126., Black-chinned Sparrow; Spizella atrigularis 

 (Cab.). 



Belonging to the chipping sparrow group, and sim- 

 ilar 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. Interior sage-brush re- 

 gions of southern California — Los Angeles, San

127. Slate-colored Junco; "Snow-bird;" Junco 

 hy em alls (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 con- 

 trasted across the breast with the white of the 

 under parts. The outer tail-feathers are con- 

 spicuously 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 

 Junco hyemahs oregonus (Towns.). Sides of 

 body dull pink, and head and back not sharply 

 different in color. A winter visitor in the val- 

 leys of California. 



Thurber's Junco; "Junco hyemalis thurberi An- 

 thony. 



Distinguished from the Oregon junco by having 

 almost no pinkish on the flanks, and the head
