 .prize, and bears it away to some secluded place and 

 devours it. Sometimes it sweeps over the water and 

 catches up ducks and other swimming birds. This 

 falcon is about a foot and a half in length. The Pere- 

 grine Falcon of Europe, very much like this species, 

 was formerly much used in falconry, a fashionable

The Sparrow Hawk, of Amer- 

 ica, is the smallest of the hawks, 

 being but little larger than the

 small birds, mice, and insects. 

 It becomes attached to a partic-

 day after day on the same tree 

 or stump watching for prey.

 the deep, and, as he emerges with his prey and rises into 

 the air, the Eagle gives chase ; each moves with its ut- 

 most speed, but the Eagle rapidly gains, and as it is 

 about to reach the Hawk, the latter drops the fish ; the 

 Eagle sweeps downward, snatches it before it reaches 

 the water, and bears H away to the woods
