 April 28, 1896 (Cooke, 1912, p. 99) , Bozeman, "Slay 4, 1909; Big Hole River,

 of three years October 7, latest October 16, 1906 (Cooke, 1912, p. 101). Boze- 

 man, September 13, 1908 ; Three Forks, October 17, 1909 ; Great Falls, Septem- 

 ber 18, 1886 (Williams, 1888a, p. 17) ; Livingstone, October 11, 1915 (Kitt-

Few nests are on record, though the White-crowned Sparrow nests com- 

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

 containing four eggs was found on Middle Creek, Gallatin County, June 21, 1909, 

 at an elevation of 7100 feet. Another nest was found by G. B. Thomas in June, 

 1909, near Bozeman, where the species breeds away from the mountains. 



231. Zonotrichia leucophrys gambeli (Nuttall) 



Gambel Sparrow 



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

 dently breeding, in the mountains of the northern part, particularly east of the 

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

 season, have mentioned the occurrence of this bird. It is found then chiefly in 

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

 summer on Birch Creek, Teton County (Saunders, 1914a, p. 138) and in 

 Glacier National Park. It is also reported to breed in the Belt ^lountains (Wil- 

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

 306). The latter record I believe to be an error for leucophrys. 



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 :\Iay 14, 1911 ; 

 Choteau, May 8 to 28, 1912; Great Falls, May 9, 1887 (AVilliams, 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, MS). Fall dates: 

 Gallatin County, September 26 to October 13, 1908; Powell County, September 

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

 and Kalispell, September 3 to 23 (Kittredge, MS). 



While this species undoubtedly breeds in the more northern mountains, 

 there is no record of the nest having been found. 



232. Zonotrichia albicollis (Gmelin) 



White-throated Sparrow 



A rare migrant in the eastern part of the state, occurring west to Gallatin 



and Cascade counties. Records: Great Falls, :May 12, 1890; Fallon, October 5, 



1908 (Cooke, 1912, pp. 102, 105) ; Fallon Creek, September 6, 1896 (Cameron. 



1908a, p. 40) ; Fort Keogh. September 22, 1900 (Hedges, coll. Univ. Montana^ ;
