20 RAPTORIAL BIRDS 
it is a remarkably fierce bird in its native state, and 
Mr. James Chapman, in his South African travels, re- 
lates a curious instance of his having been most 
pertinaciously attacked by one of these Eagles, at 
which he had fired when it was sitting on its nest. 
The Buzzard-Eagles are followed by the Sea-Eagles, 
of which there are nine species all comprised in the 
genus Halaétus. 
The Sea-Eagles are for the ‘most part powerful 
birds, frequenting the sea coasts and the larger rivers 
and lakes in every quartet of the globe, and feeding 
partly on fish and partly on other animal food of 
various descriptions. 
The largest and most powerful of the Sea-Eagles is 
the species inhabiting Kamskatcha, (ad/iaétus pelagicus) 
which is very rare in collections, and of which, though 
we possess two immature specimens, we have at pre- 
sent no adult example. 
The species which occasionally frequents in winter 
the eastern coasts of England, and which still nests 
in SOme mountainous parts of Scotland and Ireland, 
is the next in size to that inhabiting Kamskatcha, 
and much more extensively diffused, as it extends its 
range westward to Greenland, and eastward to Japan, 
and is found in most of the maritime countries of 
Europe and Asia, as well as of Northern Africa; it is 
usually called the white-tailed or cinereous Sea-Eagle 
(Haliaétus albic:lla). ‘The Norwich Museum possesses 
a grey variety of this Eagle, which is believed to be
