Below is the most recent update for the Eastern Migratory Population of Whooping Cranes. In the last month, three more wild-hatched chicks have fledged! 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 78 (37 F, 37 M, 4 U). This now includes this year’s four wild-hatched chicks. Nineteen of these 78 individuals are wild-hatched and the rest are captive-reared. To the best of our knowledge, as of 1 September, there are at least 68 Whooping Cranes in Wisconsin and two in Michigan. 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.

2021 Wild-hatched Cohort

Nesting season is complete and there were 14 chicks confirmed to have hatched and up to four are still alive (see below).

W2-21 (U) hatched to parents 3-14 and 4-12 in Green Lake County, WI, at the beginning of May and fledged in July.

W10-21 (U) hatched to parents 12-03 and 12-05 at Necedah National Wildlife Refuge in Juneau County, WI, and fledged mid-August.

W11-21 (M) hatched to parents 36-09 and 18-03 at Necedah National Wildlife Refuge in Juneau County, WI, and fledged mid-August.
