International Framework Ratifies Marine Flyways for Coordinated Seabird Protection

International governmental bodies have formally adopted a conservation strategy centered on the migratory pathways of seabirds, designated as marine flyways. This framework directly addresses the challenge of fragmented protection for avian species whose extensive oceanic movements cross multiple political jurisdictions across the world's major ocean basins.

The inter-governmental structure was ratified during the Convention on Migratory Species (CMS) COP15, which convened in Campo Grande, Brazil, in March 2026, under the theme “Connecting Nature to Sustain Life.” Scientific analysis underpinning this policy identified six principal marine flyways spanning the Atlantic, Pacific, Indian, and Southern Oceans, mapping the connectivity utilized by 151 distinct seabird species. This research, employing a dynamic time warping clustering approach on tracking data spanning from 1989 to 2023, indicated that these routes are often used bidirectionally and align with major wind-driven ocean currents.

The new framework explicitly recognizes the imperative of connectivity for species viability, cataloging over 1,300 Key Biodiversity Areas situated along these critical migratory corridors. Applying a large-scale, connectivity-focused lens to the marine environment, this concept addresses the reality that conservation systems often terminate at political boundaries while migratory species continue their journeys. Nearly half of the migratory seabird species covered by this mapping, approximately 42% of the 151 species, are currently classified as globally threatened, underscoring the necessity for coordinated international action.

Key pressures identified across these oceanic networks include the introduction of invasive species, incidental capture in commercial fisheries known as bycatch, and the escalating effects of global climate change. For example, bycatch in longline fisheries is cited as a major driver of population decline for the Endangered Grey-headed Albatross, which ranges widely across the Southern Ocean Flyway. The framework aligns with broader international conservation goals, serving as a precursor to the COP17 on Biological Diversity scheduled for October 2026.

To translate this agreement into field action, BirdLife International is scheduled to host a Global Flyways Summit in Nairobi, Kenya, on September 11, 2026. This gathering will convene governments, scientists, and conservation organizations to highlight successful interventions and build partnerships for concrete measures. Expected agenda items include establishing new marine protected areas, eradicating invasive species from vital breeding colonies, and expanding safer fishing protocols across the identified routes. Commitments from organizations like NOAA Fisheries, which works through regional fishery management organizations to mitigate bycatch, reinforce the cooperative approach for species traversing entire oceans.
