The Meadowlark is a common summer resident throughout Illi- 

 nois and Wisconsin, frequenting the open fields and prairies. A few 

 remain during the winter, but the majority arrive in March and leave 

 for the south again late in the fall. Its song is clear and rather 

 plaintive, and is subject to considerable variation. 



It breeds in May. The nest is built on the ground and is composed 

 of dry grass. The eggs are white, sparsely marked and speckled 

 with brown and lilac gray. They are from 4 to 6 in number, and 

 measure about 1.12 x .80 inches.
