Return of the Osprey: First Nesting Pair in 112 Years Hatches Chicks in Switzerland

A staggering 112 years of absence has officially ended as the Osprey reclaims its place in the Swiss skies. For the first time since 1914, a breeding pair has successfully hatched three chicks on Swiss soil, signaling a monumental victory for European conservation. This isn't just a biological milestone; it is a defiant reversal of a century-old tragedy. The species was once ruthlessly wiped out by poachers and egg collectors, leaving the lakes of Neuchâtel, Bienne, and Morat hauntingly empty of these apex predators. Today, that silence is broken. The return of the Osprey proves that nature can be restored when human intervention is bold and sustained. The pair took up residence on one of thirty artificial platforms meticulously placed by volunteers, transforming the Three Lakes region into a frontline of ecological rebirth. While the exact location remains a closely guarded secret to protect the birds, the impact of their presence resonates across the entire Alpine nation.

A massive logistics operation involving 66 imported chicks has finally paid dividends. Between 2015 and 2020, the association Nos Oiseaux executed a high-stakes translocation project, bringing young birds from Norway and Germany to Swiss aviaries. These birds were reared with zero human contact to preserve their wild instincts, a method that has surged in popularity across Europe since 1996. The data is clear: Ospreys possess a biological 'homing beacon,' returning to the region where they first took flight once they reach sexual maturity at age three or four. The male of this historic pair, identified by a numbered ring, is a direct product of this program. Meanwhile, his mate—an unringed female of unknown origin—represents the 'wild' success of the project, showing that the Swiss habitat is once again attractive to migratory populations. This synergy between human-assisted reintroduction and natural recruitment is the gold standard for modern wildlife restoration.

Three chicks emerged between May 25 and May 29, defying a spring that was notoriously cold and rainy. Project coordinator Wendy Strahm describes the success as 'exceptional,' especially considering the vulnerability of newborns to the damp Swiss Plateau climate. Two females and one male have not only survived but thrived, showcasing the resilience of the species. The female laid her first egg on April 19, following a winter spent apart from her mate in Africa. Their reunion and subsequent nesting success on the very first attempt is a statistical anomaly that has stunned experts. While most first-time parents struggle, this pair has demonstrated remarkable parental instincts. This success highlights the critical importance of the thirty nesting platforms installed by volunteers; without these secure elevated structures, the eggs would have likely fallen prey to ground predators or succumbed to the flooding risks of a harsh spring.

The celebration is tempered by a sobering reality: a staggering 80% mortality rate looms over these young migrants. As August draws to a close, the three chicks prepare to leave their Swiss birthplace for the arduous journey to Africa. This first migration is the ultimate test of survival, where they must navigate thousands of kilometers, unpredictable weather, and the threat of exhaustion. They will spend the coming years in the south before their instincts compel them to return to Switzerland in 2027 or beyond. The stakes could not be higher for Nos Oiseaux and the future of the Swiss population. However, the successful hatching of 2026 has established a blueprint for the future. If this pair returns next year, it will solidify the Three Lakes region as a permanent breeding colony. Switzerland now stands at a crossroads, moving from a country that once lost its biodiversity to one that actively and successfully fights to bring it back.
