Few nests an- on rceord. though the Whiti'-erowned Sparrow nests eom- 

 monly enough in the mountains of the southwestern iiart of the state. A nest 

 containing four eggs was found on Middle Creek, Gallatin County, Juni' 24. 1909. 

 at an elevation of 7100 U'vt. Another nest was found by G. B, Thomits in Juni'.

231. Zonotrichia leucophrys gambeli (Xiittall) 



Gambel Sparrow 



A common migrant throughout the state, being found in summer, and evi- 

 dentl.y breeding, in the mountains of the northern part, particularly east of the 

 continental divide. All observers who have done work during the migration 

 season, liave mentioned the occurrence of this bird, ft is found then chiefly in 

 the mountain valleys, and on the jjrairies along streams. It has been found in 

 summer on Birch Creek, Teton ('ounty (Saunders. 1914a, p. DiS) and in 

 Glacier National Park. It is also reported to bi'eed in the Belt Mountains (Wil- 

 liams. 1888a, J). 17) and in Gallatin County (Richmond ami Knowlton, 1894, p. 

 o06). The latter record I believe to be an en-oi- for Iciicdpliriis;^ 



Migration dates are as follows: Gallatin County, May 8 to 19. 1909; Silver 

 Bow County. May 5 to 12, 1910; Deer Lodge County, April 29 to May 14. 1911 ; 

 Choteau, May 8 to 28, 1912; Great Falls, May 9, 1887 (Williams, 1888a, p. 17) ; 

 Bitterroot Valley, April 29 to May 20, 1911, May 3 to 22, 1912. April 28 to May 

 22, 1913 (Bailey, MS) ; Dutton, May 4 to 21, 1916, May 9 to 18, 1917 (DuBois. 

 MS) ; Missoula and Kalispell, May 2 to June 7 (Kittredge, ]\rS). Fall dates: 

 Gallatin Count.y, September 26 to October 13. 1908: Powell County. Septemtipr 

 21 to Oetober 9. 1910; Teton County, September 23 to October 1. 1911 : Missoula 

 and Kalispell, Sejitember 3 to 23 (Kittredge. :MS). 



While this species undoubtedly bi'-eds in the more northern mountains, 

 there is no record of the nest having been found.
