The spring migration of whooping cranes is underway, and wildlife officials say they are seeing more progress in efforts to reintroduce the species to eastern North America.
The work is being led by the Whooping Crane Eastern Partnership, an international coalition of public and private groups.
It says two chicks that hatched in the wild in Wisconsin last year spent the winter with their parents in Indiana and have now returned. The group says this marks the first time whooping crane chicks born in the wild have completed a migration cycle as part of the restoration.
The group says there were 84 whooping cranes confirmed in central Wisconsin as of April 3. There are 108 total in the wild in eastern North America.
