This hawk appears to be rather numerous in" Southeastern Aiizona, 

 especially about Camp Lowell, where I saw several. I have never had 

 opportunity to observe their habits ; but these are tolerably well known, and 

 probably do not differ in this region from their usual manners elsewhere. 

 I saw one in hot pursuit of a Mallard Duck one day, and the latter appeared 

 to maintain well the advantage of a dozen feet which it had, though its ulti- 

 mate fate could hardly have been doubtfiil had not the hawk, observing 

 me, given over its design, and retired, to be met with again a few minutes 

 later and secured.

1 am quite confident that 1 saw this species once or twice in Southern 

 Arizona, and at least once in New Mexico, on the upper sources of the Gila. 

 It is given by Dr. Coues, in liis " Prodrome of a Work on the Ornithology 

 of Arizona Territory," as a conunou resident.
