MNIOTILTIDffl — THE AMERICAN WARBLERS. 131 



Warbler, this species breeds abundantly in the extreme north, being 

 particularly numerous in the McKenzie River district ; but it is ap- 

 parently wanting to the Alaskan fauna. The southern portion of 

 its breeding range includes the northern shores of the Great Lakes 

 and a considerable portion of New England, including parts of 

 Massachusetts. Its nest, like that of other species of its genus, is 

 built on the ground. The song is said to resemble that of the 

 Nashville Warbler, except that it is shriller.
