This handsome hawk is given by Dr. Coues as common about Fort 

 Whipple, Ariz., especially in winter, but as apparently resident. In East- 

 ern Arizona, on the contrary, I have not seen it at all ; and if it occur there, 

 it must, I think, be rare, and only in winter. In Northern New Mexico 

 and Southern Colorado, it was quite numerous in November, 1873 ; and Mr. 

 Aiken has taken quite a number of them in El Paso County, they returning 

 from the mountains, their summer home, and dwelling in winter on tlie 

 open plains and along the streams. Their prey consists principally of the 

 small mammals, — mice and ground squirrels, — to secure which they fly a few 

 feet from the ground.
