pi. 8 and 9j Wils. VII, Iv, 1. (The Common Eagle.) More 

 or less brown; the occiput fawn coloured; the superior half of 

 the tail white, and the remainder black. The most common 

 species in all mountainous countries. 



F. chrysaetos, Enl. 410. (The Ring-Tail Eagle.) Only differs 

 from the preceding in its blackish tail, marked with irregular 

 ash coloured bands. We are assured that it is the Common 

 Eagle, with its perfect plumage. (l) 



F. imperialism Bechst. ; F. mogilnik, Gm.; Aqiiila heliaca, 

 Savig. Eg. Ois. pi. xiii; Vieillot, Gal. 9; Naum. pi. 6 and 7. 

 Tem. Col. 15 and 152. (The Imperial Eagle.) Still longer 

 wings; a large whitish spot on the scapulars; the nostrils trans- 

 verse; the tail black; the superior portion undulated with grey. 

 The female is fawn coloured, with brown spots. Its port is 

 heavier than that of the Common Eagle, and it is a still more 

 fearful object to other Birds. It inhabits the high mountains 

 of the south of Europe, and is the true subject of the exagger- 

 ated tales propagated by the ancients, relating to the power, 

 courage, and magnanimity of their Golden Eagle. 



F. nsevius, and F. maculatus, Gm. ; Naum. pi. 10 and 11; 

 Aq. melanaetos, Savig. Eg. Ois. pi. 1 and pi. 2, f. 1. (The 

 Spotted Eagle.) A third less than the two others ; tarsi more 

 slender; plumage brown ; tail blackish, with paler bands; pale 

 fawn coloured spots, form a band on the small coverts; one at 

 the tips of the large ones which mounts to the scapulars, and 

 one at the tips of the secondary quills. The superior part of 

 the wing is sprinkled with fawn colour. The old birds become 

 all brown. This species is common in the Apennines, and other 

 mountains of the south of Europe ; but is rarely seen in the 

 north; it attacks the weaker animals only. It has been found 

 sufficiently docile to be employed in falconry, but is said to fly 

 from and be vanquished by the Sparrowhawk. 



It has been thought proper to place among the Eagles a bird 

 of Eastern Europe Falco pennatu.s, Gm.; Col. 33.; Briss., 

 Suppl. pi. 1, which scarcely resembles them in any thing except 

 the plumed tarsi and pointed feathers of the vertex, but which 

 is not as large as the Buzzard, and has a beak almost as much 

 curved; its plumage is fawn coloured spotted with brown, its 

 feet blue. Very rare in France and Germany-(2) 



in pi. Enl. 409. Finally, the F. Niger, or Black-backed Eagle of Brown, is merely 

 a slight difference of age.
