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 for 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 Saguaro 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 House Pinch. 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. Grinned (Fniversity of 
California, Publications in Zoology, vol. 12, 1914, pp. 136-137) though I have 
noticed a few that seemed deeper in color than others.

FURTHER NOTES FROM THE SAN BERNARDINO MOUNTAINS 
By ADRIAAN VAN ROSSEM and WRIGHT M. PIERCE 
T HESE NOTES are taken from a list of a hundred odd species noted in the 
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 nigricollis californicus. 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- 
tinguishable 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 Soras are prob- 
ably not uncommon migrants through the locality. It is doubtful if they breed there. 
Oreortyx 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 hudsonius. Marsh Hawk. A female seen beating over the lake, September 22. 
Faico 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
