THE WHITE-TAILED EAGLE. 
HALIAETUS ALBIC{LLA (Linnzeus). 
Immature examples of this species—also called Erne, Cinereous or 
Sea-Eagle—are not unfrequently observed in the maritime counties 
of England in autumn and winter, at the time when the birds reared 
in the northern parts of Europe are on their migration southward, 
but adults are of very rare occurrence. Within the last hundred 
years the White-tailed Eagle bred in the Isle of Man and the Lake 
district ; in comparatively recent times in Galloway, Dumfriesshire, 
and other places on the south-western mainland of Scotland, and not 
long ago in Argyll; but now its eyries are confined to some of the 
western and northern islands. In Ireland, where it was formerly 
more numerous than the Golden Eagle, its propensities for carrion 
have led to its destruction by poison, and only on the west coast 
can a pair or two be found.
