sides of the throat ; below dull whitish with a faint buffy wash on the 
chest and flanks ; upper mandible dusky, lower much paler, legs pale

Distribution.—The great plains region of North America, breeding 
from Saskatchewan to Nebraska and north-western Illinois and in 
eastern Colorado; south in winter to Lower California and over the 
Mexican plateau to the State of Oaxaca. 
In Colorado the Clay-coloured Sparrow appears to be confined to the 
eastern plains section of the State, where it is fairly common on migra- 
tion, and breeds, according to Aiken, commonly in El Paso and Fremont 
cos., a3 well as in the San Luis Valley. It reaches Colorado Springs in 
May, and is again seen in September, the extreme dates for El Paso co. 
in the Aiken collection being May 11th and September 28th. The only 
notice of its occurrence in the mountains is that of Kellogg, who pro- 
cured 4 single example in Estes Park on August 10th. Other records 
are: Lincoln co., May (Aiken), Pueblo (Beckham), Baca co., common 
after May 4th (Warren). 
Habits.—The Clay-coloured Sparrow is a characteristic 
bird of the great plains region, and is generally found 
about thickets and bush along river valleys ; it has much 
the same habits as the Chipping Sparrow, which it closely 
resembles, and with which it is often associated. I
