454 HISTORY OF THE 



nesota and Montana northward, in suitable localities throughout 

 their range, which I feel confident will be found to extend much 

 farther north than Manitoba, its present northern limit as given. 

 Capt. Chas. Bendire describes in "The Auk," Yol. 6, p. 150, a 

 nest containing four eggs, found June 24, 1885, in a willow 

 thicket near Fort Ouster, Montana, which he thinks will prove 

 to be the nest and eggs of this bird; and Bidgway says: "Eggs 

 (identification somewhat doubtful), .87x.68; buffy whitish, 

 thickly speckled with burnt umber, slightly mixed with purplish 

 gray."
