Arr. [X.—Falco Leucocephalus—Bald Eagle. 
(Communicated by Professor Jacor Green, Sept. 1521] ~ 
December 23d 1820, I saw a large bald eagle shot in this 
neighbourhood. He measured seven feet and nine inches 
from the tip of one wing tothe tip of the other; three feet and 
four inches in length, and weighed sixteen pounds four or five 
weeks after he was killed. This is larger than the one men- 
tioned by Wilson, which measured seven feet from tip to 
us was three feet in length and weighed thirteen pounds. 
e bird shot here was probably not of full ee , as there 
was not the appearance of a white feather on the back of 
his head. This bird is usually called the Grey Eagle ; it 
is very uncommon with us, and so large a one [ think has 
never been described. If the accurate biogra of 
American Birds had not assured us that the Grey and Bald 
were of the same species, differing in colour only on 
account of age, I should have considered this of another 
_ Species. When first seen, the Eagle was in company with a 
flock of birds on the ground, near some stacks of grain with- 
in a few yards of the road. He exhibited no signs of fear, 
and even ruftled his feathers as if to make an attack, After a 
short time, he rose with difficulty and flew a short distance 
—when shot he clung by his talons to the branch of a tree 
upon which e was sitting for about a minute, and then as 
he was falling to the ground made a last effort 7" his 
wings, and moved from the place some yards; he was not 
quite dead when approached—but he made no cadhinse 
upon being taken up.
