stiitc, and so far reported only in spring. Recorded as i'ollo\vs : Fort Keogh. 

 eonnnon in May (Thorne, 1895, p. "218). Regular migrant in Fergus County, 

 .\lay i;^ and 28, 1903 (Silloway, 1903a, p. 64). Great Falls, average of three 

 years May 19, earliest May 18, 1892 (Chapman, 1907. p. 96). Ciioteau, eoninion

286. Dendroica virens (Gmelin) 

 Black-throated Green Warbler 



One seen on the Teton River below Collms, June 4, 1916 (DuBois, MS). 

 While this is a sight record only, the species is easily identified, and ^Ir. DuBois 

 was previously acquainted with it. I expect that sooner or later most of the 

 eastern warblers will be found to occur occasionally in the prairie region of the 

 state in migrations. 



287. Dendroica townsendi (J. K. Townsend) 



TowNSEND Warbler 



A common summer resident of northwestern Montana, west of the .conti- 

 nental divide. This species has been found in the following localities : Columbia 

 Falls (Cooke, 1904a, p. 91) ; Flathead Lake (Sillovvay, 1901a, p. 69) ; Belton 

 (UuBois, jMS) ; and Glacier National Park, where I observed it in the summers 

 of 1914 and 1915. It has also been found during migration in extreme eastern 

 .Montana, in Custer County and at Great Falls, as detailed below. 



Migration dates are as follows: Average arrival at Columbia Falls, May 

 7, earliest May 4, 1897; Great Palls, ]\Iay 28, 1890 (Cooke, 1904a, p. 90) ; Custer 

 County, Jlay 18, 1894, and Jlay 11, 1896 (Cameron, 1908a. p. 50). Fall de- 

 parture: Columbia Falls, August 17, 1895 (Cooke, 1904a, p. 91) ; Belton, August 

 27, 1915 (DuBois, MS). 



The nest has been found twice at Flathead Lake. The first, found July 

 15, 1903, contained five well grown young, which were afflicted with parasites 

 (Silloway, 1903b, p. 299). The second nest was found June 2, 1906, and con- 

 tained five eggs advanced in incubation (Silloway, 1906, p. 110 I.
