Abundant and widely distributed. 1 found them on the lower Rio Grande, but more abundantly in the middle of the conti- 

 nent. Prefer habitually the stunted and sparse vegetation of the sand hills and dry plains to the cotton-wood groves and willow 

 thickets of the river valleys, where, indeed, they were never seen. They would certainly be very inconspicuous, as well from 

 their color and habits as from size, if it were not that the male occasionally perches himself on some dry stick or topmost branch 

 and pours forth a continuous strain of music- In some of the more barren regions, where the Creosote plant and stunted forms 

 of the mesquite constitute the only vegetation, they may be said to be the representatives of the feathered tribes. — (Clark.) 

 Sparrow-hke in its habits ; has a low note, and keeps in close attendance upon its mate, — (Couch.) 



Found on the hill sides adjacent to the Rio Grande and Corralitos rivers, feeding among the low bushes. It was quite wild; 

 flying very rapidly for a short distance, alightinj[j on a bush, and, immediately descending to the ground, would run oJf very 

 swiftly. Two or more generally observed together. — (Kennerly.)
