176 HOUSE WREN. 



only long enough to give voice to his feelings in fidgetty, 

 scolding notes, or an effervescing, musical trill, with the 

 force of which his small body trembles. It is a wonder- 

 ful outburst of song, and the diminutive singer's enthu- 

 siasm and endurance are even more remarkable. The

 This is the Winter Wren, a bird that nests from north- 

 ern ^N'ew England northward and southward along the 

 crests of the Alleghanies to ^N'orth Carolina. It remains 

 with us in small numbers throughout the winter, return- 

 ing to its summer home in April. Mr. Burroughs writes 

 of the Winter Wren's song as a " wild, sweet, rhythmical
