668. TOWNSEND'S WAKBLBE, Dendroiea townsendi 



(Towns.) 



Whenever we entered a particular clump of small firs and 

 bushes at Sin-yale-a-min Lake, a Townsend's warbler would 

 appear and manifest great anxiety by chirping in nearby shrub- 

 bery. The place was searched repeatedly for evidences of nest- 

 ing, but without avail. It is likely that the parent bird was 

 feeding a youngster in the thicket, for before the end of our 

 stay in the neighborhood the warbler had disappeared. We 

 noted one or two other instances of the occurrence of this 

 warbler at this camp. 



Townsend's warbler was noted only occasionally in our col- 

 lecting at the head of Flathead Lake. A specimen was taken 

 August 6, on the Helena Club grounds, opposite the Station 

 across the river, and an occasional note made thereafter re- 

 garding its presence in the woods in the neighborhood. It 

 was generally observed in a lower story of the woodland than 

 Audubon's warbler, frequenting about the same level as the 

 smaller flycatchers or the yellow warbler. 



680. MACGILLIVEAY'S WAEBLBE, Geothlypis macgilli- 

 vrayi (And.) 



Not uncommon near the Station, where it was found breed- 

 ing in June, though only one nest was noted. Specimens were 

 taken frequently in the woods during our August collecting. 

 This warbler is a bird of the bushes, like the yellow-throat, but 

 prefers bushes in low woodland to bushes near water. It was 

 frequently noted in our lists at Sin-yale-a-min Lake; and a 

 family Just from the nest was found at McDonald Lake. 



681a. WESTBEN YELLOW-THEOAT, Geothlypis trichas 

 occidentalis Brewst. 



This yellow-throat was not uncommon in the bushes along 

 Crow Creek, where its song was heard and specimens were 

 taken. It was also frequently noted in the shrubbery near our 

 camp at the foot of Flathead Lake, bordering the haw thickets. 



Common in the bushes and weeds of Daphnia Pond, where 

 it undoubtedly breeds, as it was regularly noted there both 

 during June and August. It was also freqiiently observed in 

 the bushes near the boat landing, in August.
