174 FALCONID^B. 



189. Aquila rapax, Temminck. Tawny Eagle. 



This Eagle is included in Favier's list. I never saw but 

 one Spanish specimen, which, obtained near Malaga in winter 

 of 1877, is in Lord Lilford's collection, and was of the light

Little seems to be known of the plumage of this African Eagle,

The adult tawny birds are known to pair with the light-

General colour from rich reddish brown to light stone-colour. Length

Lower half of leg bare of feathers ; that and the toes covered in front 

 with large scales. 



Adult. Bill and iris light yellow ; head and neck much lighter than

Young. Bill blackish ; iris brown ; tail whitish, much mottled with 

 greyish brown. Length 28-34 inches.

 Aguila de las rocas.
