irk*. Between the 1'urht and dark phases of coloration there is every 

 degree of intcrgradation, but in any plumage this Hawk may be distinguished 

 from our other species by having only thret outer primaries notched. In this 

 respect it agrees with //. l>iti*imut, from which, however, it differs decidedly 

 both in size and color. 



Ranyt. Western North America, eastward to the Mississippi; breeds 

 from Texas to the arctic regions, and occasionally strays eastward to the At-

Swainson's Hawk is of rare occurrence ea*t of the MisMs-ippi. Dr. 



her writes : " By preference it frequents the timber in the vicinity 

 of streams, though often it is found far out on the prairie, where its 

 only perch is the earth mound of some mammal, or some other 

 slightly elevated knoll."
