THE CONDOR yoh. X 



October 3, is still in the midst of the moult, and ragged-looking birds were ob- 

 served up to about the middle of the month. Young birds taken the end of 

 October are, in every respect, absolutely indistinguishable from the adults. 



Aimophila cassini. Cassin Sparrow. Several were seen in some fields of tall 

 grass near the mouth of Miller Canyon. It was almost impossible to secure speci- 

 mens, from their habit of lying until almost trodden upon, and then darting off in 

 zig-zag flight through the grass, to repeat the performance when followed up. An 

 immature female shot on October 25 is in the midst of the moult, covered with 

 pin feathers, and others seen during the first week in November were quite as 

 ragged in appearance. 



Aimophila ruficeps scotti. Scott Rock Sparrow. Fairly abundant on the rocky 

 hills of the Rincon Mountains. An adult male secured on September 25, and 

 others seen at the same time, were in the midst of the moult. A few were seen in 

 the Huachucas. 



Melospiza lincolni. Lincoln Sparrow. A single bird was seen in the Huachu- 

 cas on October 11. 



Pipilo maculatus montanus. Mountain Towhee. A few were seen in the 

 Rincons, while in the Huachucas they were abundant from the summit almost, but 

 not quite, to the base of the range. Immature birds taken the last week in Sep- 

 tember and during October are not appreciably different from adults. 



Pipilo fuscus mesoleucus. Canyon Towhee. I have never in the spring or 

 summer seen this species as abundant in the Huachucas as it was throughout the 

 foothill region this fall. Early in October all the birds seen were moulting, and 

 very ragged in appearence, and specimens with pin feathers on them were taken as 

 late as October 22. 



Oreospiza chlorura. Green-tailed Towhee. This species was seen in abund- 

 ance in the chaparral country between Benson and the Rincon Mountains, on Sep- 

 tember 22, evidently migrating. It was also met with in the Rincons, and later 

 a few were seen in the foothills of the Huachucas, the last observed being on 

 October 30. My earliest fall date for the species in the latter range is Septem- 

 ber 1 (1902). 



Zamelodia melanocephala. Black-headed Grosbeak. A very few were seen in 

 the Huachucas during the first two weeks in October, the last observed being a 

 female secured October 16. My earliest date for the arrival of the species in this 

 region is April 20 (1902). 



Calamospiza melanocorys. Lark Bunting. Seen in abundance along the San 

 Pedro River between Fairbanks and Hereford on September 30. It is rather sin- 

 gular that the species was not observed anywhere else. 



Piranga hepatica. Hepatic Tanager. A very few were seen at various times in 

 the lower parts of the Huachucas, below 5500 feet, the last observed being on 

 October 25. My earliest record for the arrival of this species in the Huachucas 

 in the spring is April 11 (1902). An adult male taken October 1 had nearly com- 

 pleted the moult. 



Piranga rubra cooperi. Cooper Tanager. An immature female taken in the 

 Rincon Mountains on September 23, 1907, was the only one of the species observed. 

 Tachycineta thalassina lepida. Northern Violet-green Swallow. Seen at 

 various times during the whole of our stay in the mountains. 



Ampelis cedrorum. Cedar Waxwing. Several small flocks were seen in the 

 Huachucas during the first week in October. In my experience this is anything 

 but a common species in southern Arizona. 



Phainopepla nitens. Phainopepla. A single bird, an adult male, seen at the
