In the late 19th century, bearded vultures were systematically exterminated across the Alps. Farmers feared them, rumours circulated that they carried off children, and by the 1900s they had been completely wiped out from one of Europe's most iconic mountain ranges.
In 1986, a reintroduction programme began. It was patient, expensive, and uncertain. And now, nearly 40 years later, it has produced something extraordinary: 118 wild bearded vultures soaring over the Alps, more than 100 breeding pairs confirmed, and a self-sustaining wild population for the first time since the species was locally extinct.
The Oldest Wild Bearded Vulture Ever Recorded
The most remarkable discovery came in late 2025, when researchers identified Balthazar — a bird first released into the wild in 1988 — alive and apparently healthy at over 37 years old. He had been presumed dead for years. Finding him confirmed something scientists had long suspected but never documented: bearded vultures in the wild can live for decades.
Balthazar is now the oldest recorded bearded vulture in the wild. His survival — through alpine winters, competition, and the hazards of mountain flying — represents extraordinary longevity for a large raptor. He is, in a very real sense, a living monument to the recovery programme itself.
A Programme Built on Patience
The Bearded Vulture Reintroduction Programme, coordinated by the Vulture Conservation Foundation, has released more than 260 birds across the Alps over four decades. Each bird was raised in captivity and painstakingly acclimatised before release. Recovery has been slow by design: bearded vultures don't breed until age 7 or 8, meaning each generation takes years to establish.
The 2025 milestone — passing 100 wild breeding pairs — marks the point at which the Alpine population is now considered self-sustaining. These birds are reproducing, raising chicks in the wild, and doing so without ongoing human support. The programme is effectively complete.
Nature's Bone-Crackers
Bearded vultures, or lämmergeier, are unlike other vultures. They feed primarily on bone marrow, dropping bones from height onto rocks to crack them open. Their digestive system is acid-strong enough to dissolve bone entirely. They are ecological specialists, evolved over millions of years to fill a niche nothing else occupies: the final stage of carcass consumption in mountain ecosystems.
Their absence from the Alps left that niche empty for nearly a century. Their return is not just a conservation win — it is the restoration of a complete ecological function.
In the Pyrenees, bearded vulture recovery is also underway. The Spanish population has been growing for years. The programme that seemed impossibly ambitious in 1986 — restoring an extinct species to one of the world's most visited mountain ranges — has worked.
