88 ZOOLOGY 



ZONOTRICHIA AUROCAPILLA. 



The Yellow-crowned Finch. 

 Abundant about San Francisco in winter. 



ZONOTRICHIA GRAMINEA. 



The Bay-winged Finch. 

 Common in the Sacramento valley, California. 



SPIZELLA BREWERI. 

 Common in the Sacramento valley. 



SPIZELLA SOCIALIS. 

 The Chipping Sparrow. 

 We saw this familiar sparrow occasionally in the Sacramento valley. 



STRUTHUS OREGONUS. 

 The Western Snow Bird. 



This bird we found very common in northern California and Oregon in summer, and about 

 San Francisco in winter. In plumage and habits it so closely resembles its eastern representa 

 tive as to lead me, for a long time, to consider them identical. The lonely valleys of the 

 Cascade mountains contain large numbers of this little bird, having apparently the same habits 

 as the eastern species. 



CARPODACUS PURPUREUS. 



The Purple Finch. 

 Common throughout California and Oregon. 



CARPODACUS FRONTALIS. 



Purple House Finch. 

 Common in the valleys of California. 



OTOCORIS ALPESTRIS. 

 Sky Lark. 



Very abundant in all the open country of California and Oregon. On the prairies of the 

 Sacramento valley and of the Des Chutes basin, the shore larks, which rise before the traveller 

 at every step and fill the air with their cheerful chirpings, recall the sky lark which so abounds 

 on the moors and plains of Europe, and, by their numbers and their ceaseless twitter, give life 

 to scenes as monotonous as the prairies of the west. 



GUIRACA CGERULEA. 



The Blue Grosbeck. 

 This pretty and musical little bird we found only on Pit river, in northern California.
