ARCHIBITEO FEHKIGINEIIS (Lichtenstein). (348.) 



FERRUGINOUS ROUGH-LEG. 



I am very familiar with this hawk in his characteristic 

 home, California, and was the more surprised to find that indi- 

 viduals of the species have several times straggled into Min- 

 nesota. 



It is thoroughly a dry-prairie raptor, and lives upon small 

 rodents, reptiles and insects. It is rather a common hawk in 

 Dakota, especially in the western part where I found it perched 

 on prairie-dog's hills, or skimming leisurely along the ground 

 during the month of May of the present year (1887), but I 

 had no opportunity to look into their nests. On the other 

 coast they were very abundant, and voracious eaters, living 

 upon ground squirrels chiefly.
