Below is the most recent update for the Eastern Migratory Population of Whooping Cranes. During July, we have been busy monitoring chicks! 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. The International Crane Foundation produced this report.

Population Estimate

The current estimated population size is 68 (38 F, 28 M, 2 U). Fifteen of these 68 individuals are wild-hatched, and the rest are captive-reared. To the best of our knowledge, as of 1 August, there are about 56 in Wisconsin and one in Minnesota. 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.
