May, 1908 SOME FALL MIGRATION NOTES FROM ARIZONA 109 



is uniform with the rest, and does not form a lighter brown spot, as I have seen in 

 some adults in this phase of plumage. There is no trace of red on the tail. 



Buteo swainsoni. Swainson Hawk. While travelling west from Chicago a 

 great many Swainson Hawks were seen from the car window on September 20, in 

 eastern New Mexico and western Texas. They were observed at quite a high 

 altitude, 5000 to 6000 feet, and the air was decidedly frosty; so it seemed the more 

 strange to find that they had entirely left their summer home on the "Huachuca 

 Plains" before we reached there. There was an abundance of food for them in 

 the shape of grasshoppers, but the hawks had all gone. 



Aquila chrysaetos. Golden Eagle. On October 26 I secured a fine old male 

 Golden Eagle on the extreme summit of Carr Mountain, the second highest peak 

 in the range. He had not quite finished his fall moult, a few old feathers remain- 

 ing in the lesser wing coverts, and a few pin feathers on the dorsum, while an old tail 

 feather showed that the immature plumage had not been worn during the previous 

 year at any rate. Eagles were seen almost daily during our stay in the mountains, 

 most frequently toward the top of the range. Several were observed in 

 the Rincons. 



Falco peregrinus anatum. Duck Hawk. On September 30, as I sat on the 

 veranda of the hotel at Benson, waiting the arrival of the train, a Duck Hawk 

 passed directly over me, not thirty yards distant, quite close enough for me to see 

 that it was an old bird, from its size probably a female. This was the only one of 

 the species seen on the trip. 



Falco columbarius. Pigeon Hawk. A single bird in the beautiful blue plum- 

 age of the fully adult male was secured on October 30, on the open prairie below 

 the Huachucas. Another, probably of the same species, was seen on October 24. 

 The Pigeon Hawk appears to be of quite. rare occurrence in the region, this being 

 the only one I have secured. I have never seen Falco richardsoni'sX all, though it 

 also certainly should occur. 



Falco sparverius phaloena. Desert Sparrow Hawk. Not nearly as common as 

 during the summer months. Seen in the foothills and out on the plains, but not 

 high up in the mountains. A male bird secured on October 16 was still in the 

 midst of the moult. 



Syrnium occidentale. Spotted Owl. Heard calling on several occasions in the 

 higher parts of the Huachucas. None were seen and no specimens secured. 



Megascops asio cineraceus Ridgway. Mexican Screech Owl. Screech Owls 

 were frequently heard calling in the evenings around our camp in the Huachucas, 

 sometimes three or four answering each other from different points in the woods. 

 Cineraceus is the common screech owl of this region, tho flanimeolus and trichop- 

 sis also occur, and it is very possible that more than one species contributed to 

 these nightly concerts; there was variety enough of sound for a dozen. No speci- 

 mens were secured. A few, but very few, were heard in the Rincons. 



Bubo magellanicus pallescens. Western Horned Owl. Quite common in the 

 Huachucas, frequently seen in the daytime, and heard calling almost every night. 

 I was often directed to them by the blue jays, the commotion stirred up when the 

 jays found an owl being audible a long ways from the center of the disturbance. 



Speotyto cunicularia hypogaea. Burrowing Owl. One or two were seen in the 

 colonies of prairie-dogs (Xynomys arizonoisis) , a few miles below the Huachucas. 



Geococcyx calif ornianus. Road-runner. Frequently seen in the foothills of 

 the Huachucas. Most of the birds observed were singularly tame and unsuspicious. 



Dryobates villosus hyloscopus. Cabanis Woodpecker. Sparingly distributed
