Apparently a very rare species, as it was met with but on two occa- 

 sions. At Inscription Rock, N. Mex., July 24, 1 observed a pair of old birds 

 feeding' the young'. These latter were nearly full fledged, and had evidently 

 been raised in the immediate vicinity. In September, a single immature bird 

 was taken near Camp Apache, Ariz., on a small brush lined stream in a heavy 

 pine forest. Judging' from the individuals seen, their habits differ in no note- 

 Avorthy respect from those of the small flycatchers generally. The species 

 was first described and introduced into our fauna by Dr. Coues, who gives 

 it as a rare summer resident at Fort Whipple, Ariz. 



During the past season, I saw several individuals of this species, but not 

 till well down into the southern part of Arizona. I am inchned to think 

 that it will not be found to occur much, if any, north of the thirty-foui-th 

 parallel, and that south of this it is a regular summer resident, though 

 certainly very far from common. In all its motions, it is a perfect Empidonax. 



The plumage of the young differs from the adult in the paler fulvous 

 of the under parts. There are two bands of strong fulvous across the wings ; 

 the tertiaries are edged externally with same, and also, with the secondaries, 

 conspicuously tipped with ashy white.
