The story of wildlife conservation is often told in losses—forests fading, species dwindling, habitats shrinking. And yet, every so often, nature surprises us with a comeback so spectacular that it restores our faith in what determined humans and resilient ecosystems can achieve together. Around the world, creatures once written off as doomed or even “lost forever” have re-emerged, thanks to a mix of science, serendipity, and sheer persistence. Some made their way back through careful breeding programmes. Others bounced back after decades of habitat restoration. A few, astonishingly, are now part of cutting-edge scientific attempts to undo extinction itself.
On the occasion of Wildlife Conservation Day, we take our time to revisit the stories of five such remarkable returns; proof that with patience, protection, and a little audacity, even the rarest species can step back into the wild.
Once a near-mythical presence in the Arabian deserts, the Arabian oryx came dangerously close to vanishing altogether. By the 1960s, climate shifts, long drought cycles, and the capture of wild individuals for private collections had devastated its numbers. Eventually, the oryx disappeared entirely from the wild.
But hope arrived in 1962, when a small group of oryx—just enough to form the basis of a breeding population—was carefully captured and transported to safety. Here began one of the world’s most successful captive breeding stories. Within a year, the Phoenix Zoo recorded its first birth, and soon, institutions such as the Los Angeles Zoo, San Diego Zoo, and the Gladys Porter Zoo joined the mission. Over decades, this international collaboration helped the species rebound from zero.
Today, the Arabian oryx roams its native landscape again. As of the latest 2016 assessment, about 1,200 individuals live in the wild, supported by a thriving managed population of 6,000 to 7,000 in conservation centres. From the brink of disappearance, the “desert ghost” now stands as a symbol of what global conservation can achieve.
How: Through a global captive-breeding programme launched in the 1960s, starting with a tiny founder group that multiplied across major zoos.
Where: Reintroduced across parts of Oman, the UAE, Saudi Arabia, and Jordan.
What: A wild population now estimated at around 1,200 animals, supported by 6,000–7,000 individuals in managed care.
A sight once considered heartbreakingly rare in Britain is now, happily, almost routine: the elegant sweep of a red kite drifting over farmland or village edges. In the late 1800s, these birds were nearly wiped out in the UK due to persecution and loss of habitat. Their recovery began much later—with a bold reintroduction initiative roughly 30 years ago.
Birds from Spain and Germany were brought in and released in the Chilterns, where they steadily regained a foothold. With steady support from organisations such as the RSPB and local conservation projects, the red kite population spread confidently across the country. Yorkshire, the East Midlands, and now large swathes of England and Wales once again report abundant sightings.
Today, red kites are among the UK’s fastest-growing bird species—a graceful reminder that raptors, too, can come home when landscapes and communities make space for them.
How: Reintroduced using birds imported from Spain and Germany, backed by long-term habitat protection and feeding support.
Where: First released in the Chilterns before spreading across England and Wales, including the East Midlands and Yorkshire.
What: One of the UK’s fastest-growing bird species, now a common countryside sight.
Tiny, elusive, and once written off entirely, the chequered skipper butterfly had vanished from England by 1976. Decades passed without a single wild sighting. Then, in a carefully planned move, conservationists decided to try the impossible. Butterflies were sourced from Belgium and released into Northamptonshire’s Fineshade Wood, a landscape restored to suit their delicate needs.
Slowly, signs of success emerged. Breeding was recorded. Populations stabilised. Surveys eventually counted more than 350 individuals, an astonishing revival for a species that had been absent for nearly half a century. This comeback stands as a testament to habitat management, scientific strategy, and the quiet magic of restoring ecosystems one plant, one clearing, and one wingbeat at a time.
How: Reintroduction using butterflies collected from Belgium, followed by careful habitat restoration in managed woodlands.
Where: Released primarily in Northamptonshire’s Fineshade Wood.
What: More than 350 butterflies recorded, proving stable breeding and successful species revival.
Some stories of revival look forward; others look back thousands of years. The moa, once the largest bird to walk New Zealand, vanished about six centuries ago after intensive hunting. Unlike other species on this list, the moa hasn’t returned—yet. But scientists are now exploring possibilities once relegated to science fiction.
Through DNA extraction from ancient remains and potential cloning technologies, researchers hope to understand whether the moa could one day be reintroduced to its former habitat. The rationale is compelling: restoring ecological balance, supporting native vegetation, and reviving a key part of New Zealand’s natural heritage. While the science remains experimental, each breakthrough in de-extinction research brings the moa a fraction closer to stepping into the light once more.
How: Experimental de-extinction research involving DNA extraction from ancient remains and theoretical cloning techniques.
Where: Genetic material is sourced from museum collections and archaeological sites across New Zealand.
What: Still in early scientific stages, with the long-term goal of potential ecological restoration in native grasslands.
Bright, brilliant, and heartbreakingly rare, the Spix’s macaw once vanished entirely from the wild. For over 20 years, the species survived only in captivity, with just around 20 individuals left at one point. But conservationists refused to give up. Breeding programmes expanded, habitats were restored, and the birds were slowly trained alongside wild macaws to prepare them for a life back under open skies.
In 2025, a milestone arrived: several Spix’s macaws were released into Brazil’s Caatinga region, re-establishing a wild population after decades of absence. Their struggles—popularised globally through the animated film Rio—are far from over. Habitat loss, predators, and environmental stress continue to pose threats. Yet the birds’ return remains one of the most uplifting conservation victories of the century, proof that coordinated global effort can breathe life back into even the rarest species.
How: Intensive international breeding programmes, behavioural training with wild macaw mentors, and habitat recovery.
Where: Released into Brazil’s Caatinga region, its original dry-forest home.
What: A growing rewilded population after more than two decades of complete disappearance from the wild.
These stories, each extraordinary in its own way, remind us that extinction is not always the end of the road. Sometimes, it becomes the beginning of a new chapter—one written with science, collaboration, and unshakeable optimism. In a world where ecosystems continue to face daunting challenges, the comeback of these animals shines like a promise: that with care and commitment, nature will find its way back.
1. How do animals come back from the brink of extinction?
Through a mix of captive breeding, habitat restoration, scientific research, and careful reintroduction into the wild.
2. Which species have made the most remarkable comebacks?
The Arabian oryx, red kite, chequered skipper butterfly, moa, and Spix’s macaw are prime examples of successful revival.
3. Can extinct species like the moa really be brought back?
Scientists are exploring de-extinction techniques such as DNA cloning, but it remains experimental with long-term ecological goals.
4. Why is conservation important for these species?
Protecting habitats and supporting populations ensures biodiversity, maintains ecosystems, and allows species a chance to recover.
5. How can the public support wildlife revival efforts?
Through supporting conservation organisations, respecting wildlife habitats, and spreading awareness about the importance of protecting endangered species.
