The Venetian Lagoon has no word for flamingos in its local dialect—until recently, there was simply no need for one. But the pale pink birds, called "fenicotteri" in Italian, are now arriving in record numbers that have transformed this sprawling 550-square-kilometer expanse of water and mudflat into one of Europe's most vital winter refuges for the species. Last year, nearly 24,000 flamingos descended on Venice's lagoon, an astonishing surge of 8,000 birds from the previous year and a testament to both the lagoon's recovering health and the expanding range of a species once nearly absent from the region.
When flamingos first started appearing in Venice in the early 2000s, they were rarities—occasional visitors to the fishing valleys and mudflats in the lagoon's furthest reaches, nowhere near the canaled historic center that millions of tourists traverse each year. Their arrival puzzled locals. But ornithologist Alessandro Sartori, who surveys the lagoon weekly by boat, recognized it as a sign of something profound: the lagoon's suitability as a feeding ground and the broader expansion of the European flamingo's range northward. "The numbers that position the Venetian Lagoon as one of the most important wintering spots in its entire habitat range," Sartori observed, underscore how dramatically circumstances have shifted.
What makes this resurgence particularly striking is that it coincides with deliberate efforts to heal a lagoon that had been ravaged by decades of industrial and human activity. The Venetian Lagoon was originally nearly half salt marsh—those shallow, nutrient-rich wetlands that flamingos depend on. Today, that figure has plummeted to just 7 percent, with roughly half of what remains having been artificially reconstructed. The damage accelerated in the 1960s when shipping channels were dredged to accommodate the Marghera industrial port, triggering widespread erosion and sediment loss that continues to reshape the landscape.
Enter the EU-backed WaterLANDS project, a €23.6 million, five-year initiative to restore wetlands across Europe. Jane da Mosto, executive director of We Are Here Venice and the local partner in the project, frames the work in stark terms: "Venice is now on a trajectory to becoming a marine bay." The salt marsh reconstruction effort, she explains, represents a chance to reverse that trajectory. The team is planting species designed to reduce erosion and increase resilience while researching ways to boost biodiversity more broadly. Already, recent surveys of reconstructed mudflats reveal stray pink feathers and distant flocks of flamingos—quiet signs that the birds are claiming this recovering landscape.
More than 90 percent of last year's flamingo population concentrated in the northern lagoon, where natural salt marsh remains abundant. A secondary project to reconstruct wetlands in the isolated southern lagoon could eventually disperse the birds more evenly across the water, drawing them away from areas where they compete with traditional fishing activities. Previous nesting attempts in 2008 and 2013 failed due to violent hail and other setbacks, but as habitat expands and stabilizes, the possibility of a permanent, self-sustaining Venetian flamingo colony edges closer.
The broader significance extends beyond the birds themselves. Wetland restoration captures carbon dioxide, mitigates rising sea levels, and signals a shift from decades of lagoon degradation. For Venice—a city synonymous with environmental vulnerability—the sight of thousands of flamingos winging across its waters has become an emblem of what recovery can look like when human effort aligns with ecological necessity.
