114. Pine Siskin; Pine Finch; Spinus pinus 

 (Wils.'). 



An undeveloped goldfinch in which the yellow is 

 just beginning to appear on the body and the 

 feathers of the wings and tail. Everywhere 

 streaked brownish and grayish ; base of tail and 

 edges of wing-feathers yellow. Breeds in the

115. English Sparrow; European House Sparrow; 

 Passer domes tic us Linn. 



The English sparrow was unfortunately introduced 

 into California some years since, and is rapidly 

 spreading. Any measures which will serve to 

 check its increase will be of benefit to our native 

 birds. Length about six inches. Top of head 

 gray; sides of head chestnut; back brown, 

 streaked with black ; lower parts dull grayish; 

 a conspicuous black patch on throat and upper 

 breast. Female with black patch wanting, and 

 with colors less bright and pure. Abundant in 

 towns and cities about San Francisco Bay, at 

 Stockton, Sacramento and other points in the 

 Sacramento Valley.

 ine us con finis Baird. 



An obsurely marked sparrow, streaked above and 

 below. The novice will be much puzzled with 

 many birds of this family with a general streaked 

 grayish and brownish coloration, whitish below. 

 The marks by which the vesper sparrow may be
