The whooping crane is an endangered species of crane native to North America. Their population declined significantly during the 20th century primarily due to habitat loss and overhunting. By 1941, there were only 21 whooping cranes left in the wild. Since then, conservation efforts have helped increase their numbers, but whooping cranes remain endangered with only about 500 total birds today.
The recovery of the whooping crane has been a decades-long effort by multiple conservation organizations and wildlife agencies. Many biologists have devoted their careers to saving this iconic bird. So who are the key figures that have become synonymous with whooping crane conservation?
Ernest F. Staffeldt – Pioneer of the Whooping Crane Breeding Program
One of the most important early conservationists for the whooping crane was Ernest F. Staffeldt. He was recruited by Robert Porter Allen of the National Audubon Society in 1947 to lead the whooping crane breeding and reintroduction program at the Audubon Center in Louisiana. At that time, with so few whooping cranes left, breeding the birds in captivity and releasing them into the wild was seen as the only hope for the species.
Staffeldt pioneered techniques for hatching and raising whooping crane chicks in captivity. This included everything from artificial insemination of breeding birds to using puppets and costumes to prevent newly hatched chicks from imprinting on their human caregivers. Staffeldt led the whooping crane program at the Audubon Center for nearly 20 years and was instrumental in providing the birds that would keep the species from going extinct entirely.
Highlighting Staffeldt’s Achievements
- Led the whooping crane breeding program at Audubon Center from 1947 to 1966
- Developed methods for artificial insemination and captive rearing still used today
- Oversaw the rearing and release of the first whooping cranes into the wild in 1966
- Worked alongside other pioneers like Robert Porter Allen and Austrian ethologist Konrad Lorenz
Later in his career, Staffeldt moved to the U.S. Fish and Wildlife Service’s Patuxent Wildlife Research Center to continue his work breeding whooping cranes. He passed away in 1970, but the techniques he developed at Audubon formed the foundation of the whooping crane revival for decades to come. Staffeldt’s pioneering efforts in captive breeding saved the whooping crane from extinction.
George Archibald – Co-founder of the International Crane Foundation
In 1973, a young biologist named George Archibald co-founded the International Crane Foundation (ICF) with colleague Ron Sauey. This organization was dedicated to the conservation of the world’s 15 crane species, including the endangered whooping crane.
Archibald had studied cranes extensively for his graduate research and fully devoted himself to saving these magnificent birds. Under his leadership, the ICF led groundbreaking work in captive breeding, reintroduction, habitat protection, and education programs. Their whooping crane efforts boosted the wild population from fewer than 60 birds to over 500 today.
Archibald’s Major Accomplishments
- Co-founded the International Crane Foundation in 1973
- Pioneered captive breeding methods to increase whooping crane numbers
- Helped establish new wild crane flocks through reintroduction programs
- Protected vital crane habitats around the world
- Raised global awareness through extensive education and research
Archibald served as President of the ICF until 2000, continuing to advance crane conservation worldwide. He received numerous honors for his work, including the prestigious Tyler Prize for Environmental Achievement in 1987. Now in his 80s, Archibald remains active at the ICF as an influential advocate for protecting rare and endangered cranes.
Tom Stehn – Longtime Leader of the Recovery Program
As whooping crane numbers slowly increased in the wild, managing and monitoring the growing flocks became an immense task. For over 30 years, biologist Tom Stehn served as the government’s point person on the species’ recovery.
Stehn started working with whooping cranes in 1979 as the expert for the U.S. Fish and Wildlife Service’s Aransas National Wildlife Refuge, the winter home for the sole migratory whooping crane flock. In 1980, he took over as regional recovery team leader. Stehn coordinated efforts between government agencies, nonprofits, and landowners to continue returning whooping cranes to the wild.
Highlights of Stehn’s Career
- Whooping crane recovery team leader from 1980 to 2011
- Oversaw monitoring of the Aransas-Wood Buffalo flock for over 3 decades
- Worked to protect cranes from threats like collisions, pollution, habitat loss
- Leader in developing policies and conservation plans for the species
- Retired after Aransas NWR was critically damaged by droughts
Some major accomplishments during Stehn’s tenure included establishing a new migratory flock in Florida, releasing captive-bred cranes into Louisiana wetlands, and closely tracking whooping crane reproduction and mortality. He retired in 2011 after severe droughts depleted the marshes of Aransas NWR, but his many years of service were crucial for bringing back the iconic cranes.
