120 PACIP'IC COAST AVIFAUNA No. 14 



The only information coneerning nesting; is from Custer and Dawson eoim- 

 tips. Tlu're the eggs are laid by the middle of June, the young are out )\v July 

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



229. ZonotricMa querula ( .Xuttall) 



Harris Sparrow 

 A i-are fall migrant in the eastern part of the state, oeeurring westward 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 

 Custer, 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 

 Ivnowlton, Custer County, one bird seen ^lay 24-25, 1907 (Cameron, 190Sa, 

 p. 40). 



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



AViIITE-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 chiefh' 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. Pew specimens have been taken in the bi-eeding season, but Icucup/irys and 

 ijaiiiliili are not difficult to distinguish in the field, when seen closely and in a 

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

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

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

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



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

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

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

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

 both leueophrys and gambeli in Glacier National Park, where frequent observa- 

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

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

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

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

 It has been observed at Belton, July 14. 1915 (DuBois, MS). 



The migrations take place in Ajiril and May in the spring, and during 

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

 beli, are found together at those seasons, it is often difficult to sejjarate them 

 and be sure of dates for each. The general data, however, indicate that gambeli 

 arrives a little earlier in sirring, and leaves a litth' later in fall, than h ucuphrys.
