120 PACIFIC COAST AVIFAUNA No. 14 



The only information concerning nesting is from Custer and Dawson coun- 

 ties. There the eggs are laid by the middle of June, the young are out by July 

 15, and there is probably a second brood (Cameron. 1908a, p. 39). 



229. Zonotrichia querula (Nuttall) 



Harris Sparrow 

 A rare fall migrant in the eastern part of the state, occurring westwai-d to 

 Cascade and Gallatin counties. Very rare in spring. Records are as follows: 

 Fort Keogh, September 22 to October 13, 1889 (Thorne, 1895, p. 217) ; Fort 

 (hister, October 21, 1885 (Cooke, 1913b, p. 303) ; Miles City, one September 22, 

 1900 (Hedges, coll. of L. B. Bishop) ; Gallatin Valley, October 11 to 29, 1913, 

 October 13, 1915, and October 20 to 30, 1916 (Lundwall, MS) ; Great Falls, 

 October 10, 1915 (Kittredge, MS). There is a single spring record, from 

 Knowlton, Custer County, one bird seen ]\Iay 24-25, 1907 (Cameron, 190Sa, 

 ]). 40). 



230. Zonotrichia leucophrys leucophrys (J. R. Forster) 



White-crowned Sparrow 



A common summer resident of the mountains east of the continental divide, 

 particularly southward. Common in migrations throughout the state, and may 

 breed rarely west of the continental divide. Found chiefly in the Canadian 

 zone, but in some localities breeds down into the upper Transition in the valleys, 

 where these are not far distant from the mountains. The status and breeding 

 range of this subspecies, as compared with the next, are not thoroughly worked 

 out. Few specimens have been taken in the breeding season, but l( ucop/n-ijs and 

 (/amheli are not difficult to distinguish in the field, when seen closely and in a 

 clear light. At present the data seem to show that leucoplirys breeds throughout 

 the western half of the state, east of the divide, and that gamhcli breeds in the 

 northern half of the mountainous section of the state, over the same areas as 

 leucophrtja. There appear to be no intergrades between the two forms. 



1 have observed a sitting female of leucophrys in Gallatin County from a 

 distance of three or four feet. In Teton County 1 fed birds in a corral where 

 they were exceedingly tame and allowed an approach to within five or six feet, 

 and where they remained all summer. In the summers of 1914 and 1915 I found 

 both leucophrys and gamheli in Glacier National Park, w'here frequent observa- 

 tions showed that the two forms were about equally common. I have never seen 

 fjauibcli in the mountains of the southern part of the state in the breeding sea- 

 son. Leucophrys has been taken on the Madison River. August 12, 1872 (Merri- 

 am, 1873, p. 687), and at Flathead Lake, June 9, 1906 (Silloway. 1907, p. 53). 

 It has been obsci'wd at Helton. July 14. 1915 ( DuBois, :\rS). 



Tile migrations take place in Api-il and ^May in the spring, and during 

 September and October in the fall. Since the two forms, leucophrys and (jaui- 

 beli, are found together at those seasons, it is often difficult to s('i)ai';it(' them 

 and be sure of dates for each. The general data, however, indicate that ya»ibeli 

 arrives a little earlier in spi'ing, and leaves a little later in fall, than leucoplirys.
