ARCHIBUTEO FERRUGINEUS (LicHTENSTEIN). (848.) 
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 acommon 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.
