Breeding range. — The pine warbler breeds throughout the eastern 

 part of the United States from Florida and the Gulf States northward 

 to New Brunswick, Ontario, and Manitoba. One of the northern- 

 most points from which it is recorded is Carlton, Saskatchewan, where 

 a party of the Biological Survey found it common during July, 1895. 

 The northern boundary of the breeding range of the species is in the 

 Canadian life zone, but comparatively few individuals nest north of 

 the Alleghenian zone. In the region of the plains, where pine for- 

 ests are lacking, it is a rather rare migrant. It was secured once 

 at Revelstoke, British Columbia. Nearer the Mississippi River and 

 thence to the Atlantic Ocean its presence during the breeding season is 

 largely governed by the extent of pine timber. Hence in summer it 

 is more common in the Southern States and the pitch and white pine 

 districts of southern New England than in the middle hard-wood dis- 

 tricts, throughout which, from about latitude 37° northward, it is 

 known to most observers as a more or less common migrant and to a 

 few as a rather rare summer resident. 



Winter range. — The pine warbler is a rare winter resident in eastern 

 Texas south to Corpus Christi. From North Carolina and southern 

 Illinois southward it is common in winter in the pines. Occasionally 

 at this season it winters north to Massachusetts. It has not yet been 

 reported from Cuba or the islands at the south of Florida, nor have
