The Blue-winged Warbler is a rare migrant. There are but 

 few known instances of its occurrence within our limits. These 

 are all recent and are as follows: Mr. B. T. Gault observed it 

 in DuPage County, Illinois, on August i8, 1894; on September 

 I, 1894, and on June 6, 1895. The last observation was that of a 

 male in song and the bird seemed to have settled for the season 

 in the Addison woods. However, Mr. Gault again visited the 

 Addison woods on June 22, but it was evidently too late for he 

 did not find the bird. On May 30, 1900, while at Palos Park, 

 on the Wabash railway, he heard the notes of this Warbler in a 

 bushy field, in a somewhat elevated situation, but did not see the 

 bird. Mr. Eliot Blackwelder observed it in Morgan Park on 

 May 24, 1895. This species was observed in June, 1906, by Mr. 

 John F. Ferry, but the nest could not be located. As this species 

 is known to breed in the southern part of Illinois, and as a juve- 

 nile bird has been taken by Mr. Gault in DuPage County, it does 

 not seem impossible that a very few individuals may remain and 

 breed within our limits. 



The range of this Warbler covers the United States, east of 

 the Great Plains and from Massachusetts, southern Michigan 

 and southern Minnesota southward. It breeds quite throughout 

 its United States range and winters from Mexico southward to 

 Guatemala and Nicaragua.

This Warbler is not an uncommon migrant which may be 

 looked for from the first to the last of May, and from the last 

 of August to the last of September. Regarding the occurrence
