KRIDER'S HAWK 



109 



Range. From North Dakota and Minnesota south to Missouri, 

 wintering southward. Accidental in Alaska. 



The Krider's Hawk is but a light form of the Red-tailed Hawk. 

 The type specimen of this species was taken in Winnebago county, 

 Iowa, September, 1872, and while not to be considered common, it is 

 now and again reported, and specimens are occasionally collected 117 

 the state. 



It has been found nesting in several counties, and its breeding 

 habits and food are in no way distinctive. Mr. Jasper Brown noted 

 several mice in a nest containing two eggs, near Middle Amana, Iowa 

 county, March 24, 1898. 



A specimen of Krider's Hawk taken in Eagle, Alaska, was pre- 

 sented to the Coe College Museum (No. 336) by Rev. Dr. C. F. En- 

 sign, who for some years was a missionary at that station. Hitherto 

 it had not been found north of North Dakota. 



The report of stomach contents of this form will be found listed 

 with that of the Red-tailed Hawk, the variety being indicated.
