July, 1915 WOODPECKERS OF THE ARIZONA LOWLANDS 163 They are not close sitters, and usually leave the nest before the tree is reached or the ladder placed against the trunk. As soon as an intruder's foot- steps become audible the landlady pokes her head from the entrance, and soon after departs, never giving opportunity ?or capturing her on the nest. De- serted flicker nest holes are made use of by several other birds. In these holes I have often found Sparrow-hawks and Sagua?o Screech Owls. Once a Ben- dire Thrasher made her nest in one with a crack in one side that let in light enough for her. In a partly excavated hole I found the nest of a Western Kingbird, and in another the nest of a ]louse Finch. Occasionally the Cactus Wren builds in the deserted hole. In one Saguaro I found occupied nests of the Gilded Flicker, Gila Woodpecker, and Ash-throated Flycatcher. A Cactus Wren was in an ironwood at the base of the cactus, and, beyond reach of the ladder, were holes giving signs of occupancy by owls. I have never secured any of these flickers in the red phase of plumage described by Mr. Grinnell (University of California, Publications in Zoology, vol. 12, 1914, pp. 136-137) though I have noticed a few that seemed deeper in color than others.

PIERCE THESE NOTES are taken from a list of a hundred odd species noted in the I vicinity of Big Bear Lake and Bluff Lake in the San Bernardino Moun- tains, southern California, between September 15 and 23, 1914. Only those species are included which for one reason or another may be deemed worthy of comment. Colymbus ni.gricollis caiifornicus. Eared Grebe. Common on Bear Lake, where, much to our surprise, downy young were not uncommon at this late date. A series of young taken September 17 graded all the Way from apparently newly hatched chicks to fully grown .birds in complete fall plumage. While the majority of adults were still in full, though rather worn, breeding dress two were taken which in life were not dis- tlngulshable from fall juvenals. Porzana carolina. Sora. One was flushed from the grass at the edge of Big Bear Lake, September 17. Though recorded previously on but two occasions Sofas are prob- ably not uncommon migrants through the locality. It is doubtful if they breed there. Orsortyx picta plumifera. Plumed Quail. Unexpectedly rare, in fact apparently absent from the region under consideration. The only evidence of the species found were some feathers in the trail at Clark's Ranch (elevation 5000 feet), in the Santa Ana Canyon. Circus hudsonlus. Marsh Hawk. A female seen beating over the lake, September 22. Falco mexicanus. Prairie Falcon. A female of the year taken at Big Bear Lake on September 17, and another (Judged to be a male) seen in the same locality Septem- ber 20. Xenopicus albolarvatus. White-headed Woodpecker. But 'very few of the speci- mens taken had completed the fall molt; the majority still retained the worn summer feathers on the belly and center of the breast. As this condition was common to both adults and birds cf the year it seems not improbable that the fall molt of both occurs at approximately the same time. Those which had complete new plumage were Juve- nals, very likely of early broods. White-headed Woodpeckers were often observed to drink at a small stream near our camp at Bear Lake, where a pine sapling grew from the edge of a small pool. On
