8 NORTH AMERICAN FAUNA. [No. 7. 



The known range of the plumed quail (Oreortyx pietm plumiferus) was 

 carried eastward from the eastern slope of the Sierra Nevada to Mount 

 Magruder, Nevada, and to all the desert ranges of southern California 

 west of Death Valley. This valley apparently limits the distribution of 

 this bird on the east, as the species was nowhere seen in the Grapevine 

 or Charleston mountains, although both ranges are well timbered and 

 bear brush which might afford suitable food and shelter. 



Baird's woodpecker (Dryobates scalaris bairdi) was quite common 

 among the tree yuccas on the Mohave Desert at Hesperia, and its range 

 was extended northward to Yegas Valley, Nevada, and the valley of 

 the Santa Clara, in southwestern Utah, by Dr. Merriam. The vermilion 

 flycatcher also was secured in the same valley, though previously un- 

 known north of Fort Mohave, Ariz. The Texas nighthawk (Chordeiles 

 texensis) was found to be a common summer resident in all the valleys 

 east of the Sierra Nevada from Owens Valley, California, to St. George, 

 Utah, where Dr. Merriam secured the eggs. It was taken also in the 

 San Joaquin Valley, California, near Bakersfield. Scott's oriole (Icterus 

 parisorum) is another species whose range was carried northward from 

 a short distance above our southern border in California to about lati- 

 tude 38°, where it was common in places among the tree yuccas, and 

 also on the slopes of some of the desert ranges as high as the junipers 

 and pinons. Along the northern line of distribution it was found in 

 Nevada at the Queen mine in the White Mountains, at Mount Magru- 

 der, and in the Juniper Mountains, and in Utah in the Beaverdam Moun- 

 tains. Costa's humming bird (Galypte costce) was very common wher- 

 ever water occurred throughout the desert region, ranging northward 

 nearly to latitude 38°, and eastward to the Beaverdam Mountains, 

 Utah. Its nest was frequently found in the low bushes and cactuses on 

 the hillsides near springs and streams. 



The discovery that the gray-crowned finch (Leucosticte tephrocotis) 

 breeds in the southern Sierra and in the White Mountains is especially 

 interesting both because its breeding range was previously unknown, 

 and because no species of the genus had been recorded from the Sierra 

 Nevada south of about latitude 40°, while the present species was com- 

 mon nearly to the 36th parallel. 



Most satisfactory results were accomplished in working out the dis- 

 tribution of Thurber's junco (Junco Ivy emails thurberi), a recently de- 

 scribed race whose range was not definitely known. In the Sierra 

 Nevada it was common from the Yosemite Valley, the most northern 

 point visited by any member of the expedition, to the southern end of 

 the range, and in the desert ranges eastward to the Grapevine and 

 Charleston mountains, where its place was occupied, in winter at least, 

 by its more eastern representative, Shufeldt's junco. The little black- 

 chinned sparrow (Spizella atrigularis) was found to be not an uncom- 

 mon summer resident on the slopes of several of the desert ranges and 

 also on the east slope of the Sierra Nevada as far north as Independ-
