Once widespread across Europe, North Africa, and the Middle East, the distinctive northern bald ibis vanished from European skies. Luckily in an extraordinary twist of fate, this bird is making a comeback. But not without a human-led detour! These birds lack the instinct to migrate without the guidance of their wild elder birds. Now it’s up to the remarkable efforts of scientists and conservationists to teach these birds to fly along long-lost migration routes.
A Mysterious Avain Heartthrob
The northern bald ibis is quite the looker! Its iridescent black-green plumage, bald red head, and long curved beak let these avians stand out in the world of ornithology. Also known as a Waldrapp in German, the bird became a delicacy, leading to its disappearance from European skies. They actually faced near-extinction by the 17th century! Classified as “critically endangered,” the bird’s presence in Europe vanished for over a decade. Their only lifeline was a few colonies elsewhere in the world that managed to survive. Luckily this dire situation brought a group of dedicated conservationists and scientists destined to bring these magnificent birds back from the brink of immanent birdpocalypse.
Assemble The Waldrappteam
In 2002, a conservation and research group led by biologist Johannes Fritzin Austria in Austria, initiated a groundbreaking project. The Waldrappteam’s mission was to reintroduce the northern bald ibis to its former European habitats. It was the very first attempt to reintroduce a continentally extinct migratory bird species. Starting from scratch, they managed to increase the Central European population of northern bald ibises to almost 300 birds. The northern bald ibis moved from “critically endangered” to “endangered,” marking a significant milestone in conservation efforts.
Upside Down Or Turn Around Flight
While the breeding program was successful, the Waldrappteam faced an unexpected hurdle. The newly introduced northern bald ibises displayed a natural urge to migrate, but they seemed to be grounded on the airbase with no boarding instructions. Without the guidance of their wild-born elders, these birds were at a loss when it came to navigation. At first, all reintroduction attempts failed since the birds flocked in different directions, unable to find suitable wintering grounds like Tuscany, Italy.
Featherless Foster Parents
Soon the Waldrappteam had to take on the unconventional role of foster parent flight instructor. They developed a unique approach to imprint the young birds. By removing chicks from their breeding colonies when just a few days old and raising them in aviaries overseen by human foster parents, they create a bond crucial for their future migration success. Talk about a literal found family!
Imprinting isn’t Only For T-shirts
Barbara Steininger, a dedicated member of the Waldrappteam, embraced her role as a bird momma with open arms. She and her colleagues went beyond caretaking even interacting with the young ibises to build trust and familiarity. This process was designed to ensure that the birds would follow their human guides during the migration journey. Which I think is quite impressive considering human children barely follow their parents without candy or a firm hand holding to motivate them.
The Skies Less Traveled
Using a microlight aircraft that resembles a flying go-kart with a giant fan and a yellow parachute, the team guides the birds along their migration route. Foster parents sit on the back of the aircraft, waving and shouting encouragement through a bullhorn as they soar over alpine meadows and foothills. Johannes Fritz stated that he drew inspiration from the pioneering work of Bill Lishman, known as “Father Goose.” Lishman’s 1988 ultra-light plane experiment, which proved effective in teaching Canadian geese to fly alongside it, opened the door for similar methods in guiding other endangered species. This unusual strategy proved the possibility of human-guided migration as a conservation technique, which would later inspire the film “Fly Away Home.” Who would have thought humans and birds could flock together?
Traveling Home For Ibis-mas
In 2011 the Waldrappteam’s perseverance paid off. Shaking off its early flight jitters, the first bird independently migrated back to Bavaria from Tuscany, marking the beginning of a new era for the northern bald ibis in Europe. As more birds undertake the journey of over 342 miles each year, they gradually rebuild their migratory population. This led the team to set a new ambitious goal of increasing the Central European population to more than 350 birds by 2028. After all, we’re aiming for a self-sustaining community!
Improvise, Adapt And Overcome
Unfortunately, it’s not all smooth sailing from here. Climate change, our old enemy, has brought about new challenges. Temperature changes caused the birds’ migration patterns to begin to shift, leading to flight delays. Since departures now occur later in the season the ibises have to brave the Alps colder, more dangerous weather conditions. Without the benefit of the warm air currents known as thermals, they’re struggling to conserve energy during flight. A bold decision by the Waldrappteam had to be made in 2023. The team decided on a new migration route from Bavaria to Andalusia in southern Spain. Although this new route presents its own set of complications, it offers a safer passage for the birds. This 2024 migration has a route spanning approximately 1,740 miles. This is 186 miles longer than the previous year! With clear blue sky and excellent tailwinds, the crew recently guided 36 birds successfully, showing a promising start for this year’s migration attempt. But will it last?
Birds Beyond the Northern Bald Ibis
While the focus of this remarkable project is the northern bald ibis, the hope it brings reaches far beyond a single species. Johannes Fritz and his team view their work as a pioneering effort that could pave the way for the conservation of other threatened migratory species. Their approach is creating a blueprint that could be adapted to help numerous bird species facing similar struggles. As climate change continues to look like a boss battle against migratory species, the lessons learned from this project may prove invaluable for safeguarding the future of countless directionless birds.
