This, the western race of the Savanna Sparrow, replaces that bird in the 

 Middle Region, and extends southward through Arizona and New Mexico, 

 having been found by us a summer resident as far as the border line of 

 Mexico. It is everywhere common, frequenting with indifference the moist 

 meadowy lands in the vicinity of streams and the dry arid plains. In 

 Colorado, Mr. Aiken secured specimens from various localities, and found it 

 numerous. At Denver, it was common the 1st of May, having apparently 

 arrived long before ; but, from the 1st to the 12th, a continual increase in 

 numbers was noted.
