Whooping Crane 59-13 (Latka) was spotted with her mate in St. Croix County, Wisconsin, earlier this spring.

Below is the most recent update for the Eastern Migratory Population of Whooping Cranes. Nesting season in Wisconsin is in full swing! 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 was produced by the International Crane Foundation.

Population Estimate

The current estimated population size is 77 (38 F, 37 M, 2 U). Seventeen of these 77 individuals are wild-hatched and the rest are captive-reared. To the best of our knowledge, as of 1 May, there are at least 68 Whooping Cranes in Wisconsin, two in Michigan, and one 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.
