ZOOLOGY— BIRDS. 



Although seen several times in the mountains during the summer, none 

 ■were obtained until we reached 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 sun'ounding marshes attract multitudes of water- 

 fowl; and this undoubtedly explains in part the abundance of hawks at this 

 season, since wounded and disabled ducks must fonn no inconsiderable part 

 of their food. In its manner of hunting it much resembles the foregoing 

 species, and like it subsists to a great extent upon mice, which are very 

 numerous in the rushes. In the stomachs of every individual captured were 

 found the remains of these little animals. 



I saw several of these hawks near Colorado Springs, Colo., in Novem- 

 ber, where, however, I was told by Mr. Aiken he had never seen it.
