AQUILINE. 199 



The breeding-range of the White-tailed Eagle extends from the 

 British Islands across Europe and Siberia to Japan. 



As it is only a winter visitor to South China, it must be regarded 

 as a Palaearctic species which probably emigrated to Japan from 

 Siberia.

 (STELLER'S SEA-EAGLE.) 

 Aquila pelagica, Pallas, Zoogr. Rosso-Asiat. i. p. 343 (1826). 



Steller's Sea-Eagle may always be recognized by its wedge-shaped 

 tail, consisting of 14 (instead of 12) feathers. It is about the same 

 size as the White-tailed Eagle, but has a larger bill.

Steller's Sea-Eagle is a frequent winter visitor from its breeding- 

 grounds in Kamtschatka to the Japanese Islands, but is more often 

 seen in Yezzo than further south (Blakiston and Pryer, Trans. As. 

 Soc. Japan, 1882, p. 180). Mr. Henson has sent several examples 

 from Hakodadi, three of which are in the British Museum. There 

 are two examples in the Pryer collection from Yezzo (Seebohm, Ibis, 

 1884, p. 183), and one from the central group of the Loo-Choo 

 Islands (Seebohm, Ibis, 1888, p. 232), the latter having been caught 

 exhausted in a paddy-field. 



The breeding-range of Steller's Sea-Eagle is probably confined to 

 the shores of the Sea of Okhotsk. 



183. AQUILA CHRYSAETUS. 

 (GOLDEN EAGLE.) 



Falco chrysaetus, Linneus, Syst. Nat. i. p. 125 (17GG). 



The Golden Eagle is not quite so large as the Sea-Eagle (wing 

 from carpal joint 28 to 22 inches). Its tarsi feathered to the toes, 

 the absence of bars on the thighs and the rest of the underparts, and 

 its large size, prevent it from being confounded with any other Japa- 

 nese bird of prey.