Other Notable Contributors
While the above three men had especially prominent roles, whooping crane recovery has been a collaborative effort involving many biologists and conservationists over the decades. A few other notable names:
- Robert Porter Allen – Ornithologist who recruited Staffeldt and pushed for action to save the whooping crane starting in the 1940s
- Konrad Lorenz – Austrian zoologist who pioneered imprinting research; studied captive whooping cranes at Audubon Park in the 1950s/60s
- Brian Johns – Canadian biologist who oversaw whooping crane policy and the Wood Buffalo National Park captive breeding flock for 30 years
- Joe Duff – Led Operation Migration’s work reintroducing migratory cranes with ultralight aircraft from 2001 to 2017
- Liz Smith – Current whooping crane coordinator for the U.S. Fish and Wildlife Service andSpecies Recovery Director at ICF
This list is just a sampling of the many biologists, wardens, veterinarians, pilots, and volunteers who have collectively brought the whooping crane back from the brink over the past 75 years through captive breeding and release programs.
The Future of the Whooping Crane
The dedicated efforts of these experts and others have made the outlook for whooping cranes much brighter today compared to 1940s, when the species was on the knife’s edge of extinction. From 15 cranes in the 1940s, wild whooping crane numbers have increased to over 500 total birds across four flocks today.
However, the species is still considered endangered and faces ongoing threats to its recovery. These include:
- Habitat destruction
- Climate change impacts
- Collisions with man-made structures
- Pollution and contaminants
- Disease outbreaks
Maintaining stable captive breeding programs and restoring secure wetland habitat will remain essential to safeguarding the whooping crane into the future. The conservation community owes an immense debt to the whooping crane guy pioneers like Ernest Staffeldt, George Archibald, and Tom Stehn who believed in and fought for the revival of these magnificent birds over decades when their outlook was bleakest.
While numbers have rebounded, whooping cranes are still far from a fully recovered population. Their habitat faces increasing pressures across their breeding and wintering grounds.Continuing research, habitat protection, public education, and careful stewardship will be required to keep the species on the path to recovery. The work of conserving the whooping crane remains unfinished, but thankfully far from the desperate situation Staffeldt, Archibald, and others faced when trying to pull the cranes back from the brink several decades ago.

Whooping Crane Conservation Challenges Ahead
The almost miraculous recovery of the whooping crane from the brink of extinction is an inspiring conservation success story. However, as the total population has passed 500 birds, biologists are continuing to work on addressing ongoing and future challenges facing the species’ recovery. Some of the main areas of focus looking ahead include:
Securing Adequate Habitat
Whooping cranes require large open wetland areas for breeding, migration stopovers, and wintering habitat. These sites continue to face pressures from development, oil and gas drilling, water diversion projects, and drainage efforts. Conservation groups are working to secure formal habitat protections and acquire or restore additional wetlands through purchase and partnerships.
Managing Genetic Health
The small founding population and isolation of flocks has created some genetic bottlenecks. Managers are now recommending limited artificial insemination and transfers between captivity and the wild to increase genetic diversity. This will strengthen future reproductive health and resiliency.
Bolstering Captive Flocks
Captive breeding flocks act as a genetic repository and have been used to supplement wild whooping cranes for releases. Facilities are expanding capacity and improving husbandry techniques to continue producing ample birds for introduction.
Increasing Reintroductions
Releasing captive-reared juveniles using costumed handlers or ultralight aircraft has been very successful in establishing new flocks. Managers are working to increase reintroductions to build up wild numbers to a sustainable level across multiple flocks.
Reducing Mortality
Collisions with power lines causes significant whooping crane deaths, especially among young birds. Conservationists are seeking to bury or re-route lines, install markers, and create safer flight paths. Other mortality issues like disease, predation, and shooting are also being addressed.
Public Education
Outreach programs help ensure wetlands protection and reduce disturbance of cranes. Education also builds continued public interest and support for completing the whooping crane’s recovery journey.
The whooping crane remains one of the rarest birds in North America. Ongoing conservation efforts across scientific disciplines, governments, nonprofits, landowners, and the public will be needed to secure the species. While not yet out of the woods, the outlook for the iconic whooping crane is far brighter thanks to the foundation laid by dedicated biologists over the past 75 years.
