186 THE CONDOR Vol. XXVI 



Buteo borealis calurus. Western Red-tailed Hawk. Seen frequently during the 

 whole of our stay. 



Archibuteo ferrugineus. Ferruginous Rough-legged Hawk. First seen October 

 9. Fairly common thereafter, and seen to the end of my stay, November 1. On one 

 occasion a Ferruginous Rough-leg and a Western Red-tail were seen perched on the 

 ground about twenty feet apart, each with a freshly killed prairie dog. 



Aquila chrysaetos. Golden Eagle. Of frequent occurrence. Sometimes five or 

 six seen in one day. 



Falco mexicanus. Prairie Falcon. Encountered at frequent intervals during the 

 whole of our stay. Once observed in pursuit of domestic pigeons in Flagstaff, and 

 several times after poultry about ranch houses. The one specimen preserved was shot 

 while making off with a chicken. 



Falco columbarius, subsp.? Pigeon Hawk. Two seen on the outskirts of Flagstaff, 

 October 31 and November 1, respectively. 



Falco sparverius sparverius. Sparrow Hawk. Common during September, and 

 early in October. A single bird seen October 31 was the only one noted after Oc- 

 tober 15. 



Otus asio, subsp.? Screech Owl. The call of a screech owl was heard several 

 times during the night of October 15 in pinon and juniper woods thirty miles north of 

 San Francisco Mountain. 



Bubo virginianus, subsp.? Horned Owl. Heard hooting occasionally; apparently 

 not numerous. 



Dryobates villosus leucothorectis. White-breasted Woodpecker. A few seen, 

 mostly in the pine woods. Late in October individuals occasionally strayed down to 

 lower levels. 



Sphyrapicus varius nuchalis. Red-naped Sapsucker. Two seen October 13 in 

 junipers near a tank. 



Sphyrapicus thyroideus nataliae. Williamson Sapsucker. First noted September 

 14, in the pines, and on several occasions thereafter. On October 10, 11, and 17, others 

 were seen in junipers, far from the mountain. 



Asyndesmus lewisi. Lewis Woodpecker. A few seen near Flagstaff early in 

 September. 



Colaptes cafer collaris. Red-shafted Flicker. Fairly common, mostly in the pines 

 during September; descending into the pinon and juniper woods in October. 



Phalaenoptilus nuttalli nuttalli. Poor-will. Last seen September 29. 



Aeronautes melanoleucus. WhitS-throated Swift. A few seen at irregular in- 

 tervals. 



Sayornis sayus. Say Phoebe. A few seen early in September. 



Empidonax griseus. Gray Flycatcher. An immature male, still undergoing the 

 post-juvenal molt, was collected in juniper woods September 6. An unidentified 

 Empidonax seen October 5 was the only other individual of this genus that was seen. 



Otocoris alpestris leucolaema. Desert Horned Lark. The horned larks col- 

 lected all appeared to be migrants. During the first two weeks in September they were 

 rare. Then flocks appeared more and more frequently, and by the middle of October 

 they were abundant, though restricted to certain favored localities. The twenty-eight 

 specimens collected, from September 11 to October 26, appear to belong all to the 

 same subspecies. 



Cyanocitta stelleri diademata. Long-crested Jay. Abundant in the pines along 

 the road between Deadman Plat and Flagstaff. Decidedly rare in the pine woods on 

 the northern slope of San Francisco Mountain. Merriam speaks of its occurrence 

 "everywhere from timber line to the lower part of the cedar belt," but I saw none in 

 the pinons and junipers. Two immature birds collected September 14 are in the 

 midst of the post-juvenal molt. In the northern subspecies, stelleri and annectens, 

 this molt is usually accomplished by the end of August. 



Aphelocoma woodhousei. Woodhouse Jay. Rather uncommon, and, as noted by 

 Merriam, usually "shy and difficult to procure." Restricted to the pinon-juniper belt. 

 In the lower portion of this belt there are far more junipers than piiions; in the upper 

 portion the pinons preponderate markedly. The Woodhouse Jay was always among 

 piiions, although this year there were no cones on any of the trees. The juniper woods.
