" Of all our Hawks, this species seems to be the most unsuspicious, 

 often allowing a person to approach within a few yards of it, and 

 when startled flies but a short distance before it alights again. Dur- 

 ing the early summer the Broad-winged Hawk often may be seen sit- 

 ting for hours on the dead top of some high tree. At other times it 

 is found on the smaller trees in the deep woods, along streams, or on 

 the ground, where its food is more often procured. Although slug- 

 gish and unusually heavy in its flight, it is capable of rapid motion, 

 and sometimes soars high in the air. One of its notes resembles quite 

 closely that of the Wood Pewee. . . .
