28 \V ARBITER SONOS. 



September, but I can find no evidence of another song period 

 then. 



The range is the same as the other eastern Warblers, reach- 

 ing the Plains in the west and Hudson Bay Territory in the 

 north. 



To"wnsend's Warbler. Dendroica toiunsendi. 668. 



Of this western species Mr. Merrill says: "The song is 

 like de, dc, de-dc, de, all especially the first three notes, like 

 Black-throated Green. It is different later in the season." 



Western North America, east to central Colorado, north to

 north to Michigan and southern New England. 



Macgillivray's Warbler. Geothlypis tolmiei. 680.

 resemblance to the song of Dickcissel. 



It is a bird of the western United States, from the eastern 

 foot hills of the Rockies to the Pacific coa.st, and north into 

 British Columbia. 



Hooded Warbler. ]\lisonia mitrata. 685. 



Mrs. Wright represents this Warbler's song thus : che-
