In 2017, conservationists watching Serbia's skies could find just one breeding pair of Eastern Imperial Eagles in the entire country. By 2025, there were 19 — and 14 chicks hatched in a single season. It is one of the most dramatic raptor recoveries in European conservation history.
The Eastern Imperial Eagle (*Aquila heliaca*) is a large, powerful bird of prey once revered as a royal symbol across Central and Eastern Europe. It was nearly wiped out by habitat loss, poisoning, electrocution on power lines, and nest disturbance. By the early 2000s, its range had collapsed to fragments of its former territory, with Serbia teetering on the edge of losing the species entirely.
**From the Brink: One Pair Left**
In 2017, Serbia's Bird Protection and Study Society (BPSSS) documented just a single breeding pair within the country's borders. That solitary nest represented both the nadir of the species' decline and the fragile beginning of something extraordinary.
'It was a deeply concerning moment,' said one of the BPSSS monitoring team. 'One pair means one bad breeding season — a failed nest, a poison bait, a power line collision — and the species is functionally gone from Serbia.'
What followed was a methodical, multi-pronged rescue operation. Rangers installed nest platforms in areas lacking suitable old-growth trees (destroyed by intensive agriculture). They worked with farmers to address concerns about eagles and livestock. They identified and replaced dangerous power line infrastructure that caused electrocutions. And they launched community education campaigns that fundamentally shifted local attitudes towards these birds.
**19 Pairs — and 14 Chicks in 2025**
By 2025, those efforts had translated into 19 confirmed breeding pairs across Serbia. In that year alone, 14 Eastern Imperial Eagle chicks hatched and fledged successfully — more than the entire country's breeding population just eight years earlier.
The turnaround has been powered in part by the EU-funded **PannonEagle LIFE** project, a cross-border collaboration involving Serbia, Hungary, Slovakia, the Czech Republic, and Austria. By coordinating conservation actions across the eagle's shared migratory range — particularly in the Pannonian Basin — the project has addressed threats that no single nation could tackle alone.
The species has also made gains in Hungary and Slovakia, where decades of similar work have stabilised and slowly grown populations that were once in freefall.
**The Story of Felix**
The recovery is not without its heartbreaks. In 2025, a chick named Felix was ringed and fitted with a satellite transmitter to track his migration south. He made it to Lebanon — and was then captured by illegal wildlife traffickers.
The response was immediate. A fundraising campaign was launched to repatriate Felix, and international pressure led to his transfer to a wildlife shelter. His story became a rallying point that brought global attention to the species' plight — and its comeback.
**Still Fragile, But Facing Forward**
Conservationists are careful to note that 19 pairs is still a precarious number. The Eastern Imperial Eagle remains classified as Vulnerable on the IUCN Red List. The scarcity of suitable old, tall trees continues to limit nesting sites, and the species' slow adaptation to artificial platforms means progress is painstaking.
But the trajectory is unmistakable. The techniques developed — community engagement, power line retrofitting, artificial nesting platforms, cross-border monitoring — are being shared and replicated across Central Europe.
'Eight years ago we had one pair. Now we have nineteen, and the number is still going up,' the BPSSS team reported. 'This is what happens when conservation is done patiently, collaboratively, and at scale.'
The Eastern Imperial Eagle — once nearly erased from Serbia's skies — is coming back. One nest at a time. 🦅
