There are six subspecies of North American sandhill cranes: the lesser (Grus canadensis canadensis), greater (G. c. tabida), and Canadian (G. c. rowani) sandhill cranes are migratory, and the Mississippi (G. c. pulla), Florida (G. c. pratensis), and Cuban (G. c. nesiotes) sandhill cranes do not migrate (Van Horn et al. 2010). Greater sandhill cranes are divided into five geographic populations: Prairie, Rocky Mountain, Eastern, Colorado River Valley and Central Valley (Meine and Archibald 1996). The Eastern Population (EP) of sandhill cranes range extends from the southern parts of Ontario to central Florida (Figure 1). The primary EP breeding range extends across the Great Lakes region and includes Michigan, Wisconsin, Minnesota, and Ontario (Dubovsky 2016). Recent trends show expansion in all directions of the EP breeding range (Van Horn et al. 2010).
