Whooping Crane Eastern Population Update – September 2020

  •   
  •   

Whooping Crane pair 4-12 and 3-14 in Green Lake County, Wisconsin this summer.

Below is the most recent update for the Eastern Migratory Population of Whooping Cranes. In the last month, another 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 (38 F, 38 M, 5 U). Sixteen of these 81 individuals are wild-hatched and the rest are captive-reared. This total now includes three of this year’s cohort of wild-hatched chicks who have fledged but does not yet include W18-20 who has not yet fledged. To the best of our knowledge, as of 1 September, at least 73 Whooping Cranes are in Wisconsin, at least 1 is 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.
