8 BIRDS OF DAMARA LAND. 



fully ; it perches on trees and rocks, and is fond of re- 

 turning to the same tree or other post of observation. 

 Its food consists of small quadrupeds and birds of all 

 kinds. 



The hides are yellow, but paler in the immature than 

 in the adult bird ; the toes, cere, and basal part of the 

 mandibles greenish yellow ; the anterior part of the bill 

 dark horn-colour, almost black at the point.

[It appears to me that this and the succeeding species be- 

 long most properly to the genus Pseudaetus of Hodgson, of 

 which the type is the Bonellr's Eagle (Aquila fasciata of Vieil- 

 lot), to which the present species, in particular, is very closely 

 allied. 



An individual of this species, which was incorrectly identified 

 by me some years since as Aquila Bonellii (= fasciata), led Mr. 

 Layard into the error of introducing the latter species into his 

 Catalogue of South-African Birds, loc. cit. ED.]

I never identified but one pair of these Eagles, which 

 I found close to Objimbinque, and the female of which 

 I killed ; they were both very wild, always perching on 

 the topmost branches of the loftiest trees.
