For the first time, awhooping crane chick has hatchedat the Smithsonian Conservation Biology Institute (SCBI) in Front Royal, Virginia.
On Friday, the Virginia facility announced that the whooping crane, which is one of the most endangered species of crane in the world, hatched on May 26 and has been “thriving” ever since.
The International Crane Foundation and Necedah National Wildlife Refuge found the egg abandoned in a wild nest in Wisconsin and passed the discovery on to SCBI, so the institute’s bird team could take the arriving crane under its wing.
SBCI’s 16-year-old female whooping crane Tehya and its 25-year-old male whooping crane Goliath served as surrogate parents for the chick and have been “protective and attentive to its needs” both inside the egg and out.

Tehya and Goliath recently bred and produced two eggs of their own, but both were infertile.
“As part of the Whooping Crane Reintroduction Partnership, the Association of Zoos and Aquariums' Species Survival Plan (SSP) for Whooping Cranes selected Tehya and Goliath as the surrogate parents because the wild egg was laid around the same time as the pair’s infertile eggs, so the incubation period aligned,” SCBI shared in a release. “While keepers awaited the arrival of the wild egg, they discarded the infertile eggs and provided Tehya and Goliath with a fake egg so they could continue to practice their natural parenting behaviors.”
“Just prior to hatch, keepers switched Tehya and Goliath’s fake egg for the fertile one,” the statement continued. “When the colt hatched, both parents immediately began caring for it. Keepers and veterinarians are allowing the family to bond without interference.”
Whooping cranes are endangered due to habitat destruction, hunting, poaching, climate change, natural disasters, and oil spills. The species declined to about 22 birds in 1941, but with conservation efforts, numbers have risen to about 700 in the wild and 140 in human care, according to SCBI.
