Birds are running out of places to land: 45% of migratory bird species now in decline.
BirdLife International today has published the State of the World’s Birds at the Global Flyways Summit in Nairobi and this impacts Ireland too.
BirdLife Partners, NGOs, governments and financial institutions sign the Nairobi Flyways Declaration, as development bank initiatives spanning Africa, Asia, Europe and the Americas move into delivery.
BirdLife International today launched the State of the World’s Birds report at the Global Flyways Summit, co-hosted by Nature Kenya. Published every four years, this is the first edition devoted to migratory birds and the flyways they depend on.
The summit also saw key stakeholders including governments, scientists, NGOs, conservationists and financial institutions sign the Nairobi Flyways Declaration, committing to stepping up efforts and cooperation to protect migratory birds and their habitats across borders, alongside more than $6 billion in conservation finance being mobilised by development banks since 2021.
Together, these milestones signal a step-change in coordinated global response for flyway conservation.
State of the World’s Birds: the findings
The report’s findings are stark, 45% of migratory bird species are in decline. One in nine is threatened with extinction. The 2025 extinction of the Slender-billed Curlew, last recorded at a Moroccan lagoon in February 1995, marks the first global bird extinction in mainland Eurasia and Africa in recent centuries, with six other migratory species confirmed or suspected to have been lost in the last 150 years.
Species dependent on marine habitats, forests and coastal wetlands are faring particularly poorly; seabirds and shorebirds are among the most threatened.
Yet the report also documents hope. These declines stem from well-understood, human-caused factors: invasive species, agricultural intensification, climate change, and unsustainable hunting. When farming, fishing and land practices are addressed across a whole migration route, rather than at single sites, bird populations respond.
For example, multi-country action for Egyptian Vulture has halted the decline of the Balkan breeding population.
“Migratory birds are sentinels, and their declines reveal growing pressure on the natural systems that sustain us.
“But the science is equally clear: conservation works, with co-ordinated action preventing extinctions and helping populations recover. The solutions exist: what is needed now is their implementation at flyway scale.”
Dr Stuart Butchart FRS, Chief Scientist, BirdLife International, and senior editor of State of the World’s Birds examined ‘Why flyways matter.
This report highlights a fundamental truth: a flyway is not simply a line on a map, but a broad interconnected network of critical sites and essential habitats supporting migratory birds across continents and seasons. When one link is broken or weakened, the entire chain is at risk.
Recognising this inter-connectedness, BirdLife International – the only global Partnership conserving birds and all life on our planet, with 125 Partners in 120 countries – developed the Global Flyways Programme.
Rather than focusing on individual sites, species or national borders, this approach aims to secure and restore entire flyways, with Partners working together from breeding grounds to stopover sites and non-breeding areas.
World leaders sign the Nairobi Flyways Declaration
At the summit today, leaders, scientists and conservation organisations signed the Nairobi Flyways Declaration, an unprecedented commitment to coordinated, flyway-scale conservation.
The Declaration recognises that migratory birds cross borders and continents; their survival depends on action by many stakeholders across entire flyways, not isolated national efforts.
“We stand at a turning point. Migratory birds do not recognise borders. They connect Asia to Africa, the Arctic to the tropics. The Nairobi Flyways Declaration acknowledges this reality.
“I am proud to see the scientific community, conservation organisations and finance institutions united behind the science. This is the moment we have been waiting for.”
Her Imperial Highness Princess Takamado, and Honorary President, BirdLife
Billions being mobilised for flyway conservation
Senior representatives from the World Bank and regional development banks attended the summit, signalling unprecedented institutional commitment.
Three multilateral development banks are integrating flyway conservation into their lending frameworks, bringing commitments made since 2021 to more than $6 billion.
The Asian Development Bank is mobilising $3 billion over the next decade to protect at least 50 priority wetlands across the East Asian-Australasian Flyway, supporting nearly 200 million people who depend on these ecosystems.
In the Americas, the Development Bank of Latin America and the Caribbean is mobilising $3–5 billion through 2050 to safeguard more than 30 landscapes and seascapes.
The World Bank and BirdLife are mobilising several billion dollars across Africa, Europe and Asia along flyways used by more than two billion migratory birds.
Momentum is also growing for community-led action. In June 2026, the Global Environment Facility approved the Global Flyways Grant Mechanism, providing $8.97 million in direct grants and $107 million in co-financing for conservation and restoration across nine million hectares of wetlands, benefiting an estimated 330,000 people.
“BirdWatch Ireland is proud to sign the Nairobi Global Declaration, which provides an opportunity to protect migratory birds, not just on the African-Eurasian Flyway but across all nine Global Flyways.
“BirdWatch Ireland fully supports the calls to action listed in the Declaration. We need to act now to ensure that migratory birds are fully protected and continue to return to Ireland every year to rear their young.”
Andrew Kelly, Chief Executive Officer, BirdWatch Ireland said: “The State of the World’s Birds report is unambiguous: we are losing migratory birds at an alarming rate.
“But today’s Nairobi Declaration and finance announcements prove something equally clear: when the science is compelling and the case is made, the world acts. Governments are stepping up. Development banks are rising to the challenge. Now we implement at scale.”

STATE OF THE WORLD’S BIRDS: KEY STATISTICS
• 45% of migratory bird species are in decline
• tne in nine (11%) migratory species is threatened with extinction
• Seven migratory species confirmed or suspected to have been lost in the last 150 years
• Slender-billed Curlew was officially declared extinct in 2025; last confirmed record Morocco, February 1995 — the first global bird extinction in mainland Eurasia and Africa in recent centuries
• Seabirds and shorebirds are the most threatened groups; species dependent on marine habitats, forests and coastal wetlands are faring particularly poorly
Drivers of decline are overwhelmingly human-caused: invasive alien species; agricultural expansion and intensification; climate change; and unsustainable hunting and trapping Ecological Restoration Fund followed in June 2026. The route supports more than two billion migratory birds crossing Africa, Europe and Asia.
