May, 1908 SOME FALL MIGRATION NOTES FROM ARIZONA 115 mouth of Miller Canyon on November 4, was, strangely enough, the only one of the species observed during the trip. ' Lanius lud0vicianus excubit0rides. White-rumped Shrike. Fairly COl:nmon in the foothill region of the Huachucas, and on the plains below. An immature male taken on October 9, had not quite finished the mottit. Vireo hutt0ni stephensi. Stephens Vireo. Observed only in the Huachucas, where two or three were seen in the live oaks, all below 5500 feet. Dendr0ica audub0ni. Audubon Warbler. Several were observed on my first visit to the summit of the Huachucas, on October 3, and they were later found quite abundantly in the pines, but not in the lower parts of the mountains. Var. ?dgrzfrons had apparently left the mountains before we arrived. Dendr0ica nigrescens. Black-throated Gray Warbler. A single bird seen at the mouth of Miller Canyon on October 31 was the only one observed on the trip. My earliest date of arrival for the species in this region is March 31 (1903). Dendr0ica t0wnsendi. Townsend Warbler. One was observed at the summit of the Huachucas, about 9000 feet, on October 3. The earliest fall arrival I have record of was seen on August 19 (1902). 0p0r0rnis t01miei. Tolmie Warbler. One or two were noted near the summit of the Huachucas on October 3. My earliest fall record for this region is August 21 (1902). Wilsonia 1m?illa pileolam. Pileolated Warbler. One or two were seen in the oak belt of the Huachucas during the first week in October. Set0phaga picta. Painted Redstart. A single bird seen near the mouth of Miller Canyon on October 5 was the only one observed.' The earliest date at which I have seen the species in the Huachucas is March 15 (1903). Antbus pensilvanicus. American Pipit. A few were seen in some flocks of shore larks, on the plains, a mile or two below the Huachucas, on October 28. ' It does not appear to be a very common species in southern Arizona, and this is the only occasion on which I have seen it in this region. Toxostoma rufum. Brown Thrasher. It was one of the surprises of the trip when I secured a male bird of this species, on October 5, near the mouth of Miller Canyon, in the Huachucas, where it was feeding in company with several Palmer Thrashers. I believe that this is the first time the species has been recorded from Arizona, which is far beyond the normal limits of the race. Toxostoma curvirostre palmeri. Palmer Thrasher. In the lower parts of the Huachucas, up to about 5000 feet, this species was quite common, much more so than I have ever found it in the spring. It was not observed in the Rincons, though there is no apparent reason why it should not occur there. Heleodytes brunneicapillus couesi. Cactus Wren. A few were seen in the foothills of the Huachucas, but they were not at all abundant. Salpinctes obsoletus. Rock Wren. Fairly common along the base of the Huachucas, and very abundant on the rough, rock-strewn hills of the Rincon Mountains. Catherpes mexicanus c0nspersu. s. Canyon Wren. Seen both in the Huachu- cas and in the Rincon Mountains, but not common in either range.. Thry0manes bewickii erem0philus. Desert Wren. Found both in the Rincons and in the Huachucas. In the latter range they were seen up to about 6000 feet, the same as during the summer months, and in about equal numbers. They are undoubtedly resident. Troglodytes aedon parkmanfl. Parkman Wren. A single bird remained for
