316 Warrex, Birds of the Elk Mountain Region, Colo. [j "ly 



in a dense thicket of Choke Cherry at Adams's ranch on Muddy Creek, 

 1901-2-3; the nest itself was not found except once in the fall after the 

 leaves had gone. The male was always singing near the nest. This species 

 does not occur in the Crested Butte region. 



Salpinctes obsoletus obsoletus. Rock Wren. — Summer resident; 

 breeds. Apparently rare about Crested Butte. A l)rood of young from 

 the nest were seen at Hillside Ranch, August 16, 1902. None seen there 

 in 1915, Ijut one noted June 28 just west of Crested Butte. 



Troglodytes aedon parkmani. Western House Wren. — Common 

 summer resident and breeder. Earliest spring date. May 5, 1900, at 

 Crested Butte. Latest fall date, September 7, 1902, but doubtless remains 

 later. Ranges to at least 10,500 feet. As ever>Tvhere breeds in all sorts 

 of locations. As noted under that species a pair had a nest in the same 

 tree with a Violet-green Swallow. A pair nested in between the slabs at a 

 corner of a shed at Hillside Ranch in 1903, which had left the nest July 20. 

 A family of young seen on Coon Creek, July 14, 1900. A Wren was noted 

 at nest hole in dead aspen on south slope of Crested Butte Mountain, carry- 

 ing food for young, June 8, 1915. During that month a pair had a nest 

 somewhere about the log house in which I stayed at Hillside Ranch, but 

 I could never discover its situation; in fact I think they changed its loca- 

 tion for a second brood. June 11, and for several days after they were 

 busy carrying food to the nest ; then they seemed to be making ready for a 

 new brood, and I thought they were 0(!cupying an old ClilT Swallow's nest 

 under the eaves on the end as I saw a Wren in it several times, but finally 

 concluded I was mistaken. There may have been some crevice in the roof, 

 under the log ridge poles, into which they could get. The latter part of the 

 month the male spent nuich of his time on a projecting pole at the end of 

 the roof, singing. 



Sitta carolinensis nelsoni. Rocky Mountain Nuthatch. — One 

 observed at Hillside Ranch, carrying food, June 29, 1903. The only record 

 I have of the species. 



Sitta pygmaea pygmaea. Pygmy Nuthatch.— One seen on Middle 

 Brush Creek, Septcml)cr 28, 1910. My only record. 



Penthestes atricapillus septentrionalis. Long-tailed Chick- 

 adee. — Resident, moderately common, but not seen as frequently as the 

 next species, and possibly does not go as high. I have notes for all seasons. 

 Seen at Marl)le; also on Muddy ('reek. 



Penthestes gambeli gambeli. Mountain Chickadee.— Resident; 

 common; seen at all seasons; goes to timberline. One day in September, 

 1901, I was surveying near Irwin, and while standing by the transit a little 

 band of Mountain Chickadees came very close to me and I could hear their 

 notes very distinctly. They seemed to say " chick-a-dee-a-dee-a-dee," 

 not " chick-a-dee-dee " as the Black-caps do. And the tone was also 

 different, but I cannot describe it. I did not hear them use the " phe-be " 

 call, nor would they answer when I whistled it. 



Regulus calendula calendula. Ruby-crowned Kinglet. — Summer
