THE FERRUGINOUS ROUGH-LEGGED HAWK. 



Length, 22 inches. 



This Hawk may be distinguished from the pre- 

 ceding one by noting that its name, " Ferrugi- 

 nous," refers to its reddish coat, a color suggested 

 by iron rust, though sometimes this bird, too, is of 

 dark plumage, almost of a chocolate shade, but 

 varied with reddish-brown. He is a fine, striking 

 specimen of the Hawk family, and with his rela- 

 tive, the American Rough-legged Hawk, should 

 not be killed unless actually found making depre- 

 dation upon poultry.
