440 MISCELLANEOUS NOTES 
range about, following the upward course of the rivers; 
while others, especially those which nest in Southern Europe, 
extend their journeys to Asia Minor and Egypt, and there 
pass the winter. Their autumn migrations are quite irre- 
gular, for they are not true birds of passage, and seek no 
milder climate, but, like all the eagles, travel about in search 
of hunting-grounds. One day they spend in northerly, 
another in more southerly districts, just as their hunting 
necessitates; and this is the reason why we find the Sea-Hagle 
in all parts of Central Europe, even more frequently than the 
“Stein”? Eagle. Although the latter nests in the heart of 
our continent, in the Swiss Alps, Spain, the Pyrenees, and so 
many of the extensive forests of Hurope, still the Sea-Hagle, 
which sets up its abode further from us, is a much commoner 
bird, for its numbers are far greater. The number of eggs 
which it lays is also almost invariably larger, for a nest of the 
“Stein” Hagle is rarely tenanted by more than one young 
bird; but it is not uncommon to see three Sea-Eaglets in a 
single eyrie. Fish being the principal food of the Sea-Hagle, 
it is naturally in a position to bring up its young much more 
easily, and its cunning wary habits also enable it to avoid 
more dangers than the dashing “ Stein” Hagle. Seldom are 
more than two, at most three, of the latter birds seen at the 
same moment, while on the northern coasts of Hurope, as 
well as at their breeding-places in Southern Hungary, the 
former may be met with in companies of seven or eight, or 
even more. In all well-watered localities, where excessive 
cultivation does not make its free robber-life impossible, it is a 
winter resident ; but there are certain districts which, by 
reason of their special qualifications, yearly harbour great 
numbers of these birds. There they pass a shorter or longer 
time, and are always replaced by others. The auen of the 
Danube, close to Vienna, are, for example, one of their 
favourite winter resorts, and in former times especially, when
