 The Red-shouldered Hawk is not swift enough to pursue 

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

 and drops swiftly down upon it. 



Adults have reddish-hroimi under parts, and may be 

 thus distinguished from Red-tailed Hawks ; but immature

 distinguished unless killed. The notes of the two, however, 

 differ, and in spring and summer are excellent means of
