With the general habits of the two preceding species this larger 

 bird is much bolder than either. Dr. Fisher remarks : " This species 

 is one of the most daring of all the Hawks, and while in pursuit of 

 its prey is apparently less concerned by the presence of man than any 

 other. It will dart down unexpectedly at the very feet of the farmer 

 and carry off a fowl." 



" Of 28 stomachs examined, 9 contained poultry or game birds ; 2, 

 other birds; 10, mammals ; 3, insects ; 1, centiped ; and 8 were empty " 

 (Fisher).

The Red-tailed Hawk resembles its near relative, the Red-shoul- 

 dered Hawk, in the selection of its haunts, and, to a large extent, in
