The Lark Sparrow is a prairie species that is year by year extending 

 its way into the former forest area. In 1861 it made its first appear- 

 ance in Ohio, and about the same time appeared in Ontario. In 1879 

 it was common throughout central Ohio, but both north and south 

 of there it was rare. In Indiana it is most numerous through the 

 central part of the State. It was rather rare until recently in southern 

 Indiana, and is still scarce in many localities northward. Everywhere
