44 Saunders, Birds of Gallatin Co., Mont. [j^, 



146. Amphispiza nevadensis. Sage Sparrow. — An abundant 

 summer resident in the East Flathead Valley. The only other place that 

 I have found it is in the Gallatin Basin where I heard several birds singing 

 in July. 



*147. Melospiza melodia montana. Mountain Song Sparrow. — 

 Abundant summer resident in willow thickets in the valleys and along 

 mountain streams to at least 7,500 feet. It is also quite a common winter 

 resident as high as 6,500 feet. The spring song period begins very early 

 so that it is impossible to distinguish migrants from winter residents 

 with certainty. The spring migrants, however, evidently arrive by April 1, 

 if not sooner. 



148. Melospiza lincolni. Lincoln's Sparrow. — An abundant 

 summer resident in willow thickets in the mountains, above 6,500 feet. 

 It arrives early in June, occurring in the valleys, in small numbers, for a 

 few days. The fall migration apparently begins early, for I have found 

 it in the valleys again by July 30. It remains until early September. 



*149. Passerella iliaca schistacea. Slate-colored Fox Sparrow. — 

 Abundant summer resident in willow thickets in the valleys, arriving early 

 in April. It prefers the thickest and most impenetrable of the willow 

 thickets. For this reason it is more often heard than seen, and I have no 

 records of its occurrence after July 10, when the song period ceases. 



150. Pipilo maculatus arcticus. Arctic Towhee. — Abundant 

 summer resident in thickets of willow, wild-rose and thorn in the valleys 

 and foothills. It arrives in the middle of May and leaves by the middle 

 of September. 



151. Oreospiza chlorura. Green-tailed Towhee. — Summer resi- 

 dent in the foothills in wild-rose and thorn thickets. It arrives in the 

 latter part of May. It is much less common than the above species, 

 though usually found in company with it. 



152. Zamelodia ludoviciana. Rose-breasted Grosbeak. — Mr. 

 Thomas observed a male of this species on Church St., Bozeman, on two 

 different occasions in June and July, 1909. On the first occasion it was in 

 company with a male of the next species. 



153. Zamelodia melanocephala. Black-headed Grosbeak. — 

 Summer resident in the valleys, inhabiting the willow thickets. I have 

 not seen this species in the East Flathead Valley nor in the other valleys 

 above 5,000 feet. It arrives late in May. 



154. Passerina amoena. Lazuli Bunting. — Common summer 

 resident, inhabiting wild-rose thickets in the valleys and foothills. Arrives 

 in the latter part of May and leaves in August. 



155. Calamospiza melanocorys. Lark Bunting. — Summer resi- 

 dent. I noted only a few individuals of this species during the spring 

 migration from May 24 to June 13, 1909. Mr. Thomas found it breeding 

 commonly at Three Forks and Prof. Cooley told me that in 1907 it ap- 

 peared in large numbers and bred throughout the Gallatin Valley, but 

 that he had not seen -it since then.
