48 Saunders, Birds of Gallatin Co., Mont. [jan" 



served a bird of this species in a clump of tall grass along the Missouri 

 River at Lombard on April 22, 1909. 



*185. Certhia f amiliaris montana. Rocky Mountain Creeper. — 

 A rare summer resident in spruce forests in the mountains. Seen more 

 often during migrations but by no means common then. The migrating 

 birds were noted from Sept. 11 to Nov. 10, 1908, and from March 25 to 

 April 16, 1909. I observed it once in winter near Ross's Peak, FebT 17, 

 1909. 



186. Sitta carolinensis nelsoni. Rocky Mountain Nuthatch. — 

 Rare but probably permanent resident. Richmond and Knowlton found 

 it breeding. I noted it but twice, Sept. 28, 1908, and Feb. 27, 1909. 



187. Sitta canadensis. Red-breasted Nuthatch. — Migrant. 

 Quite common in fall. Noted from Sept. 7 to Oct. 24, 1908, and from 

 April 16 to May 25, 1909. 



*188. Penthestes atricapillus. Chickadee. — A Chickadee, taken at 

 Bozeman, Nov. 26, 1908, was identified as P. a. atricapillus by Dr. Bishop. 

 This bird had the breast stained dark gray, a common occurrence among 

 winter Chickadees in this region and said to be caused by living in burned 

 timber. Since there are no large bodies of burned timber in this region 

 it is apparent that they migrate from elsewhere. Thinking that all the 

 dark-breasted birds might belong to this form I secured another at Three 

 Forks in February, 1910. This bird, however, proved to be the usual 

 form, P. a. septentrionalis. 



*189. Penthestes atricapillus septentrionalis. Long-tailed 

 Chickadee. — Abundant permanent resident in willow thickets in the 

 valleys and mountain canons to about 6,500 feet. 



190. Penthestes gambeli. Mountain Chickadee. — Permanent 

 resident in the mountains. In October it may be seen occasionally in the 

 valleys with the above species. 



*191. Regulus satrapa olivaceus. Western Golden-crowned 

 Kinglet. — Abundant migrant and rather uncommon summer resident in 

 spruce forests in the mountains. Occasional as a winter resident in com- 

 pany with Mountain Chickadees. 



192. Regulus calendula. Ruby-crowned Kinglet. — Common 

 summer resident in the mountains. In migrations this species occurs in 

 willows in the valleys but in the breeding season is found only in forests of 

 Douglas fir. The song of this species in this region is quite different from 

 that of eastern Kinglets. The first two parts are much alike but in the last 

 part, in place of the triplets of the eastern bird, there are a series of double 

 notes on the same pitch, the first note of each double accented. When 

 only the last part of the song is rendered, as is frequently the case, it closely 

 resembles a common call of the Tufted Titmouse. 



193. Myadestes townsendi. Townsend's Solitaire. — Summer resi- 

 dent in the mountains but more common during migrations. It does not 

 breed below 7,000 feet to my knowledge, but during migrations is common 

 in the foothills and lower forests. It appears to sing better and more
