Amphispiza bilineata deserticola Ridgway 

 Desert Black-throated Sparrow 



A common species on the desert foothills; one of the few 

 birds that is even fairly abundant od the hot, dry mesas forming 

 its habitat. Seen scattered through the brush at Dos Palmos, and 

 in Palm Canon from the tloor of the desert at the canon mouth 

 up to about 3000 feet. In San Gorgonio Pass it was one of the 

 characteristic birds at Whitewater. Snow Creek, Cabezon. and 

 Banning. 



A nest containing two eggs ( no. 77 ) was found near the brink 

 of Deep Canon, June 1. It was in a little gully, about a quar- 

 ter of a mile from water, and placed in a clump of Dalea 

 johnsonii, about one foot from the ground. It was loosely fas- 

 tened among the forking branches, being held in place more 

 by the general thorniness of the shrub than by any evident fore- 

 thought in its construction. The material of the nest is mostly 

 gray, weathered grass, and some fine weed stems. The parent 

 bird slipped quietly off the nest, flew to some distance, and did 

 not return. 



This may have been a second set. full-grown juvenals being- 

 seen on the same date. As young birds at about the same stage 

 of development were secured. in this locality late in the sum- 

 mer. August 23 to 27, the nesting season appears to be rather 

 protracted. Adults taken dining the last week in August had 

 nearly finished the annual molt. 



The species was encountered at one place west of the moun- 

 tains, a single bird being seen at Vallevista, September 4. 



Twenty-six specimens were preserved: Snow Creek, two i nos. 

 2070. 2166), Cabezon, seven (nos. 1628-1633, 2125), Banning,
