Whooping Crane Update – April 1, 2017
Below is the most recent update for the Eastern Migratory Population of Whooping Cranes. During February, most Whooping Cranes began migration and at least one has returned to Wisconsin. A huge thank-you to the staff of Operation Migration, the Fish and Wildlife Service, the Department of Natural Resources, the International Crane Foundation, and all of 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 current maximum population size is 99 (45 F, 52 M, 2 U). As of 1 April, most Whooping Cranes have completed migration and are in Wisconsin. However, a few have not yet migrated and are in Illinois, Indiana, Arkansas, Tennessee, Alabama, and Florida. See map below. A few breeding pairs have begun nest building and a nesting update will be in next month’s report.
