REPORT UPON ORNITHOLOGICAL SPECIMENS. 



25 



On a stream near Fillinore, six of these owls were taken within a 

 radius of half a mile, and many of their old nests being seen, there 

 seems no reason to doubt but that this was a favorite breeding-ground. 



tfpeotyto cunicularia, var. hypugcca Bp. (Mol.) Prairie-Owl. 



Seen in but two localities in Utah, Dog Valley and near Pauquitch 

 Lake. Not very numerous-, living with prairie-dogs. 



Fak'o sparverius, L. Sparrow-Hawk. 



Very common in Nevada and Utah. Seen frequently in the mount- 

 ains ; subsists largely upon grasshoppers. 



Xisusfuscus, (Gm.) Sharp-shinned Hawk. 



Not uncommon in Nevada and Utah. A beautiful adult pair were 

 taken in Beaver Canon September 24. Upon one occasion, while watch- 

 ing a pair of doves feeding upon the ground, a female of this species 

 made a daring and successful swoop upon one of them, passing within 

 a few feet of the observer's head. As a further illustration of the brav- 

 ery and hardihood with which this bird pursues its prey, it may be 

 mentioned that one was observed in the town of Pauq-uitch eagerly 

 pursuing a common pigeon, apparently oblivious of the presence of 

 spectators, who, for some time, vainly endeavored to drive it away. 

 Such was its determination that it actually followed the pigeon into a 

 deserted house, but was finally obliged to retire without accomplishing 

 its object. 



Buteo borealis, (Gm), var. calurus Cass. 



A fine adult female was secured at Otter Creek, Utah, in September. 

 Observed at intervals during the entire season, generally in the mount- 

 ains.* 



Archibuteo lagopus, (Bruin.), var. sancti-johannis GUI. Black Hawk. 



Although seen several times in the mountains during the summer? 

 none were obtained until at Provo, where it was the most numerous of 

 the hawks. At this place, from November 25 until December 4, no 

 less than eleven specimens were taken, representing the bird in all 

 stages of plumage. On foot it was extremely difficult to approach this 

 hawk, but it could be ridden up to with ease; most of the specimens 

 being shot in this way from the back of a mule. 



Utah Lake and the surrounding marshes attract multitudes of water- 



" It may be mentioned that in the road from Saint George to Beaver, late in the 

 i>;\^m, several Buteos were observed not calurus, but probably allied to lineatus, as it 

 resembled it in form and flight.
