along in a silent gliding manner, with a swiftness even superior to that of 
the Wild Pigeon ( Columba migratoria), seldom deviating from a straight- 
forward course, unless to seize and secure its prey. Now and then, but 
seldom unless after being shot at, it mounts in the air in circles, of which 
it describes five or six in a hurried manner, and again plunging down- 
wards, continues its journey as before. 
The daring exploits performed by this Hawk, which have taken place in 
my presence, are very numerous, and I shall relate one or two of them. 
This marauder frequently attacks birds far superior to itself in weight, and 
sometimes possessed of courage equal to its own. As I was one morning 
observing the motions of some Parakeets near Bayou Sara, in the State of 
Louisiana, in the month of November, I heard a Cock crowing not far from 
me, and in sight of a farm-house. The Cooper’s Hawk the next moment 
flew past me, and so close that I might have touched it with the barrel of 
my gun, had I been prepared. Its wings struck with extraordinary rapidity, 
and its tail appeared as if closed. Not more than a few seconds elapsed 
before I heard the cackling of the Hens, and the war-cry of the Cock, and at
