 are marked throughout their length with narrow, equidistant, transverse 

 bars of the same color. Length, 635 ; crest, 63 ; wing, 375 ; tail, 292 ; 

 tarsus, 89 ; middle toe with claw, 76." (Sharpe.)
