of the breeding season a complete and general diffusion of this species over 

 the country to the southward of its summer habitat. It winters in great 

 numbers in Southern Utah, and in Colorado well up into the middle of the 

 Territory ; though Mr. Aiken informs me that in El Paso County compara- 

 tively few of this species remain during the winter, the greater proportion 

 passing on farther to the south. As a winter resident in Arizona and New 

 Mexico, it is by far the most numerously represented of the genus, and is 

 found everywhere, low down in the mountains, in the foot hills, and along 

 the streams of the valleys and plains. I have never found it in the mount- 

 ains of this region in summer, and am quite positive that none remain here 

 to breed.
