taken at this time contained eijfgs that would have been deposited within 

 a day or two. One bird was found incubating two eggs on September 6. 

 Unfortunately, however, these eggs were destroyed by some animal, and I 

 am unable to say whether they would have hatched. As no young were 

 seen, I am inclined to think that most if not all of the eggs deposited at 

 this late date were infertile. (See Zoe, Vol. I, p. 380.) 



15. Cathartes aura. Turkey Vulture. — After its appearance in April 

 it was common, and it probably nested in the region, as young were taken 

 in August. 



16. Circus hudsonius. Marsh Hawk. — Very abundant in September 

 and October, but very rare or not noticed during the spring migration. 



17. Accipiter velox. Sharp-shinned Hawk.— One seen on September 

 23 at Apache. 



iS. Buteo borealis calurus. Western Redtail. — Probably most of 

 the Redtails seen were winter residents. Rather common after late Sep- 

 tember and until April. 



19. Buteo abbreviatus. Zone-tailed Hawk. — A few were seen all 

 summer, but they were rather more plentiful in April, and seemed to be 

 moving north. A favorite resort was about a large prairie dog town in the 

 valley west of Apache. 



20. Buteo swainsoni. Swainson's Hawk. — But few were seen during 

 the spring and summer, but when the fall migration began they were very 

 abundant. On September 19, during a ride of forty miles across the 

 plains, several hundred large Hawks were seen, all moving southward in 

 companies of from two or three to fifteen. The percentage of species was 

 about: B.sivairisotti .^^^ B. borealis calurus .15, Circus hudsonius .10. 



22. Falco mexicanus. Prairie Falcon. — A single bird seen at Apache. 



23. Falco fusco-ccerulescens. Aplomado Falcon. — A pair was seen 

 in the valley between Apache and Hachita, June 2. 



24. Falco sparverius. American Sparrow Hawk. — Abundant as a 

 migrant. 



25. Pandion halia tus carolinensis. American Osprey. — Frequently 

 seen in spring and early summer; one shot April 14. The presence of 

 this species in the midst of this arid plain, seventy-five miles from the 

 nearest stream of water, was something of a surprise to me, and I am 

 still at a loss to account for their presence. It is quite possible that they 

 may have been passing from the Rio Gi^ande to the Gila River. 



26. Asio wilsonianus. American Long-eared Owl. — One shot in 

 the Little Hachita range, April 30. 



27. Bubo virginianus subarcticus. Western Horned Owl. — Rather 

 common in all of the ranges, seeking shelter in the scrubbj' junipers dur- 

 ing the day. 



A Megascops was several times seen at Apache, but I am in doubt as to 

 the species. 



28. Speotyto cunicularia hypogaea. Burrowinc; Owl. — More or less 

 common in all of the dog towns.
