The Connecticut Warbler is a not uncommon miii^rant in spring 

 and fall in Illinois and Wisconsin, and according to Kumlien and Hol- 

 lister a few breed in the latter state; although the majority go farther 

 nortli. They sa\-: " In Jefferson County a pair was found, June 16, 

 1874 (L. K.j, putting the finishing touches upon their nest. It was 

 placed on the ground in a dense thicket of hazel, briars, etc. Though 

 the nest was not touched they abandoned it, but bred in the same 

 thicket; the nest, however, could never be found. Has been found 

 in the dense tamarack swamps of Jefferson County in July, on several 

 occasions when it was, without question, nesting, and we have no 

 doubt that a considerable number nest within the state. It is the 

 very last w^arbler to pass northward in the spring. Many observers 

 fail to find this species. Mr. Ciark has not, as yet, taken it in Dunn 

 County, and it was not found in the state by King, Grundtvig, or 

 Willard." (Birds of Wisconsin, 1903, p. 117.)
