SWAMP SPARROW. 139 



You can not go far afield without meeting this singer. 

 He is not only our commonest Sparrow, but one of our 

 commonest birds. Generally you will find him on or 

 near the ground at the border of some undergrowth, 

 and if there be water near by, preferably a meadow 

 brook, his presence is assured. When flushed he will

 monotonous tweet-tiveet-tweet, repeated many times and 

 occasionally running into a trill. 



The Swamp Sparrow nests from northern Illinois 

 and Pennsylvania northward to Labrador. Its nest and 

 eggs resemble those of the Song Sparrow. It is migra- 

 tory in the northern part of the range, and is rare in win-

 seen, birds of the lowlands, though the latter also inhab-
