Fig. 441. Rufous-winged 
Sparrow. 
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 
brown; throat bordered by black stripe ; sides 
of head and neck and under parts pale buffy or 
brownish. Young: like adult, but upper parts 
dull brownish, streaked; under parts dingy 
buff, chest and sides streaked. Male: length 
(skins) 5.00-5.55, wing 2.20-2.40, tail 2.25- 
2.65, bill .41-.50. Female: length (skins) 
5.00-5.20, wing 2.18-2.30, tail 2.32-2.60, bill 
.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 Crafton 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.
