BLACK-HACKED EAGLE. 



Falco melanotus. F. fusco-ferrugineus, gula pectore dorsoque 



nigris, cauda nigra basi alba. 

 Brown-ferruginous Eagle, with the throat, breast, and back 



blaek, the tail black with a white base. 

 Black-Backed Eagle. Brown's Illustrations of Zoology, pi. 2. 



Lath, synops. 



Said to be of the size of the Golden Eagle ; and 

 is of similar colour, but with the fore part of the 

 neck and breast, the back and quills black : the 

 tail, from the base to the middle, white -, the end- 

 half black: the bill black, with a yellow cere, 

 the legs yellow, but covered to the toes with 

 ferruginous feathers. Native place unknown. 

 Described merely from a figure in Brown's Illustra- 

 tions of Zoology, and, as Sonnini very properly 

 observes, may be no other than a mere variety of 

 the Black Eagle, (Aigle Commun Buff. ) It is at 

 all times dangerous to describe animals merely 

 from figures, unless we could be well assured that 

 the artist was himself a Zoologist.
