Nesting evidently begins in .May and oontiuues till August. There are few- 

 records of the taking of eggs, hut frequent reft-rences to feeding of young, most 

 of them in July. The earliest nesting reeord is that of a nest being built at 

 Kalispell, May 13, 1916, and the latest, of young being fed, at Big Fork, August 

 14, 1916 (Sloanaker, MS). A nest with two eggs was found at Flathead Laice 

 ■luly 2. 1902 (Silloway, 1908b, p. 296), and birds wei-e nrst building on the Teton 

 River, June 6, 1916 ( DuBois. MS). 



306. Nannus hiemalis pacificus (Bairdj 



Western Winter Wren 

 A sunuuer resident of the northwestei'u pai't i.if the state, and perhajis moi'e 

 rarely farther south. Probably permanent resident at low elevations, ('ommou 

 northward. Breeds in dense spruce forests or forests of arbor-vitae on the west 

 side of the divide, evidently nesting about stumps and logs on the ground. In 

 migrations occurs rarely east of the mountains. Records: Summer resident of 

 arbor vitae forests at Flathead Lake (Silloway, 1901a, \>. 71 ). Seen in fall, Fer- 

 gus County (Silloway, 1903a, p. 67). Gei-man (luleli. Silver Bow County, seen 

 May 23, and secured May 24, 1910, and seen on Cohl Creek, Powell Couut.v. 

 .Vugust 15, 1910 (Saunders, 1912a, |i. 31). A [lair with young seen on Beavei' 

 Creek, northern Lewis and Clark County, June 29, 1911 ; and one seen on IJii'ili 

 Creek, Teton County, May 31, 1912 (Saunders, 1914a. p. 142). Seen at Belton. 

 July 6 and September IS, 1915 (DuBois, MS). In 1915 this species was unusu- 

 ally common at Flathead Lake, several pairs with broods of six or seven young 

 being observed about old logs in spruce woods at Yellow Bay, in July. Common 

 in Glacier Park, wliere I have noted it in arbor-vitae forests wi.'st of the divide, 

 and in sjn^uee forests east of it. 



307. Telmatodytes palustris plesius (Cberholser) 



Western .M.vhsh Wren 



A summer resident of the western part of the state, and perhaps also in the 

 prairies eastward, in suitable localities. Local in distribution, and rare in mosr 

 places. A common breeder in the Bitterroot Valle.y (Bailey, ^IS). Breeds at 

 Swan Lake, where an unfinished nest was found July 26, 1902 (Silloway. 1903b, 

 p. 303), and probably near Kalispell, where I observed a liird August 17, 1914. 

 Seen at Chief Mountain Lake in August, 1874 (Coues, lS74b, ii. 555). Taken 

 in migration at Anaconda, April IS, 1911. two birds, and at Gold Creek, Sep- 

 tember 21, 1910 (Saunders, 1912a, p. 31 ). Breeds at Big Lake, Stillwater (-oun- 

 iy (Thomas, i\IS). though it .seems jirobable that these birds may belong to th" 

 more eastern form iluuiis. One of the Ana<'onda birds refei-red to above was 

 an intergrade with that sulispecies. 



Winters rarely. A bird that probably wintered in the vicinity of Helena 

 was seen there :\Iareh 12. 1911 (Saunders, 1912d. p. IdS). Observed in the Bit- 

 terroot Valley, December 26, 1912 (Bailey, 1913a, p. 94). and November 20. 1911 

 (Bailev, MS).
