At Fort Garland, Col., a warbler was seen June 25 in a grove of pine 

 trees on the sides of a narrow canon, which I am quite confident was of 

 this species. It had a short, feeble, but rather pleasing-, song, which it con- 

 stantly emitted at short intervals as it flew from tree to tree. Owing to its 

 sliyness, I did not succeed in capturing it. 



The dry foot hills in the vicinity of Santa Fe, N. M., covered with a 

 growth of pinons and cedars, were frequented by these birds in June. I saw 

 no females ; but the males were in very much worn plumage, and had all the 

 appearance of breeding-. The nests, however, I did not succeed in finding. 

 In the fall migrations, their numbers increase, and they are then found quite 

 abundantly in Arizona, frequenting usually the pines, more rarely the oaks 

 and other deciduous trees. Thg following remarks Mr. Aiken furnishes from 

 notes in Colorado : 



" Rather a rare migrant in Colorado ; a few probably remaining to breed. 

 I have never seen it anywhere but on the mesas and foot hills that are cov- 

 ered with the low scraggy pifion pine. In the spring time, it first makes its 

 appearance about the first of May ; two or thr-ee males usually being 

 together then, and the females coming several days later. The male, as he 

 searches for insects on leaf and limb, repeats at intervals a singular, but 

 withal a very pretty, song, with something of the metallic ring in it that is 

 heard in the song of the White-throated Wren. Shy and retiring- in its 

 habits, and frequenting piflon groves so dense that one can scarcely see a 

 dozen }'ards ahead, this ornate little sylph is very easily overlooked, and it 

 often requires considerable perseverance to secure a specimen, even after 

 it has been discovered. I have followed one through the thicket for half an 

 hour, while, like an iffnis fatuiis, it led me on, fluttering occasionally into 

 sight for an instant, and a moment later uttering its song- perhaps twenty 

 rods away."
