 lighter (the scapulars, smaller wdng-coverts, and rump rather light sepia

Young male. — Very dift'erent from adults of either sex. General 

 color of upper parts sooty black, the pileum, hindneck, back, scapu- 

 lars, and smaller wing-coverts sharply and conspicuously streaked 

 with buft'y,'' the streaks broadest on back and scapulars and lateral 

 portion of the ])ileum, those on the latter forming a rather conspic- 

 uous though broken superciliarj^ stripe; rump and shorter (central) 

 upper tail-coverts streaked (usually broadly) with cinnamon-rufous; 

 longer and lateral u})per tail-coverts white, more or less tinged with 

 buff, their inner webs partly blackish; greater wing-coverts tipj^ed 

 with a large wedge-shaped spot of buft' or ochraceous-buff, their outer 

 webs narrowly edged with paler buff; remiges and rectrices as in the 

 adult female, but the large whitish spots at tips of innermost seconda- 

 ries tinged with buff, and white tips to rectrices less sharply defined; 

 a broad blackish postocular stripe; lower portion of auricular region, 

 suborbital and malar regions, and under parts buft', becoming whitish 

 on center of abdomen, the feathers margined with black or dark sooty, 

 these blackish margins broadest on chest, where they ])roduce a con- 

 spicuously sc[uamate effect. 



Young female. — Similar to the young male, but streaks on pileum, 

 back, etc., broader, more whitish, the general color above more sooty 

 brown; cinnamon-rufous streaks on rump and middle upper tail- 

 coverts narrower; otherwise, scarcely if at all dift"erent.
