Color. (Male cited above.) 



Head : With a rich rufous chestnut hood, extending from the bill back 

 above the eyes to the occiput ; each chestnut feather of this cap has a 

 central line or marking of dusky brown ; the rest of the head and sides of 

 the face pale grey brown, each feather decorated like those of the cap with 

 dark central markings, the whole having a finely striped or flecked 

 appearance. 



Neck : The throat whitish, with faint fine striping ; upper neck pale grey 

 brown, like the sides of the face and striped in the same way with dusky ; 

 the lower neck, both above and below, strongly rufescent, the feathers hav- 

 ing broad dusky centers, giving a spotted appearance. 



Back : Mantle, rump and upper tail-coverts dusky brown, each feather 

 margined with greyish brown, sometimes slightly rufescent. 



Tail : Greyish olive tinged with brown, each feather edged with rufous. 

 The feathers are long and acuminate, the two central ones are longest 

 and make a pointed tail. 



Wings : Scapulars dark dusky brown, strongly margined with reddish- 

 brown ; wing proper, grey brown ; the greater coverts the same shade but 

 tipped with buffish white for half an inch, thus forming the anterior 

 boundary of the velvety black speculum, which is sometimes glossed with 

 greenish ; this speculum is formed by the secondaries having a tipping oi 

 whitish buff three quarters of an inch wide ; inner tertials lengthened and 

 lanceolate and greyish brown in tone, with a broad velvety black central 

 stripe ; primaries greyish brown, darkest at the tips ; under wing-coverts 

 greyish brown ; axillaries greyish brown, with whitish brown tips. 



Lower parts : Feathers dull dusky brown in the center ; on the upper 

 breast these are margined with rufescent brown and this becomes whitish 

 on the lower breast and abdomen, and again greyish toward the vent ; 

 the feathers of the sides and flanks have decidedly rufescent edging and 

 this becomes cinnamon on the lower tail-coverts. 



Bill : Greenish black ; yellowish at the base and darkest on the culmen 

 and at the tip (Hatcher). 



Feet: Greenish lead-color (Hatcher). 



Iris: Hazel-brown (Hatcher).
