 The Yellow-bellied Woodpecker is a common spring and fall mi- 

 grant in Illinois and Wisconsin, and an occasional summer resident 

 in northern Illinois and Indiana. It is a common summer resident 

 in Wisconsin, where according to Kumlien and Hollister, it breeds in 

 considerable numbers as far south as Lake Koshkonong (Birds of 

 Wisconsin, 1903, p. 76). Mr. John F. Ferry procured a nest of young 

 birds at Woodruff, Wisconsin, June 25, 1908. It occurs more or less 

 commonly as a winter resident in southern Illinois. 



The nest is a hole in some large tree or stump, usually 30 or more 

 feet from the ground. The eggs are white, six or seven in number, 

 and measure about .85 x .66 inches.
