This peculiar flycatcher appears to be a summer resident of the 

 Chiricahua Mountains, Southern Arizona, where I obtained a pair of old 

 birds, together with three young, August 24. These, though indistinguish- 

 able in size and perfection of plumage from the adult pair, were still the 

 objects of their solicitous care, and were dependent upon them for food. 

 Indeed, their presence might have remained unnoticed by me, had I not 

 been greeted, as I entered the mouth of one of the deep, narrow canons 

 intersecting the mountains in every direction, by the shrill notes and angry cries 

 of the old birds, who hovered in the air at a short distance, or flew restlessly 

 from tree to tree, endeavoring to distract my attention from the young, till 

 taking the alarm, they flew over into an adjoining ravine, where soon after 

 I found the whole family assembled, the old birds having immediately 

 rejoined their charges. The following day, Dr. Rothrock, while out botaniz- 

 ing, saw what he supposed to be a second family of six or seven of these 

 birds, so that the occurrence of the species here is probably to be regarded 

 as by no means accidental. This region may form its northern limit.
