SHARP-SHINNED HAWK. 195 



This is one of those birds regarding which the idea prevailed that 

 they took game and poultry, and should therefore be killed whenever 

 they came within reach. But the evidence shows that the Marsh 

 Hawk does so only on very rare occasions. It does so much good 

 by the destruction of injurious rodents, that I hope in future it will 

 be allowed to follow its course in peace.

This is a rather common summer resident in Southern Ontario, 

 smaller in size than Cooper's Hawk, but similar in markings. It 

 lives chiefly on small birds, and nothing can exceed the impetuosity 

 with which it dashes down and captures them by sheer power of 

 flight. 



" Many have been the times," says Audubon, "when watching this 

 vigilant, active and industrious bird, have I seen it plunge headlong 

 into a patch of briers, in defiance of all thorny obstacles, and passing 

 through, emerge on the other side, bearing off with exultation in its 

 sharp claws a finch or a sparrow which it had surprised at rest." 



This species 'is much given to variation in size and markings, 

 making it difficult at times to distinguish between a large Sharp- 

 shinned and a small Cooper's Hawk. In the present species, the legs
