127. Western Chipplng-Sparrow ; Spizella socialis arizonct 

 Coues. 



Almost identical with the familiar chippy or hair bird of the 

 eastern states, of which it is a mere variety. Length, five inches or more. 

 Forehead black or blackish; crown bright rufous, distinctly contrasted 

 with neck and back ; back streaked brown, gray, and black ; breast plain 

 ashy, unstreaked. There is a line of white or grayish over the eye and 

 a fine black border below this. Song a uniform sustained trill. A 

 common summer resident both in the valleys and mountains, especially 

 in central and northern California. This bird must not be confounded 

 with the rufous-crowned sparrow (No. 133) with which it should be 

 compared. 



128. Brewer's Sparrow; Spizella hreweri Cass. 



An exceedingly plain little sparrow. Length of preceding or a 

 trifle less. No special markings anywhere. Above streaked grayish 

 brown and dark brown; below dirty white. An inhabitant of the sage- 

 brush plains of the interior valleys and mountains. 



129. Black-chinned Sparrow; Spizella atrogularis (Cab.). 

 Belonging to the chipping-sparrow group, and similar in size except 



for the long tail. Length, six inches. Head grayish; back rusty brown, 

 streaked with black; chin and upper throat black; breast grayish. In- 

 terior sage-brush regions of Southern California — Los Angeles, San 

 Bernardino and San Diego Counties. 



130. Slate-colored Junco ; "Snow-bird" ; /unco /il;ema/is (Linn.). 

 This is the familiar little "snow-bird" (not the snow bunting) of the 



eastern states. It is for the most part plain slate color, sharply contrasted 

 across the breast with the white of the under parts. The outer tail- 

 feathers are conspicuously white in contrast to the dark color of the 

 others. The typical eastern bird has been found in California only as a 

 rare straggler, but several race forms, differing only in a shade of color or 

 of size, occur in California. The Pacific Coast forms have the sides 

 tinged with pinkish buff, and the middle of the back more or less brown. 

 One of our commonest winter visitants from the north is the Oregon 

 Junco {J unco hyemalis oregonus Towns.). Sides of body dull pink, 

 and head and back not sharply different in color. A winter visitor in 

 the valleys of California, especially on the coast to San Francisco Bay. 



Thurber's Junco; Junco hyemalis thurberi Anthony. 



Distinguished from the Oregon junco by having almost no pinkish 

 on the flanks, and the head and throat black, sharply defined in contrast 

 to back. Sierra Nevada Mountains and deserts and southern coast 

 ranges of California.
