Below is the most recent update for the Eastern Migratory Population of Whooping Cranes. In the last month, Whooping Cranes have returned to Wisconsin, and some have started nesting! A huge thank you to the staff of the Fish and Wildlife Service, the Departments of Natural Resources of flyway states, the International Crane Foundation, and all 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. This report was produced by the International Crane Foundation.

Population Estimate

The current estimated population size is 77 (37 F, 37 M, 3 U). Seventeen of these 77 individuals are wild-hatched and the rest are captive-reared. To the best of our knowledge, as of 6 April, there are at least 67 Whooping Cranes in Wisconsin, two in Michigan, and one that was last seen in Indiana during March but is likely back in Wisconsin and has not yet been confirmed. The remaining birds’ locations have not been confirmed in the last month. Their last known locations (in the past month) are on the map below.
