thirty of their eggs. I had previously taken memoranda as to where 

 I had generally noticed them, and ] obtained them all in little more 

 than two hours. I am greatly surprised at the extreme variations in 

 their eggs, both in size and color. I have them from nearly a pure 

 white to the color of the eggs of Lagopus albus. Their eggs are five 

 in number. Excepting one taken in a hollow pine stump, with the 

 entrance on the top, they were all in old woodpecker's holes." 



54. Astur atricapillus Bon. "May 26th. I took a nest of 

 this species, but was a little too late. Tt contained two youno- ones 

 and one egg out of which the young had already broken a piece." 



55. Buteo calurus Cassin. "May 26th. I have just found 

 a nest of this species, the first one I have seen here. Both this one 

 and that of Astur atricapillus, were in the pine timber on the moun- 

 tains."

 specimens of this species, both males, and in light plumage. On the 

 18th of February, I also obtained a fine male. Of the four speci- 

 mens so far taken, all have been males. — March 6th. I obtained a 

 very fine dark male in the plumage of Sancti-Johannis." 



59. Aquila canadensis Cassin. This species is said to breed 

 in close proximity to Camp Harney. 



60. Haliaetus leucocephalus Savigny. This eagle is also 

 said to be common, and to breed near the post. " February 16th. 

 One of the men found a specimen of this species nearly starved to

61. Canace fuliginosus Kidgway. December 5th. Mention 

 is made of finding this species and C. Richardsoni both common, and 

 shooting a female of this species. — " December 28th. Our express
