This well known species is a very common summer resident in 

 Illinois and Wisconsin and breeds in suitable localities. It is often 

 seen along the banks of rivers and ponds. The nest is at times a 

 slight structure of grass, while at others it is a mere depression in the 

 ground with a little loose grass and leaves.
