In the foothills of the Santa Catalina Mountains, Arizona, Mr. 

 Scott found small flocks of the rufous-winged sparrows from an alti- 

 tude of 3000 to 4500 feet. They were sometimes associated with 

 the chipping sparrows, whose habits are similar.

Adults. — Crown chiefly reddish brown; rest of upper parts grayish or 

 grayish brown, broadly streaked with reddish 

 broivn ; throat bordered by black stripe ; sides

 Fig. 442. .43-.50. 



Remarks. — The prevailing dull reddish 

 brown of the upper parts, together with the size, marks the rufous-crowned 

 sparrow. 



Distribution. — From northern California — latitude 40° — south along 

 the Pacific coast to northern Lower California. 



Nest. — On or near the ground, made of grasses, lined with stems and 

 sometimes a few hairs. Eggs : 3 to 5, plain white or bluish white. 



In Los Angeles County, Mr. Grinnell says, the rufous-crowned is 

 tolerably common locally in the foothills throughout the year, but is 

 most abundant in April. In the Grafton Hills, where Mr. Williams 

 found it nesting, it was very shy and rarely seen, the brooding bird 

 gliding from her nest and dodging around the tufts of grass until 

 hidden behind a bush.
