It is doubtful if this species has ever actually been taken in 

 Illinois, although it undoubtedly occurs in the southern portion of the 

 state. Mr. Ridgway in his Notes on Birds observed at Mt. Carmel, 

 southern Illinois, in the spring of 1878 (Bull. Nutt. Orn. Club, 1878, 

 p. 163) states: "In the Cyprus swamp a bird was several times no- 

 ticed by Mr. Brewster and myself, which we both agreed must be 

 this species. It was well seen on several occasions and its ' song 

 heard, while one specimen was shot, but unfortunately could not be 

 fouhd." In the synonomy of his Birds of North and Middle America 

 (1902, p. 438) he refers to this record as from "Knox Co., Indiana," 

 from which it would appear that the birds were observed on the 

 Indiana side of the Wabash River. 



Mr. Otto Widmann gives Swainson's Warbler as a summer resi- 

 dent in southeast Missouri (Birds of Missouri, 1907, p. 214). 



Mr. Alfred O. Gross records having seen a Swainson's Warbler 

 near Du Quoin, Perry County, Illinois, on June 17, 1907. (The 

 Auk, Vol. XXV, 1908, p. 225.)
