Adult. Upper half of the head, back of the neck, rump, upper 

 tail-coverts, and tail brownish black, strongly glossed with green ; 

 wings bright chestnut, generally, but not always, jxissing into duller 

 and darker brown on the inner half of the wings and back, the 

 quills with broad dark ends ; beneath white tinged with buff, and 

 occasionally, though rarely, the sides of the body and the under tail- 

 coverts showing faint traces of darker bars : bill and legs black ; 

 iris red. Total length 16*5 inches, culmen 1-2, wing 6"6, tail 8*5, 

 tarsus 1-6. 



Immature. Only differs from the adult by having blackish bars on 

 the mantle and wings, and generally with traces of buff bars on the 

 upper tail-coverts and tail. In this plumage it may be distinguished 

 from C. natalensis by the entire absence of any buff shaft-stripes on 

 the upper parts.
