General Distribution. — Eastern Texas, Mississippi Valley, and 

 north Atlantic States. 



Summer Range. — Gulf States east to Alabama, Mississippi 

 Valley as far west, casually, as eastern Nebraska (Havelock, April 20, 

 1901), South Dakota (Black Hills), Wyoming (Cheyenne, May 30, 

 1888), Colorado (Fountain, May 11, 1870) ; north to northern Wis- 

 consin, northeastern Minnesota (St. Louis Co.,), Michigan (Spectacle 

 Reef); east through central Ontario (Ottawa, Algonquin Park), 

 Prince Edward Island, New Brunswick (rare or local). Nova Scotia, 

 northern Maine; south to southern New England and casually 

 further and along the Alleghenies to North Carolina. 



The apparent derivation of the New England birds from the 

 Mississippi Valley is paralleled by the distribution of Geothlypis trichas 

 trichas. 



Winter Range. — Mexico and Central America. 



Spring Migration. — Records from the South Atlantic States 

 doubtless relate to both the southern Parula (Compsothlypis americana 

 americana) and the northern Parula (C. a. usnece) ; those from the 

 northern States and Mississippi Valley to the northern Parula only.
