streams a welcome place of resort as well as an abundance of suitable 

 insect food. In habits generally, and song, it is quite identical with the Sol- 

 itary Vireo. During the season of 1874, many specimens were secured in 

 Colorado and New Mexico by Mr. C. E. Aiken, and in the different locali- 

 ties it was everywhere numerous. 



A nest found by Mr. C. E. Aiken in El Paso County, Colorado, and 

 by him kindly presented to me, exhibits but little difference when compared 

 with nests of the true solitarhis taken in New England. It is composed of 

 soft, cottony substances, bound externally with strips of bark and other 

 fibrous material, with a lining of fine grasses. The eggs are pure white, 

 spotted chiefly at the larger end with reddish-brown. 



A specimen, taken September 3, at Camp Apache, Ariz., is intermediate 

 in coloration between solitarhis and plunibeus, showing very clearly the rela- 

 tionship of the two. A strong greenish tinge pervades the back, and is also 

 very decided on the sides and flanks.

This little Vireo appeared to be rather common along the Gila River, 

 inhabiting the dense thickets along the banks. At this season, the middle 

 of September, its quaint song was heard during most of the day, but more
