 The Wood Thrush is a summer resident in Illinois and the greater 

 part of Wisconsin from May until the latter part of September. It 

 is a delightful songster, probably the best of this group of celebrated 

 avian vocalists. It is useless to attempt to describe the song; no 

 adequate idea of it can be conveyed in print, as combined with its 

 peculiar sweetness the peace of the woodland solitude adds to its 

 charm and it must be heard to be appreciated. 



Breeds in May and June. The nest is in woods, built .on the 

 branch of a low tree, rarely more than 10 feet from the ground and 

 is made of leaves, small twigs, and mud. The eggs are 3 to 5, plain 

 blue, similar in color to those of the Robin, but slightly lighter. They 

 measure about 1.05 x .73 inches. 



The Field Museum collection contains a series of sets of eggs of 

 this species taken in northern Illinois between May 26 and June 19.
