I am part of a volunteer group for the Annual Midwest Crane Count, monitoring the wetlands and fields in Lake County, Illinois each year for sandhill cranes. In the pre-dawn hours, our eyes scan for any hint of movement. Our ears listen for a bugling sound. Our mission: Determine the abundance and distribution of sandhill cranes (Grus canadensis) in the Upper-Midwest United States.
The arrival of these large elegant birds in Lake County is a harbinger of spring. More migrate through this region every year, and an increasing number are deciding to nest here as well.
