THE MUSEUM. 



Infusorial Earth, highly magnified. 



the same belt of timber from which I 

 took set No. 4, and only about thirty 

 or forty yards from the other nest. 

 As I had seen no other owls in this 

 wood I think it was the same pair that 

 furnished this set for my cabinet. Bird 

 left nest when I threw stick up near 

 her. Nest poorly built, though nicely 

 lined with feathers. Two eggs, fresh. 



Nest No. 8, March 5, '96. — Situated 

 in crotch of Black Jack, thirty-six feet 

 from ground, in large belt of timber 

 bordering the Arraya Blancs. This 

 nest was quite a flimsy affair and the 

 bird could be seen very plainly from 

 the ground. Had some moss as well 

 as feather lining. Bird was on the 

 nest, which was that of a hawk. Three 

 eggs, in which incubation was ad- 

 vanced. 



Nest No. 9, March 7, '96. — This 

 nest was situated in the top crotch of 

 a small blackberry, near the Chocolate 



Creek, only about thirteen feet from 

 the ground. Hawk's nest of usual 

 compaction and customary lining — 

 owl feathers. The bird left the nest 

 only when I was about to put my han<l 

 into it. Contained two eggs about 

 one-third advanced in incubation. 



Nest No. 10, March 8, '95. — Poorly 

 made hawk's nest of sticks, though 

 nicely lined with feathers and moss. 

 Situated sixteen feet from ground in 

 Black Jack. The bird was on the nest 

 which contained two eggs, in which 



incubation was begun. 



From the foregoing I decided that 

 the horned owls begin housekeeping 

 soon after Christmas and near New 

 Year in this country. That they move 

 often, appropriating the nests of 

 hawks and the Caracara, though the 

 the nests of the later are as pleantiful 

 as the former, therefore their reason 

 is best known to themselves.
