Common summer resident, breeding throughout its range. Arrives 

 early in April. The bulk depart about the middle of September, but 

 stragglers often remain until the end of October. 



This bird is very destructive to young poultry and the small insec- 

 tivorous birds. 



(333) Cooper's Hawk. 



(Accipiter cooperi.) 



A summer resident, but not nearly so abundant as the last. Breeds 

 in the interior of the Province. 

 A very destructive hawk. 



(334) Goshawk.

 opportunity. 



GENUS BUTEO. 



(337) Red-tailed Hawk. 



(Buteo borealis.) 



A common summer resident, breeding in the interior. Arrives early 

 in March, departs at the beginning of November. A few have been 

 seen in winter. 



A dark form of this hawk now given sub-specific rank as the West- 

 ern Red-tailed Hawk, B. b. calurus, has been occasionally taken in On- 

 tario. 



This is one of the most useful species, feeding largely upon meadow 

 mice, grasshoppers, and frogs. 



(339) Red-shouldered Hawk. 



(Buteo lineatus.) 



Common summer resident. Less frequently seen than the last, or 

 perhaps more local in its distribution. Breeds in the interior. Arrives 

 a little later than the Red-tail and leaves towards the end of October. I 

 have seen specimens in winter, but not often. 



A very useful hawk, feeding chiefly on mice, reptiles and grass- 

 hoppers.
