i:4 PACIFIC COAST AVIFAUNA No. 14 



Other spriii.u' dales ai'e frdiii Choteau, May 12, 1912 (Saunders. 1914a, p. 138), 

 ami Slace.y, .May 19, 1917 (Kittredge, MS). The only fall date is from Great 

 Falls, September 9, 1891 (Cooke, 1909c, p. 260). 



While this bird occurs in summer throughout its range in the state, and 

 undoubtedly breeds, the finding of the nest has not been recorded. 



236. Spizella breweri ( 'assin 



Brewer Sparrow 



A common summer resident of eastern Montana, occurring westward to 

 Teton and Gallatin counties. There are not many records of occurrence, but in 

 most places where it has been found it is fairly common. It breeds in sage 

 brush, and is somew'hat more western in its range than iS'. pallida. 



Records: Common, breeds at Fort Keogh (Thorne, 1895, p. 217) ; numerous 

 on the Yellowstone and Musselshell (Allen, 1874, p. CS) ; common in Gallatin 

 County (Richmond and Knowlton, 1894, p. 306) ; rare in Teton County (Saun- 

 ders, 1914a, p. 138). 



The only date of migration published is from Fort Custer, May 15. 1885 

 (Cooke, 1909e, p. 260). The only nesting data are those of a nest and eggs found 

 at Fort Keogh, June 16 (Thorne, 1895, p. 217), and young out of the n^st found 

 at Sedan, Gallatin County, July 28, 1909 (Saunders, 1911a, p. 43). In addition 

 to the above records I have found this species common in the Shields River 

 Valley of noi'thern Park County. 



237. Spizella pusilla arenacea Cliadbourne 



Western Field Sparkuw 

 A rather rare summer resident of southeastern Montana. This is probably 

 one of the species that is characteristic of the Upper Sonoran zone. It is eithei- 

 rare, or else it is overlooked by most observers. It is reported from Billings, 

 August 12, 1900 (Jones and Dawson, 1900, p. 32), from the Long Pine Hills 

 along the South Dakota border (Visher, 1911, p. 14), and from Miles City, May 

 n, 1902 (Hedges, coll. Univ. Montana). These appear to be all the records. 



238. Junco aikeni Ridgway 



W I i ITK-WINGED JuNCO 



A permanent resident of southeastern .Montana in the pine hills. This sjie- 

 eies was evidently first found in the state by C. F. Hedges, there being a series 

 of eleven specimens in the Fniversity of Montana collection, taken by him in the 

 vicinity of Miles City between April 22 and 27, 1900, and a single specimen 

 from the same locality and date in the collection of L. B. Bishop. In November 

 and December, 1909, I found this species in the Long Pine Hills of Carter Couu- 

 t.y, close to the South Dakota border, securing one for identification December 

 5. The following summer the species was noted again in that place, young being 

 found in the Long Pine Hills, July 20, 1910 (Visher, 1911, p. 14). The species 

 was again found there, and also on thi> Custer National Forest in Rosebud County
