BALD EAGLE. 21 
own sustenance without molesting the Osprey. ‘The circles he 
describes in his flight are wider than those of the White- 
headed Eagle ; he also flies nearer to the land or the surface 
of the water ; and when about to dive for his prey, he descends 
in circuitous, spiral rounds, as if to check the retreat of the 
fish, on which he darts only when within the distance of a few 
yards. When his prey is obtained, he flies out at a low eleva- 
tion to a considerable distance to enjoy his repast at leisure. 
The quantity of food consumed by this enormous bird is very 
great, according to the account of those who have had them 
in confinement. Mr, Audubon’s male bird weighed fourteen 
and one half pounds avoirdupois. One ina small museum in 
Philadelphia (according to the account of my friend Mr. C. 
Pickering), also a male, weighed much more, — by which dif- 
ference it would appear that they are capable of becoming 
exceedingly fat ; for the length of this bird was about the same 
as that of Audubon, — three feet six or seven inches. ‘The 
width, however, was only about seven feet, — agreeing pretty 
nearly with a specimen now in the New England Museum. 
The male of the Golden Eagle, the largest hitherto known, is 
seldom more than three feet long. 
That this bird is not the White-tailed Eagle (Fako adbi- 
cilla), or its young, the Sea Eagle (7. ossif/ragus), is obvi- 
ous from the difference in size alone, the male of that bird 
being little over two feet four inches in length, or a little 
less even than the Bald Eagle. The female of the Washing- 
ton Eagle must, of course, be six or eight inches longer, — 
which will give a bird of unparalleled magnitude amongst the 
whole Eagle race. This measurement of the Sea Eagle is 
obtained from Temminck’s “ Manual of Ornithology,’’ who has 
examined more than fifty individuals. At the same time I have 
a suspicion that the Washington Eagle, notwithstanding this, 
exists also in Europe; as the great Sea Eagle of Brisson is 
described by this author as being three feet six inches in length 
from the point of the bill to the end of the tail, and the stretch 
of the wings about seven feet! These measurements also are 
adopted by Buffon ; but the individuals were evidently in young
