The Golden-winged Warbler is a rather common migrant and a 

 more or less common summer resident in parts of Illinois and Wis- 

 consin. Prof. Ridgway states he found it breeding on the southern 

 edge of Calhoun Prairie in Richland County, Illinois, in June, 1885, 

 and that Mr. H. K. Coale found it common and breeding on May n, 

 1884, in the woods on the Kankakee River in Stark County, Indiana 

 (Orn. of Illinois, 1889, p. 126). 



Messrs. Kumlien and Hollister state (Birds of Wisconsin, 1903, 

 p. in): "This superb warbler is a regular, though rather rare, mi- 

 grant and a summer resident from the southern part of the state 

 northward. Dr. Hoy took several nests at Racine and T. Kumlien 

 procured fledglings in Jefferson County. Grundtvig found it common, 

 in fact, 'extremely numerous' in Outagamie County in 1882-3. He 

 found it a common summer resident, but did not find a nest. Re- 

 corded by Willard as breeding in Brown County, and by Mr. J. N. 

 Clark from Dunn County. We have found it more common along 

 Lake Michigan than elsewhere and a rather common breeder at Two 

 Rivers in 1881. It is a regular summer resident in Jefferson County, 

 but as elsewhere is restricted to favorite localities." 



The nest is on or near the ground, composed of leaves, plant fiber,
