BLACK-THROATED SPARROW. 
573. Amphispiza bilineata. 5% inches. 
These little Sparrows are entirely unlike any other 
North American species. They are found in the south- 
western deserts, where they are not uncommon in cer- 
tain localities, being found in mesquite or chaparral 
brush. 
Note.—An ordinary Sparrow chip; song, a rich me- 
tallie ‘*zip-zip-zip-zee-zee-zee,” the first three ascending, 
the second three notes descending. 
Nest.—In bushes or cacti at low elevations; eggs 
plain bluish white (.70x .50). 
Range.—From Texas north to Kansas in summer. A 
paler sub-species, the Desert Sparrow (deserticola), is 
found westward to southern California. 
SAGE SPARROW. 
574.1 Amphispiza nevadensis. 6%4 inches. 
These birds are found in arid regions, frequenting the 
sage brush that is found in the Great Basin region, from 
western Texas to California.
