of the head, and another over the eye. The 

 breast is white, profusely streaked with dark 

 brown, the streaks forming a line down the sides 

 of the white throat. On the eastern slopes of 

 the Sierra Nevada Mountains a pale race, the 

 Mountain Song Sparrow, Meiospiza melodia 

 montana^ occurs, while in the interior valleys of 

 the State, west of the Sierras, Heermann's Song 

 Sparrow, Meiospiza melodia heermanniy is found. 

 Its chief characteristics are its dark color and its 

 robust bill. 



Samuel's Song Sparrow is the coast form, with 

 more slender bill, but such distinctions cannot 

 be made in the live bird. It is only by com- 

 parison of a large series in a museum that the 

 differences are apparent, and every shade of 

 intergradation between them can be shown. 

 The Rusty Song Sparrow is found along the 

 coast north of California, but migrates south in 

 winter to the northern parts of the State. It is 

 dark rusty in tone. 



Another race has been recently described from 

 Santa Barbara Island, which flies to the adjacent 

 mainland during the winter months. 



132. Lincoln's Sparrow; Meiospiza lincolni 

 (Aud.). 



This is another member of the song sparrow 

 group, but a distinct species. Size a trifle 

 smaller than a song sparrow. General style of 

 coloration similar, but a buff band on the breast 

 streaked with fine lines of black, in contrast to 

 the white of the remaining under parts, will 

 serve to distinguish it. Less common, and 

 generally found as a migrant or winter visitant
