A single specimen was taken at old Camp Goochvin, Ariz., and occa- 

 sionally an individual was met with among the mesquite trees along the 

 Gila River. The habits, so far as observed, seemed to resemble those of 

 the Titmice, as does also its great variety of notes. 



In 1874, I met with the species but once, at Camp Lowell, Ariz., in 

 September. This seeming rarity of the species in a region well adapted to its 

 habits was probably due to the lateness of the season at which our visits to 

 Southern Arizona have been made ; it probably having departed to a more 

 congenial winter habitat farther south.
