Young, Above chocolate-brcwn, black on the head and intersca- 

 pular region, which are both streaked with ochraceous buff, forming 

 an eyebrow ; the wing-coverts irregularly marked with rufous, 

 especially on the greater series ; primaries black ; secondaries brown, 

 like the back, all barred with blackish, more plainly on inner web, 

 which is buff in the primaries, rufous in the secondaries ; upper tail- 

 coverts black, washed with rufous, and barred with white or bufiy

 subterminal one broader and more brown in colour ; sides of face 

 and of neck ochraceous buff, strongly streaked with black ; the upper 

 margin of ear-coverts and cheeks entirely black; lores buff; under

 on throat and largely on sides of breast and flanks, the latter being 

 almost uniform brownish black ; thighs, abdomen, and under taU- 

 coverts barred across with black, less numerously on the latter ; under 

 wing-coverts ochraceous buff, with large heart-shaped spots of black.

Adult male. Entirely black ; nape slightly varied with buff-
