The Mourning Dove is a common summer resident in northern 

 Illinois and Wisconsin and a few remain during the winter. In south- 

 ern Illinois it is a permanent resident. The mournful note of the 

 male suggests its name. 



The nest is a mat of twigs usually in a tree, occasionally on the 

 ground. The eggs are white, two in number, and measure about 1.05 

 x .85 inches. The Field Museum collection contains a series of sets 

 of eggs ot this species taken in northern Illinois, between May loth 

 and June 29th.
