1921 BIRDS OF MONTANA 163 



iSn.J (ISetts, 1916, p. l(i:i). Thr. fact tliat time of these four records are in the 

 year 1!)1.5 suggests that this species was uuusually conuiion that year. Fifteen 

 years' previous work in the \ieinity of Flathead Lake liad not reveah^d its pres- 

 ence. Mr. Kittredge informed nie that he had met with the Chestuut-baeketl 

 C'hiekadee on the Lolo and Blackfeet National Forests, and that it shows a pre- 

 ference for forests of western wlute ])inr', a tree that is unconniion in ^Fontana, 

 except as scattered individuals. 



:jl!S. Reg'ulus satrapa olivaceus P.aird 



Western Golden-crowned Kinglet 



A common sununer resident of the mountains in the western half of the 

 state. Breeds in spruce forests in the Canadian zone, and west of the divide in 

 (he Transition zone. Occurs rarely away from tlie mountains in migration. 

 Winters rarely in valleys, and si ill more rai'el\' in the mountains. 'I'lie eastern- 

 most j)oint where it is reported to lireetl is m the mountains of 1^'ergus County 

 (Silloway, 1903a, p. 68). Jn southern Jlontana I have noted it in Park County, 

 west of the Yellowstone. It has been found once in migration in extreme eastern 

 ^Montana in the Long I'ine Hills of Custer County, November Ki, 1909 (Saun- 

 ders, 1916d, p. '20-i). This rei'ord m;iy refer to the subspecies siilrapn. as may 

 other recorils east of the divide in the state. All ^Montana specimens that I have 

 examined belong to ulirari iis. but, exce|it from Flathead Lake, they were not 

 iireeding birds. 



The migrations talce place in March and November. Three .years at ('olum- 

 bia Falls give an average of .'\Iaivh -;4, with the earliest March 121. lS9.i (Cooke, 

 1915c, p. ILI). Otiici' dates ai'e: Sour Dough Canyon, Gallatin County, March 

 2;"), 1909; Divide Creek. Silver iSow County, April 22. 1910. Fall dates are: 

 C'olnmbia Falls, Xovember 20, 1S92 (Cooke, 191."ic. p. 121 ) : Soui' Dough Canyon, 

 Gallatin County, Xovmber 24. 190S; Dry Cotlonwood Creek. D.cr Lodge Coun- 

 ty, November 5, 1910. Tliei-i' is a record of this species in migration away from 

 the mountains at Great Falls, rare in fall (Williams, 1888a, p. 1")). Winti-r 

 records are: Sour Dough ('anyou. Gallatin County, Febriiaiy 26, 1909 (Saun- 

 ders, 1:111a, p. -IS): I'.itterroot Valley, five seen December 10. i:in, three, De- 

 ceml)er 20, 1911, three, January 20. 1912. and the species common from -lanuar.v 

 20 till spring (Bailey, MS). 



There is no doubt that this species breeds, as it is 'ommon all summer in the 

 right ]ilai'es in the mountains, but the nest ajipiars not to have been found and 

 recorded. I have seen young out of the nest at Klathi'ail Lake, .luly 2:!, 19] I. 



319. Reg'ulus calendula calendula (Linnaeus)

 limits of its Ill-ceding range are found in the mountains of Teton Countv to tiu
