bird life, including many species of peculiar interest, especially when the 

 rough nature of the country and the density of the pine woods is considered. 

 Returning here September 19, many of the species found in August in 

 abundance had migrated south, and were either entirely wanting or repre- 

 sented by individuals from farther north, while the woods, the silence of 

 which was often unbroken for long intervals by the note of a single bird, 

 would now and then, as if by magic, be filled with hundreds of feathered 

 migrants, who in noisy companies were proceeding on their way south. 

 The day after establishing our camp here, Mr. Rutter, of the party, brought 

 in a fine specimen of this warbler, which he stated he had shot from among 

 a flock of Aububon's Warblers and Snowbirds, which he had started from 

 the ground while walking in the pine woods. With the rest, it had appar- 

 ently been feeding upon the ground, and had flown up to a low branch of a 

 pine, where it sat and began to give forth a very beautiful song, which he 

 described as consisting of detached, melodious, whistling notes. During the 

 next few days, I confined my collecting trips to the spruce woods, and 

 though I watched eagerly for this to me strange warbler, I did not see it 

 till the last day of my stay in the locality, when I heard a few strange 

 Vireo-hke notes coming from some thick pines, and, hurrying to the spot, 

 soon had the satisfaction of seeing one of these warblers on the low limbs 

 of a huge pine, where it was moving quickly over the large branches, its 

 manner and whole appearance reminding me instantly of the Pine Creeper 

 {Dciulroicapinus). A few moments later, a second specimen was shot from the 

 top of a tall pine, where it was actively creeping about. As all the warblers 

 present here at this time were migrants, we may reasonably infer that, with 

 the others, this species was en route from some locality to the north, and 

 perhaps it may be found to be a rare inhabitant of the high pine region 

 throughout Arizona and New Mexico.
