May, 1908 SOME FALL MIGRATION NOTES FROM ARIZONA 113 many flocks were seen, evidently migrating, flying in a southerly direction along the base of the Huachucas. Carpodacus cassini. Cassin Purple Finch. Arrived in the Huachucas on November 5, when I secured an adult male at the summit of the range. My latest date for this species in the spring is May 11 (1903). Carpodacus mexicanus frontalis. House Finch. Seen on several occasions near the mouth of Miller Canyon, in October. In my experience it is not a com- mon species in this region at any time. Astragalinus psaltria hesperophilus. Green-backed Goldfinch. Not seen in the Rincons,.but fairly common in the foothill region of the Huachucas early in 'October. They disappeared before the end of the month. Spinus pinus. Pine Siskin. Fairly common in the pine region of the Huachucas, from 8,500 feet upwards, during the whole of our stay. Not observed in the Rincons. Passer domesticus. House Sparrow. A number of "English" Sparrows were observed in the streets of the town of Benson. The last time I visited the town, 'in June, 1903, they had not yet reached it. Calcarius ornatus. Chestnut-collared Longspur. An abundant nilgrant on the plains below the Huachucas. All through the month of October they wer? observed passing overhead, flock after flock, but comparatively few were seen to alight. Pocecetes gramineus confinis. Western Vesper Sparrow. Quite common on the plains below the Huachucas but not seen elsewhere. Passerculus sandwichensis alaudinus. Western Savanna Sparrow. There were one or two fields near the base of the Huachucas, where the ranchers had at- tempted to raise grain, and in these enclosures I found a number of Savanna Spar- rows. They were not seen elsewhere. Centronyx bairdi. Baird Sparrow. I had previously found this species quite abundant in the plains below the Huachucas in the spring of the year, but on this occasion, after much careful search and hard tramping, I was able to secure but two specimens, both taken on October 24, one an immature male, the other a high plumaged old female. Zonotrichia leucophrys gainbell. Intermediate Sparrow. Fairly common in the foothills of the Huachuc?s during October. ?7onolricg?'a [eucopgrys, in my ex- perience more abundant than ?rambe[i in this region in the ?pring, was not ?een at all. Spizella socialis arizona. ?. Western Chipping Sparrow. Exceedingly abund- ant, both in the Rincons and in the foothill region of the Huachucas. Spizella breweri. Brewer Sparrow. A single specimen was secured on the Huachuca Plains on October 28. Junco oreganus shufeldti. Shufeldt Junco. Arrived in the Huachucas on October 18, and became fairly abundant a few days later. But very few adult males were seen. Junco mearnsi. Pink-sided Junco. Not at all abundant; first seen on October 18. My latest date for this species in the spring in the Huachucas is April 15 (1903). Junco caniceps. Gray-headed Junco. Arrived on October 29 and became quite abundant shortly afterward. The latest date at which I have taken this species in this region in the spring is May 2 (1896). Junco ph?eonotus palliatus. Arizona Junco. This species was not observed in the parts of the Rincon Mountains we visited, but in the Huachucas it was, as usual, exceedingly abundant from 5500 feet upward. An old female shot on
