 of oiu' o\' the mosi dostruclive enemies of poultry. Its size, strength 

 aiul iictivity and rapacity, added to its well-known fearlessness, render 

 il, in localities where it is common, a great pest. Besides poultry, they 

 oat. K'ulVed Grouse. Bobwhites and Doves, Rabbits and Squirrels. The 

 report by Dr. A. K. Fisher on 28 stomachs of this species examined 

 show that 9 contained poultry or game birds; 2, other birds; 10, mam- 

 mals; ;>, insects; 1, centipede, and 8 were empty (Bull. No. 3 Division 

 of Orn. and Mam.. T. S. Dept. of Agriculture, p. 46). 



In some localities the Goshawk so persistently hunts the Ruffed 

 Grouse that it is commonly known as "Partridge Hawk." Audubon 

 tells us that, as he was passing down the Ohio, he observed one of these 

 Hawks attack a flock of Grackles, which were crossing the river, and 

 kill four or five of them. After killing each one by a squeeze, it was 

 permitted to fall on the water. The Hawk finally returned axid picked 

 up all the floating birds. 



in appearance, it is sini[)ly a larger Cooper's Hawk, which species it 

 resembles in its flight and its hunting habits and its nesting. 



It is said to breed in Michigan (Cook, Birds of Mich., p. 74), and in 

 llu" mountains of Pennsylvania, where it has been noted by Dr. War- 

 ren (The .\id<. July. 1897, pp. 317, 318).
