236 KENTUCKY WARBLER 



Adult <$, Fall. — Similar to adult c? in Spring but gray edgings to crown 

 feathers wider and more numerous, black at sides of throat tipped with yel- 

 lowish. 



Young 6", Fall. — Similar to adult <$ in Fall but crown more heavily tipped, 

 tips browner, black areas less pronounced. 



Adult 9, Spring. — Similar to adult 6* in Spring but generally duller, black 

 areas blackish or only dusky and more heavily tipped, tips brownish or olive. 



Adult 9 and Young ?, Fall. — I have no Fall females with both age and sex 

 accurately determined. The material at hand, however, indicates a difference 

 in females taken at that season similar to that observed in the male. 



Nestling. — Resembling nestling of G. trichas; the greater and median wing- 

 coverts are like the back and are tipped with rusty. 



General Distribution. — Eastern United States; north to New 

 York and Minnesota; west almost to the Plains. 



Summer Range. — The Kentucky Warbler is a forest lover and 

 makes its chief home in the heaviest timbered regions and dark, damp 

 woods of the central Mississippi Valley. Eastward it breeds more or 

 less locally from North Carolina to the lower Hudson Valley (Sing 

 Sing, Pleasantville) and to Pennsylvania (Chester, Delaware, and 

 Beaver Counties) ; occurs casually north to Connecticut (Suffield, 

 August 16, 1876, Lyme). 



There is a single record of its breeding in South Carolina 

 (Caesar's Head) and four records of its occurence during migration 

 in Florida. The Kentucky Warbler is common in the state from which 

 it takes its name, and in the watershed of the Ohio River and its 

 tributaries. It is uncommon north of this region, but is found as far as 

 Lake Erie — accidental in Quebec, southern Ontario (near London, 

 May, 1898), southern Michigan, southern Wisconsin (Racine, May 10, 

 1851, Lake Koshkonong) and southern Minnesota. 



The western limit of its range "is reached in southeastern Nebraska 

 (Omaha, Lincoln, Peru) and thence through eastern Kansas (Leaven- 

 worth, Atchison, Manhattan) to eastern Texas (Navarro County, 

 San Antonio ; in migration at Corpus Christi) . 



Though not uncommon in favorable localities along the streams 

 of these states, it is not nearly so abundant as in the Ohio Valley. 



It breeds principally below an elevation of 1,000 feet, but at Ashe- 

 ville, N. C, it breeds at 2,000 feet altitude, and has been noted up to 

 3,500 feet. 



Winter Range. — Southern Mexico to Colombia, South America. 

 Accidental in the West Indies. 



Fall Migration. — The southward movement begins the last of 

 July, and on October 7 the species has been taken at the extreme 

 southern limit of its known range in Colombia, South America. Some
