A common migrant in Illinois and Wisconsin in spring and fall. 

 Nelson says, "A few remain to breed." (Birds N. E. 111., 1876, p. 100.) 



Regarding its occurence in Wisconsin, Messrs. Kumlien and Hoi- 

 lister say: "As is the case with many of the warblers, this one occurs 

 in varying numbers, being sometimes only fairly common, and again 

 greatly abundant, either in spring or fall. Dr. Hoy wrote that a 

 few nest with us, and Mr. Clark suspects that they breed in Dunn 

 County, as he has found' them during the summer months. Young 

 just able to fly were taken in Jefferson County in July, 1868, and 

 adults are frequently seen in summer as far south as Rock, Dane, and 

 Jefferson Counties. W T e have known several pairs to remain in the 

 vicinity of Milton all 'summer, but have never succeeded in finding a 

 nest." (Birds of Wis., 1903, p. 115.) 



The nest is is a tree, usually at a considerable height. The eggs 

 are 4 in number, white, spotted with various shades of brown, and 

 measure about .68 x .49 inches.
