'' Migratory. Arrives from the South in May, and from the 

 North during the last week in August and in September. Fre- 

 quents the larger trees — deciduous rather than evergreens — and 

 sings more than many of the migrating species. A few remain 

 during the summer, and are then generally to be found in the 

 dark, silent swamps."

 inches ; tail, 2J inches. 



" Rare. Seen occasionally in May, but more frequently in 

 September, when the warblers are generally returning to the 

 South. Author knows of no instance of its breeding in the 

 State."— [0. C. A.]
