PASSERES: Perching Birds 



SAGE SPARROW 



(574.1. Amphispiza nevadensis nevadensis) 6 in. 



Like the Bell Sparrow, but with back narrowly streaked, and 

 black stripe on side of throat less definite, usually not con- 

 tinuous. 



A persistent and pleasing singer in spring. 



CALIFORNIA SAGE SPARROW 



(574. Ib. Amphispiza nevadensis canescens) 6 in. 

 Differs from the Sage Sparrow proper in grayer color and 

 slightly smaller size. Like it in habits. Indistinguishable in the 

 field, where their winter ranges overlap. 



CASSIN SPARROW 



(578. Peucaea cassini) 6 in. 



Upper parts a soft mixture of dusky and brown, gray-edged; 

 crown finely streaked; whitish below, sides faintly washed or 

 streaked with brown. 



Absence of distinctive markings visible in the field is best 

 "field mark" of the species. It is a light-colored, grayish bird. 

 (Compare Botteri Sparrow.) 



RUFOUS-CROWNED SPARROW 



(580. Aimophila ruficeps ruficeps) 5 in. 



Back a rich mixture of rich brown and gray; crown rufous; 

 light olive-brown below, lighter on throat; sides of throat black- 

 striped. 



A dull-colored, inconspicuous bird, with a lively, jingling 

 song somewhat like that of the Lazuli Bunting.
