AQUILA CORONATA. 



of pure white or bright reddish orange ; and the feathers of the belly and the 

 tail coverts are tipped with one or other of these colours. Thighs externally 

 velvet-black, the feathers tipped and partially barred with white ; the tarsi 

 and thighs internally deep umber-brown, tipped and barred with white. Tail 

 coloured as in the adult. Base of lower mandible, edges of upper towards 

 the angle of the mouth, and the toes, yellow; the other parts of the bill and 

 claws horn colour, the latter lightest. 



Form, &c. — Figure rather more massive than that of the male, the feathers 

 of the crest rounded at the points ; in other respects the description of the 

 male will apply to the female.

There is every reason to believe tliat this is the bird figured as the " Imperial Eagle of 

 Africa," in Griffith's Animal Kingdom, and if so, it is an inhabitant of both Western and 

 Southern Africa, and has a similar range as Aquila hellicosa, which is found at Sierra Leone, 

 as well as at the Cape of Good Hope. In South Africa it inhabits the same districts as the 

 last-named species, and is only to be distinguished from it, when flying, by the comparative 

 shortness and roundness of its wings, and the great length of its tail. By these peculiarities it 

 is also readily distinguished from the other or more common species when in the hand ; and 

 if further proofs of difference are required, the markings of the tail and the character of the 

 crest will supply ample evidence of its being a distinct species. In A. coronata, there are only 

 three light-coloured bars to the tail, and all of these upon the last half of it; while in A. 

 beUicosa there are seven light-coloured bars, part of them on the first half The crest, in the 

 first-mentioned, is strongly developed at all ages; in the last it is only rudimentary, both 

 in youth and in advanced age. It feeds, like its congener, upon small quadrupeds, &c., but 

 is not so active in seizing" them, probably owing to the greater imperfection of its wings. It 

 builds its nest on lofty trees, and lays two eggs.
