bier is heard much later in the summer than that of the Townsend 

 warbler. 



Distinguishing features: Upper parts bluish gray, back streaky; 

 Dead with a partially concealed crown of yellow; rump yellow; throat 

 yellow; large patch of white on wings; other lower parts whitish, streaked 

 with black; length 5-6 inches. 



661. BLACK-POLL WARBLER. Dendroica striata. 



A regular migrant, the first for 1903 having been seen May 13. At 

 the close of the storm which prevailed during the week of May 16-23, 

 1903, a specimen of black-poll warbler was sent me from Deerfield by Mr. 

 Theo. Hogeland. It was a male, which had evidently fallen a victim of the 

 storm. The skin is now in the collection of the Fergus County high school. 

 This warbler is reported as common at Ft. Keogh, where Capt. Thorne 

 met it as a migrant in the latter part of May. 



Distinguishing features: Crown, black; sides of head, throat, under 

 parts, and edges of wing-coverts, white; upper parts striped with black, 

 gray, and darker; sides streaked with black; length about 5 inches. 

 675a. GRINNELL'S WATER-THRUSH. Seiurus noveboracensis notabilis. 



Dr. J. A. Allen notes that a water-thrush, probably S. noveboracensis 

 Nutt., was seen at the Big Bend of the Musselshell. Capt Platte M. Thorne 

 leports a specimen taken at Ft. Keogh September 12, 1889. This water- 

 thrush is a very common resident of the Flathead region in summer, where 

 its loud, clearly enunciated song is a characteristic of the swamp-woods. 



Distinguishing features: Upper parts grayish brown; dull yellow 

 stripe above eye; lower parts whitish, with a yellow tinge, streaky; length 

 about 6 inches. 



680. MACGILLIVRAY'S WARBLER. Geothlypis tolmiei. 



This handsome ground warbler is a regular summer resident of the 

 foothills and mountains in the western districts of the county, and is oc- 

 casionally noted in the more eastern portions. Dr. J. A. Allen says that 

 it was seen a few times along the Musselshell. It is likely that this warbler 

 occurs in the Judith and Moccasin Mountains, though I have no informa- 

 tion regarding such occurrence. 



Distinguishing features: Head, neck, and chest ashen-gray; sides of 

 head varied with black; other upper parts olive-green; other lower parts 

 bright yellow; length 5-6 inches. 

 681a. WESTERN YELLOW-THROAT. Geothlypis trichas occidentalis. 



A common inhabitant of this region in summer, usually appearing 

 in the second week of May, and announcing its presence by its familiar 

 "wich-i-ty, wich-i-ty, wich-i-ty" song, one easily identified after once being 

 closely noticed. The male yellow-throat is a handsome little creature, eas- 

 ily recognized by the black mask marking the face and upper part of the 

 head, the other parts being bright yellow. The female is no less hand- 

 some, having a plumage of bright yellow, the throat being noticeably 

 bright, but she lacks the black marking of the male and hence is more 

 easily confounded with other yellow birds. This warbler resorts to the 

 vveeds and bushes of moist places, irrigating ditches, and borders of ponds
