THE CONDOR 
voi„ Vn 
ern Arizona, where I have never seen them in anything like the large numbers 
occurring in California. 
Junco p. palliatus. Arizona Junco. A few seen, none below 6000 feet. Some 
juveniles were secured. 
Amphispiza b. deserticola. Black-throated Sparrow. Very common every- 
where along the foothills and out on the mesa. Full grown juveniles were secured. 
Aimophila r. scotti. Scott Sparrow. Fairly common on the rock-strewm 
foothills. 
Pipilo m. megalonyx. Spurred Towhee. Quite common; seen mostly along 
the canyons. 
Pipilo f. mesoleucus. Canyon Towhee. Fairly common in the lower parts of 
the mountains. I found one nest containing young just hatched, but full grown 
juveniles were also seen. 
Zamelodia melanocephala. Black-headed Grosbeak. Seen in the higher parts 
of the range, but not very abundantly. Some birds were also seen in the lower 
foothills, where they certainly were not breeding. 
Piranga hepatica. Hepatic Tanager. A few seen in the higher parts of the 
mountains. Adults and juveniles were secured. 
Piranga r. cooperi. Cooper Tanager. Fairly common, most of the birds seen 
being in the deep, wooded, ravines below the mountains. I found myself continu- 
ally comparing the avifauna of the Santa Ritas with that of the Huachuca Moun- 
tains, where I had been collecting earlier in the season, and was surprised at find- 
ing many species breeding in the one range and not in the other, though the 
mountains present much the same general appearance, and at the nearest point 
cannot be much over twenty miles apart. The Cooper tanager, though an exceed- 
ingly rare migrant in the Huachucas, was breeding quite commonly in the Santa 
Ritas, and it was the same with many other species, mostly those generally found 
in the lowlands. 
Phainopepla nitens. Phainopepla. One of the commonest birds in the lower 
parts of the mountains, where both adults and juveniles were seen. This is an- 
other species that I have not known to breed in the Huachucas. 
Lanius 1 . excubitorides. White-rumped Shrike. Not seen in the canyons but 
frequently met with out on the mesa. On June 21 I found a nest with five eggs in 
a scraggly little mesquite bush, perfectly unsheltered and unhidden. As I exam- 
ined the eggs, both birds sat on the bush, almost within arm’s reach, with mouths 
open, suffering from the heat too much to care what happened. The sun was blaz- 
ing down so fiercely that had the nest not been low enough down to see into, I 
should certainly not have investigated its contents, even had it been a much great- 
er rarity; and as I did not care for the eggs, I sat in the shade of the brush for a 
moment, to see the female slip onto the nest immediately. 
Vireo g. swainsoni. Western Warbling Vireo. On June 23 Mr. Stephens se- 
cured an adult female of this species. On dissection it did not have any appear- 
ance of being a breeding bird: and as I have never found the species breeding any 
where in southern Arizona, I believe that this was nothing more than a straggler, 
which, for some reason, had failed to go to its breeding grounds. 
Vireo s. plumbeus. Plumbeous Vireo. Seen on various occasions in the high- 
er parts of the mountains. 
Vireo h. stephensi. Stephens Vireo. Seen in the oaks of the lower parts of 
the range. Although in California huttoni is found quite commonly in the willow 
regions of the lowlands, its Arizona prototype, stephensi appears to be a bird of the 
mountains exclusively, and I have never observed it anywhere in the lower valleys.
