the feathers being more or less distinctly, an obscure cinereous 
black, and the edges clear black, the shafts white. Primary 
and secondary quill feather, together with the tail, more or 
less grayish ; throat, breast, belly, and thighs clear or dull — 
rufous; toes somewhat granulated, and dusky black. Length 
about three feet. 
Young.—Head and neck brownish black ; upper parts gray- 
ish brown with blotches of dirty white; the anterior part of the 
back with large white blotches; the scapulars and wing coverts 
blackish with lighter colored spots ; the quill feathers brown- 
ish black; iris brown ; feet livid.—(Temmink.) 
This bird is found, though scantily, in most parts of South 
Africa, and is seldom seen in company either with those 
of its own species or of any other genus. It frequently resorts 
to spots where carrion occurs, and feeds upon it ; and it often 
also, according to the statements of the inhabitants, attacks 
and kills the smaller quadrupeds.
