34 CLASS AVES. 



M. Temminck considers the Common and Ring- 

 tailed Eagles as mere varieties of age, the latter being 

 full-grown. 



The Spotted and Bough-footed Eagle, (F. navius et F. 

 maculatus, Gm.) Savigny, Ois. d'Egypte, t. 2. f. 1. Adult, 

 t. 2, f. 1. Jun. F. melajiaetos, Sav. 



A third smaller than the other two ; brown ; tail 

 black, with the tip whitish ; some pale yellow spots 

 form a band over the small coverts, one at the end of 

 the great feathers, which mounts on the scapulary 

 feathers, and one at the end of the secondary. The 

 top of the wdng has little yellow dots ; the under part 

 of the body is paler than the back^ and the tarsi are 

 thinner and less furnished than in the great eagles. 



This species is common in the Apennines and other 

 mountains of Southern Europe, but is rare in the 

 north. It attacks only very weak animals. It has 

 been found docile enough to be used in falconry, but 

 it is said that it flies from and submits to the sparrow- 

 hawk.
