Whooping Crane 16-11 (Grasshopper) with chicks 73-18 and 74-18 have begun migration and are in Jasper County, Indiana.

Below is the most recent update for the Eastern Migratory Population of Whooping Cranes. In the last month, Whooping Cranes have left Wisconsin and many have reached their wintering locations, while many birds are still on the move! A huge thank-you to the staff of the Fish and Wildlife Service, the Department of Natural Resources, the International Crane Foundation, and all of the volunteers who help us keep track of the cranes throughout the year. We appreciate your contribution to the recovery of the Whooping Crane Eastern Migratory Population.

Population Estimate

The current estimated population size is 101 (45 F, 53 M, 3 U). As of 27 November, approximately 19 Whooping Cranes are in Illinois, 33 are in Indiana, 1 may still be in Michigan, 7 are in Kentucky, 5 are in Tennessee, 11 are in Alabama, and 1 is in Georgia. The remaining birds’ locations have not been confirmed in the last month or they have left Wisconsin but haven’t yet been confirmed further south. See map below.
