being- September 12. It was not uncommon along the Gila River, where 

 it usually kept in the tall cottonwoods. In 1874, it was again met with by 

 Dr. Rothrock and myself at Mount Graham, and under precisely the same 

 circumstances as the preceding species. They were, however, here quite 

 rare as compared with solitarius ; but, near Camp Crittenden, the last few 

 days of August, quite a number were seen among the deciduous trees. 

 Their seeming preference for the deciduous over the coniferous timber is the 

 only point wherein their habits seem to differ from those of the Solitary Vireo.

This is a common bird through the Middle Region, entirely replacing 

 there in summer the Solitary Vireo. In choice of habitat, it is somewhat 

 variable, but is more usually met with among the pines ; finding its limit at 

 an altitude of about 10,000 feet, In' the migratory season, however, it 

 scatters over the country generally, finding in the deciduous trees of the
