Global Seabird Routes Mapped to Transform Ocean Conservation

Brazil has led a global agreement to map marine flyways used by seabirds, creating a new framework to protect ocean biodiversity and guide international conservation efforts.

“Seabirds have been tracing these routes for millennia; they have shown us the map, now it is our turn to follow it with urgency and shared commitment,” said Tammy Davies, seabird conservation expert at BirdLife International.

Scientists have identified six major marine flyways spanning the waters of 54 countries and used by more than 150 migratory seabird species, including Arctic terns that travel nearly 100,000 kilometres each year. Around 42% of these species are threatened, yet the new framework allows countries to coordinate actions such as marine protected areas, safer fishing practices and habitat restoration across entire migration routes. By linking ecosystems, nations and conservation priorities, the initiative provides a scalable, science-based approach to safeguarding ocean health and reversing seabird declines globally.
