Whooping Crane Eastern Population Update – October 2021

  •   
  •   

Whooping Crane females 80-19 and W18-20 in LaSalle County, Illinois. 

Below is the most recent update for the Eastern Migratory Population of Whooping Cranes. In the last month, we have released three captive-reared chicks and cranes are getting ready for migration! 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, 39 M, 4 U). Nineteen of these 81 individuals are wild-hatched, and the rest are captive-reared. To the best of our knowledge, as of 1 October, there are at least 63 Whooping Cranes in Wisconsin, one (possibly two) in Michigan and four in Illinois. 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.
