Birds are running out of places to land: 45% of migratory bird species now in decline

Imagine a bird navigating the ancient, invisible highways of the sky, a creature evolved over millennia to trust the rhythms of the earth. For centuries, these aerial travelers relied on specific stopover sites—wetlands, forests, and grasslands—to refuel and rest before crossing vast oceans or deserts. Today, that trust is being shattered. As we gather in Nairobi for the Global Flyways Summit, the reality is stark: nearly half of the world's migratory bird species are now in decline. They are literally running out of places to land.

This crisis is not a sudden collapse but the culmination of decades of slow, grinding erosion. Wetlands in the Americas have been drained for agriculture, forests in Asia have succumbed to urban expansion, and critical sites in Africa have been paved over for development. When a migratory bird reaches a flyway, it is not looking for a generic patch of land; it is searching for a specific ecological niche where its physiology can be maintained. Without these precise refueling stations, the birds cannot complete their journeys, leading to population crashes that ripple through entire ecosystems.

The State of the World's Birds report, published today, makes these invisible losses visible. It reveals that the decline is not uniform; it is concentrated in the most critical corridors where human activity intersects with natural migration paths. The data tells a story of fragmentation, where once-connected landscapes are now broken islands. For a bird flying thousands of miles, the difference between a suitable stopover and an uninhabitable wasteland is the difference between survival and extinction. The report serves as a stark warning that our stewardship of these shared spaces has failed the most mobile of all wildlife.

Yet, within this grim news lies a powerful call to action, one that brings together a diverse coalition of BirdLife Partners, NGOs, governments, and financial institutions. At the summit, these stakeholders signed the Nairobi Flyways Declaration, a historic commitment to protect and restore migratory habitats across borders. This is significant because migration is a transboundary phenomenon; a wetland in one country is a lifeline for birds in another. The declaration acknowledges that no single nation can solve this alone, requiring unprecedented levels of international cooperation and resource sharing.

Moving from pledge to practice, the Regional Flyway Initiatives spanning Africa, Asia, Europe, and the Americas are now shifting into delivery mode. This transition from rhetoric to action is where the real work begins. It involves mapping critical sites, securing legal protections, and funding restoration projects with the precision required to rebuild these ecological highways. Financial institutions are beginning to align their lending practices with these conservation goals, understanding that protecting migratory corridors is an investment in global biodiversity security.

The path forward requires us to see the world through the eyes of these travelers. Every hectare of restored wetland, every protected forest corridor, and every policy change represents a landing spot for a species on the brink. By honoring the Nairobi Flyways Declaration and executing the regional initiatives with rigor, we can reverse the tide of decline. The birds are waiting for us to build these bridges back to their homes; we must ensure they are strong enough to hold.
