17. Centrocercus urophasianus Sw. Common. I put one 

 up near the brook and it flew upon the side of the hill and alighted 

 among the sage bushes. When I went after it I could not find it 

 and stood looking around, when it moved its head and attracted my 

 attention. It was lying flat on the ground within a few paces, but 

 its colors harmonized so well with the color of the ground on which 

 it was lying that if it had not moved I should have overlooked it. 



IV. Notes on Birds observed in the vicinity of Nevada City, CaL, 

 between August 15th and December 15th, 1872. 



This locality has an intermediate situation between the lofty 

 peaks and the foot-hills of the Sierra Nevadas, and is in the midst of 

 the gold mining region. My visit being in the last of the dry season, 

 when the vegetation is dried up by the hot sun, probably many of 

 the spring and early summer residents had gone farther down where 

 the farms are more numerous and less parched than the uncultivated 

 hills surrounding Nevada. 



In November, while collecting twenty miles farther down, we found 

 many species abundant which were rare at Nevada; among which 

 may be mentioned, Sturnella neglecta, Zonotrichia coronata, Glaucid- 

 ium californicum, which assembled in numbers around our camp fire 

 every night and serenaded us with their curious notes; also Loplwrtyx 

 californicus, Oreortyx pictus, and many others, were observed on the 

 cultivated flats which were rare at Nevada. 



turdim;. 



1. Turdus migratorius Linn. Robin. Common during Au- 

 gust and September. In October they became very abundant in 

 large flocks along the creeks. 



2. Turdus Swainsoni var. ustulatus Coues. Oregon 

 Thrush. Common but very shy. Found along the densely shaded 

 streams. When the rains began in November they came out of the 

 heavy timber into bushes along the outskirts of woods. 



3. Oreoscoptes montanus Baird. Mountain Mocking-bird. 

 Not common. Saw two pairs of them in October. They were prob- 

 ably migrating, as I did not see them again.
