On September 11, 2026, the international community convened in Nairobi, Kenya, for the Global Flyways Summit, an event that served as the backdrop for the unveiling of a comprehensive report titled "State of the World’s Birds." This quadrennial publication, presented by BirdLife International, marks a significant departure from previous editions; for the first time, the document is exclusively dedicated to the complex, border-crossing phenomenon of bird migration and the vital ecological "flyways"—the aerial highways—upon which millions of birds depend for survival.
The summit concluded with the landmark signing of the Nairobi Flyways Declaration, a high-level political and institutional commitment to shift conservation efforts from localized, site-specific projects to a holistic, flyway-scale strategy. This transition is underpinned by a massive mobilization of capital, with development banks pledging over $6 billion in conservation finance since 2021 to support the restoration and protection of habitats spanning Africa, Asia, Europe, and the Americas.
The Alarming Reality of Avian Decline
The data presented in the 2026 report paints a sobering picture of global biodiversity. Current research confirms that 45% of all migratory bird species are in decline, with one in nine species now teetering on the edge of extinction. These figures represent more than mere statistics; they are biological indicators of failing ecosystems.
A particularly grim milestone highlighted in the report is the 2025 official declaration of the extinction of the Slender-billed Curlew. Last recorded in a Moroccan lagoon in February 1995, its loss is historic, representing the first confirmed extinction of a bird species on the mainlands of Eurasia and Africa in recent centuries. When coupled with the fact that six other migratory species have been lost or are suspected to have vanished in the last 150 years, the urgency of the Nairobi summit becomes clear.
The report identifies a hierarchy of threats, all of which are anthropogenic. The primary drivers include the catastrophic impact of invasive alien species, the rapid expansion and intensification of industrial agriculture, the accelerating pace of climate change, and the persistent, often unsustainable, practices of hunting and trapping. Species that rely on marine environments, coastal wetlands, and intact forest interiors are suffering the most severe population contractions, with shorebirds and seabirds emerging as the most vulnerable taxonomic groups.
Chronology and the Evolution of Flyway Conservation
For decades, international conservation efforts were fragmented, focusing on individual protected areas or single species. However, the realization that migratory birds are "sentinels of the planet" has forced a change in strategy.
- 1995: The last confirmed sighting of the Slender-billed Curlew in Morocco, marking the beginning of a long, unsuccessful search for the species.
- 2021: A surge in institutional interest begins as multilateral development banks start integrating biodiversity and flyway health into their lending frameworks.
- June 2026: The Global Environment Facility approves the Global Flyways Grant Mechanism, providing an initial $8.97 million in direct grants and unlocking over $100 million in co-financing.
- September 2026: The Global Flyways Summit in Nairobi launches the "State of the World’s Birds" report and the signing of the Nairobi Flyways Declaration.
This progression reflects a shift from reactive, emergency-based conservation to a proactive, systemic approach that views the entire migration route—from the Arctic breeding grounds to the non-breeding tropical stopovers—as a single, interconnected unit.
Financial Mobilization: A New Era of Funding
The scale of the financial commitment announced in Nairobi is unprecedented. The integration of biodiversity conservation into the core mandates of multilateral development banks suggests that flyway protection is no longer viewed as a peripheral environmental concern, but as a fundamental component of sustainable economic development.
The Asian Development Bank (ADB) has taken a leading role, pledging $3 billion over the next decade to safeguard at least 50 priority wetlands across the East Asian-Australasian Flyway. This initiative is expected to provide co-benefits for nearly 200 million people who rely on these ecosystems for water security, climate resilience, and food.
Similarly, in the Western Hemisphere, the Development Bank of Latin America and the Caribbean has committed between $3 billion and $5 billion through 2050. These funds are earmarked for the preservation of over 30 critical landscapes and seascapes. By embedding conservation into these massive financial instruments, the organizers hope to ensure that the "links" in the migration chain remain unbroken, preventing the collapse of entire ecological networks.
Official Responses and Institutional Perspectives
The summit brought together a diverse coalition of scientists, government ministers, and financial leaders, all emphasizing the need for cross-border cooperation.
Dr. Stuart Butchart, Chief Scientist at BirdLife International and a lead editor of the new report, emphasized the diagnostic role of migratory birds. "Migratory birds are sentinels, and their declines reveal growing pressure on the natural systems that sustain us," Dr. Butchart stated. "But the science is equally clear: conservation works. Coordinated action prevents extinctions and helps populations recover. The solutions exist; what is needed now is their implementation at a flyway scale."
Her Imperial Highness Princess Takamado, Honorary President of BirdLife International, echoed this sentiment by highlighting the geopolitical necessity of the agreement. "Migratory birds do not recognize borders," she noted. "They connect Asia to Africa, the Arctic to the tropics. The Nairobi Flyways Declaration acknowledges this reality—that it requires international cooperation and coordination to keep migratory birds safe."
Dr. Paul Matiku, Executive Director of Nature Kenya, spoke to the critical role of the Global South in this process. "African nations are not just stakeholders; we are stewards of solutions," Matiku said. "The birds that breed in Europe, Asia, and the Arctic depend on our wetlands, grasslands, and forests. The financial commitments made here ensure that the burden of conservation is shared equitably."
Implications: From Policy to Practice
The success of the Nairobi Flyways Declaration will ultimately depend on its implementation. The report provides a roadmap for this: when farming, fishing, and land-use practices are optimized across an entire migration route, populations have shown a remarkable ability to recover. The recovery of the Balkan population of the Egyptian Vulture serves as a primary case study for how multi-country, cross-border policy can halt and even reverse downward trends.
However, the analytical implications of the report are sobering. The loss of the Slender-billed Curlew serves as a warning that current efforts, while growing, have not yet reached the "tipping point" required to outpace the rate of habitat loss and climate-driven degradation.
The "Global Flyways Programme," developed by BirdLife International and its 125 partners across 120 countries, now faces the challenge of translating billions in pledged capital into on-the-ground action. This includes the restoration of millions of hectares of wetlands and the enforcement of protective regulations across thousands of miles of flight paths.
As the summit concluded, the message from the participants was one of cautious optimism. Martin Harper, Chief Executive of BirdLife International, summarized the mood by stating, "The State of the World’s Birds report is unambiguous: we are losing migratory birds at an alarming rate. But today’s Nairobi Declaration signals a turning point. We need everyone to step up and play their part—governments, business, and civil society. We must reverse the declines and save the wonder of migration."
The Nairobi Flyways Declaration is a monumental step toward recognizing that the health of the planet’s migratory birds is inextricably linked to the health of the global economy and human survival. Whether this commitment will be enough to prevent further extinctions in the coming decade remains the central question for policymakers and conservationists alike. For now, the global community has established a framework, a source of funding, and a shared acknowledgment that the sky is not a void, but a fragile, interconnected lifeline that requires urgent stewardship.
