Baraboo, Wis. – A reintroduction success story took place this past weekend, when a Whooping Crane family returned to Wisconsin, flown North courtesy of Windway Capital Corp. of Sheboygan, Wisconsin.

The family will call the marsh its home until they migrate South on their own again this fall. They will be monitored by the staff of the International Crane Foundation, as part of the Whooping Crane Eastern Partnership (WCEP).

The family spent their first night at Horicon Marsh in a temporary enclosure. They were released the following morning.

“This story – still ongoing – is really an enormous success for Whooping Cranes, and reintroduction science, due to the experimental nature of this pairing,” said International Crane Foundation Crane Research Coordinator Anne Lacy.

The patriarch of the family has a colorful history. Grasshopper, or 16-11, was raised at the International Crane Foundation through the Direct Autumn Release Program. He was released at Horicon National Wildlife Refuge in 2011.

In 2015, the International Crane Foundation discovered that Grasshopper had paired with a Sandhill Crane female at Horicon National Wildlife Refuge in eastern Wisconsin. “Wisconsin’s current Whooping Crane population is so small, we really didn’t like this pairing. We prefer that he create more Whooping Cranes, of course!” explained Lacy.

This pair had a hybrid chick in the spring of 2016. As this was not in the plans of WCEP, the chick was captured and brought to the International Crane Foundation, where he happily resides today in Crane City.

Grasshopper is back in Wisconsin!

In hopes of re-pairing Grasshopper with a female whooping crane, he was relocated in the fall of 2016 to White Oak Conservation, a private, accredited facility in Yulee, Florida. There, the partnership undertook a never-before-attempted experiment – trying to create a new pairing and return the new pair back to the wild.

The Partnership choose a more appropriate mate for Grasshopper, a female Whooping Crane named Hemlock, or 18-12. She was costume-reared at The International Crane Foundation, but not released as a chick for health reasons that have now been resolved.

“The plan was to give the pair space in a safe setting to see if they would become a couple,” said Lacy. “If they were successful as a breeding pair, it would be one more step forward in bolstering the wild population.”

As cranes are famous for being very particular in choosing a mate, the WCEP partnership waited with fingers crossed, to observe what would happen after introducing the pair. “Thankfully, it didn’t take long for them to exhibit friendly behaviors,” recalled Lacy. “Within the year they were unison calling together and flying circles around their large enclosure.”

Just as cranes are fussy when it comes to their partners they are renowned for their mate fidelity once they have forged that bond. This spring, their bond was strong enough for Hemlock to lay eggs. “Our expectations were met and then some,” Lacy said. “Not only did Hemlock lay two eggs, they were both fertile.” Thirty days later, the first two Whooping Crane chicks of 2018 hatched.”

This story now continues on the Wisconsin landscape, where researchers hope the family will acclimate to successfully living in the wild.

“The successful release of this crane family is a testament to the commitment and cooperation of the partners involved, resulting in positive outcomes and support for the long-term recovery of the whooping crane,” said Steve Shurter, CEO of White Oak Conservation.

“For an endangered species like the Whooping Crane, every individual – and their ability to reproduce – is critical to the survival of the species,” explained Lacy. “That’s why we go the extra mile to help with their fragile recovery.”
