This Warbler is a common migrant, arriving from early in 

 April to the middle of May, and returning in the fall from about 

 the middle of August to the first of October. In 1876, Mr. E. W. 

 Nelson reported this creeping Warbler to be a not uncommon 

 summer resident, but I can find no other records of its occur- 

 rence within our limits during the summer months. 



The range of this species extends over eastern North Amer- 

 ica, east of the eastern base of the Rocky Mountains and from 

 the Fur Countries southward, in winter, through the West Indies 

 and Central America to Colombia. It breeds from the southern 

 states northward.

The Prothonotary Warbler is a rare summer visitant. It 

 breeds abundantly along the Kankakee River which seems to be 

 the northern limit of its breeding range in Illinois. Occasionally 

 these Warblers are seen within our limits. Mr. E. W. Nelson 

 says: "Two specimens were taken during the summer of 1875, 

 and I have heard of several other instances of its occurrence. 

 All specimens taken in this vicinity have remarkably dull colored 

 plumage." Mr. H. K. Coale reports it as having been seen or 

 taken in Cook County in May, 1883. Miss Amalie Hamnig, who 

 is familiar with this species, writes me that she observed a 

 brightly colored male at Riverside, Illinois, on June 2, 1897. Mr. 

 B. T. Gault noticed one at Glen Ellyn, Illinois, on May 13, 1893. 

 Mr. O. M. Schantz informs me that he saw a pair of these War- 

 blers at Morton Park on May 15, 1904. During the year 1904 

 the Prothonotary Warbler was also seen in Lincoln Park, Chi- 

 cago. It is my belief that this beautiful bird if encouraged and 

 protected may eventually become more common within our limits 

 and may possibly nest here 



While this species is more abundant in the Mississippi Val- 

 ley, where it breeds abundantly, its range extends from Cuba and 

 South America, in winter, northward to Pennsylvania, Michigan, 

 Illinois, Iowa and Nebraska. Casually it is found further north 

 in New England, Ontario and Minnesota.
