  •   

Whooping Crane W3-20, center, with parents 11-15 and 42-09 take flight in Adams County, Wisconsin.

Below is the most recent update for the Eastern Migratory Population of Whooping Cranes. In the last month, the youngest Whooping Crane chick has reached fledging age! 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 is produced by the International Crane Foundation.

Population Estimate

The current estimated population size is 81 (39 F, 39 M, 3 U). Seventeen of these 81 individuals are wild-hatched, and the rest are captive-reared. This now includes four of this year’s cohort of wild-hatched chicks who have fledged. To the best of our knowledge, as of 1 October, at least 72 Whooping Cranes are in Wisconsin, at least 2 are in Michigan (although possibly up to 4), and 1 in Illinois. The remaining birds’ locations have not been confirmed in the last month. See the map below.
