92 THE RAPTORIAL BIRDS OF IOWA 



A. K. Fisher says, "The food of this hawk consists largely of offal, 

 the smaller reptiles and mammals, and occasionally birds. Mr. C. C. 

 Nutting states that a specimen obtained in Costa Rica was shot while 

 in the act of carrying off a chicken." (Proc. U. S. Nat'l Mus., Vol. 

 5, p. 404, 1882.)
