The Sea-Hagle is not, on the whole, very critical in its 
choice of winter-quarters. It prefers large rivers and streams, 
and also selects districts where lakes and ponds will provide 
it with food, remaining close to them until they are quite 
frozen ; but from that moment it may be seen away in the 
interior of the plains, far from all water. Fish certainly form 
its chief diet ; but in winter, as soon as these fail, it pursues 
all sorts of game, from the doe of the Roe Deer down to the 
smallest vertebrate animal. It is indeed so fond of hares and 
rabbits that it even forsakes the waters and spends a long 
time in localities where these animals abound. 
Most of the Sea-Hagles build their nests on the shores of 
the northern seas, in Norway, Sweden, on the coasts of the 
German Ocean and the Baltic, in the great forests of Russia 
and Northern Germany, and in Mecklenburg, especially on 
the island of Riigen, which is one of their well-known 
breeding-places. It has also several favourite resorts along 
the large rivers of Southern Russia near the Black Sea, but 
never nests in Central Hurope proper. The only spots in our 
own country where it now breeds are situated in Southern 
Hungary, the Banat, and on the Danube down to the Servian 
frontier. } 
In spring the Sea-Hagles are of course busy at their nests, 
and until the young are fully fledged do not begin their 
travels, which at first only extend over a limited area in the 
neighbourhood of their breeding-places, the greater journeys 
commencing towards the middle of October, and in mild 
autumns even later. 
Many of these eagles naturally remain on the sea-coasts, 
chiefly on those of the northern waters, but numbers of 
them come down into the interior of Europe, and there
