Whooping Cranes 29-08 and 15-11 in Juneau County, Wisconsin
Below is the most recent update for the Eastern Migratory Population of Whooping Cranes. In the last month nesting season has come to an end, and chicks are starting to get big! 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 for the Whooping Crane Eastern Partnership.
The current estimated population size is 87 (40 F, 45 M, 2 U). This does not yet include wild-hatched chicks from 2019. To the best of our knowledge, as of 1 July, at least 71 Whooping Cranes are in Wisconsin, 4 are in Michigan, and 1 is in Minnesota. The remaining birds’ locations have not been confirmed in the last month. See map below.
