190 THE CONDOR Vol. XXVI 



Thryomanes bewicki eremophilus. Desert Wren. One seen September 19, and 

 one collected September 29 (both in junipers) were all observed. 



Troglodytes aedon parkmani. Western House Wren. One seen at the lower 

 edge of the yellow pines September 8. Not otherwise observed. 



Certhia familiaris montana. Rocky Mountain Creeper. One collected October 

 27 on the northeast slope of San Francisco Mountain at about 8000 feet altitude; the 

 only one seen. 



Sitta carolinensis nelsoni. Rocky Mountain Nuthatch. In small numbers at the 

 lower edge of the yellow pines, and occasionally in the piiions and junipers. 



Sitta canadensis. Red-breasted Nuthatch. One bird seen October 17 at about 

 8000 feet altitude on the northeast slope of San Francisco Mountain. Not otherwise 

 observed. 



Sitta pygmaea pygmaea. Pygmy Nuthatch. Fairly abundant in the yellow pine 

 belt, but not once encountered in the pinons and junipers just below. 



Baeolophus inornatus griseus. Gray Titmouse. Closely restricted to the pinon- 

 juniper belt. Not abundant anywhere; at the most perhaps six or eight might be seen 

 in a forenoon. 



Penthestes gambeli gambeli. Mountain Chickadee. Fairly common in the lower 

 part of the yellow pine forest and throughout the pinon-juniper belt. On October 16 

 my eye happened to be caught by a single Mountain Chickadee coming straight down 

 from high overhead, to alight in an isolated juniper. This seems clear evidence of 

 migration. 



Psaltriparus plumbeus. Lead-colored Bush-tit. Not at all common. Small flocks 

 were encountered at long intervals, near the upper limit of pinon and juniper and in 

 the lower portion of the yellow pines. 



Regulus satrapa olivaceus. Western Golden-crowned Kinglet. In Woodhouse's 

 report on the natural history of Sitgreaves' Expedition down the Zuni and Colorado 

 Rivers (1853), there is casual reference to the occurrence of this species on San Fran- 

 cisco Mountain (p. 68, under Parus montanus). The date of observation would have 

 been somewhere from October 9 to 22. There was no more definite record for Arizona 

 until Cooke (Auk, 1914, p. 404) reported a specimen taken by C. Birdseye, September 

 14, 1908, in the White Mountains. On October 24, in a clump of Douglas fir near the 

 upper edge of the yellow pines, at 7500 feet altitude on the northeast slope of San 

 Francisco Mountain, I heard the lisping note of the Golden-crowned Kinglet. I col- 

 lected one bird and heard one or two others. It was interesting thus to be able to 

 corroborate Woodhouse's observation of many years before, and at a point that must 

 have been within a few miles of where he crossed the northern shoulder of the 

 mountain. 



Regulus calendula calendula. Rul»y-crowned Kinglet. Several seen at high alti- 

 tudes on San Francisco Mountain September 14, two at Deadman Flat September 29, 

 and one at 8000 feet altitude on San Francisco Mountain October 27. 



Polioptila caerulea obscura. Western Gnatcatcher. Two seen at Deadman Flat 

 September 6. Not otherwise observed. 



Myadestes townsendi. Townsend Solitaire. Appeared in the pinon-juniper belt 

 September 28, when two were seen. By the middle of October they were abundant, 

 and remained so through the month. On October 11 about sixty Townsend Solitaires 

 were in sight at once about a small "tank". 



Planesticus migratorius propinquus. Western Robin. Abundant in the juniper 

 thickets, where they were feeding on the berries, the latter part of September and 

 throughout October. 



Sialia mexicana bairdi. Chestnut-backed Bluebird. Seen in some numbers in 

 the yellow pine region near Flagstaff upon our arrival there, September 3. A few 

 days later they appeared at Deadman Flat, and in increasing numbers during Sep- 

 tember and throughout October. 



Sialia currucoides. Mountain Bluebird. As with S. m. bairdi this species was 

 seen early in September in the yellow pine belt, and a little later at Deadman Flat. 

 During the latter part of October both species of bluebirds were extremely abundant 

 in the juniper thickets. On October 25, at Dove Tank, there was a solid mass of 

 bluebirds congregated at the water's edge that I estimated to contain two hundred or 

 more individuals, a brilliant blue margin bordering one entire side of the tank. About 

 two-thirds of the fiock were currucoides. 



Berkeley, California, December 20, 1923.
