The Eed-shouldered Hawk, called Hen Hawk by the 

 farmers, is the commonest hawk in southern New England 

 and the lower Hudson Valley. It is a permanent resident, 

 but less common in winter than in summer in the northern 

 portion of its range. It becomes rare at the edge of the 

 Canadian Zone. It may be seen circling high overhead, 

 often screaming tee'-ur tee'-ur, or a pair may be seen over

 for mice or frogs in the low meadows or swampy grounds. 

 The Red-shouldered Hawk is not swift enough to pursue 

 many birds on the wing, as the Falcons and Accipiters do ; 

 it either watches the ground from a perch, as above de-

 or trees beneath it for mice, squirrels, rabbits, and occasion-

 and drops swiftly down upon it. 



Adults have reddish-brown under parts, and may be 

 thus distinguished from Red-tailed Hawks ; but immature

 differ, and in spring and summer are excellent means of
