Below is the most recent update for the Eastern Migratory Population of Whooping Cranes. During April, birds have started nesting and the first two chicks have hatched! 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.
