 Washington and British Columbia; north to Nova Scotia,

 northward throughout all wooded regions. In winter through

In Missouri the most evenly distributed woodland summer 

 resident from April till October. It is equally at home in the 

 overflowed region of the southeast as on the driest hilltops 

 of the Ozarks and in the small wood-patch left on northern and 

 western farm lands. It begins to sing soon after its arrival, 

 which is in the southeast as early as April 10; at St. Louis 

 and central Missouri generally between April 21 and 26, some- 

 times even earlier as April 16, 1896, April 17, 1885; and along 

 the northern border about the first of May. Its song is heard 

 all spring and summer, even during the hottest hours, when 

 most other birds are silent. After a silence of five or six weeks 

 the song is taken up again before its departure and is heard as 

 late as September 21, 1895, and September 24, 1887. The bulk 

 of transients passes through early in May, and again about the 

 middle of September. The species is scarce after September 

 25, but October records are not rare, October 1, 1895, being the 

 last for Keokuk and October 10, 1885, for St. Louis.

With the exception of one, May 8, 1898, from Independence 

 by Mr. Chas. Tindall, there are no records of the occurrence of 

 this species in western Missouri. In eastern Missouri it is a
