JRemarks. — The claj^-colored and the Brewer sparrow both have 

 streaked npper parts, but the clay-colored has a median crown stripe and 

 plain gray hind neck, while the Brewer is uniformly streaked on head, 

 neck, and back. 



Distribution. — Breeds in Transition and Canadian zone from the Sas- 

 katchewan plains south to Iowa and Nebraska and from Illinois west to 

 western Montana ; migrates south to Lower California and southern end of 

 Mexican tablelands. 



Nest. — In bushes in open situations. Eggs : usually 4, light greenish 

 blue, speckled chiefly around the larger end with brown. 



The clay-colored sparrow is said to be almost exclusively terres- 

 trial, though during the nesting season the males sing from the tops 

 of bushes almost continually. The song Coues gives as three notes 

 and a slight trill. Along the Red River in Dakota, he says, they 

 nest in "open low underbrush by the river side and among the 

 innumerable scrub- willow copses of the valley."

Distribution. — Breeds in Transition zone „. 



sagebrush from British Columbia south to '^' 



southern Arizona, and from western Nebraska and western Texas to the 

 Pacific coast ; south in winter along the western border of the Mexican 

 tablelands. 



Nest. — In .sagebrush, made <»f fine grass stems and leaves, lined with 

 long horsehairs. Eggs : usually 4. and generally like those of the clay- 

 colored sparrow, but more distinctly marked. 



The Brewer sparrow, known locally as the sagebru.sh chipiM'e, is 

 marked down as an 'arid transition ' species, and, true to his zonal 

 colors, if any arid transition sagebru.sh strays to the sunny side of a 

 high mountain ridge he will appear there with it, though his normal 

 home is in the bottom of a desert. We once found liim singing at 

 8400 feet on the snowy crest of the Sierra, but on the sunny slope 

 below was the inevitable sage.
