Where it stands

BirdLife International’s new assessment reports declining populations in 45% of migratory bird species. This is the share of species with falling populations, not a count showing that 45% of all birds have disappeared. The report was launched in Nairobi on 11 September 2026 alongside a declaration supporting coordinated conservation across migration routes. Migrating birds need breeding areas, feeding stops and non-breeding habitats in different places. Protecting one wetland cannot compensate for losing another essential site along the journey. India’s role in the Central Asian Flyway makes this a direct conservation issue, not only an overseas wildlife story.

Background

Migratory birds move between places as seasons change, using suitable habitats for breeding, feeding and rest. A flyway is the wider network of routes and sites supporting those movements. A bird can leave a protected breeding area but encounter drained wetlands, unsafe feeding grounds or hunting elsewhere. Its survival depends on conditions across the journey. Conservation therefore needs cooperation among countries and local communities, alongside protection at individual sites. India lies within the Central Asian Flyway, linking northern breeding regions with non-breeding areas farther south.

How it started
India’s flyway role predates the Nairobi declaration

The Convention on Migratory Species established an initiative for the Central Asian Flyway in 2024. Its purpose is to coordinate protection of migratory birds and their habitats across countries. A later decision asks countries to support setting up the coordination unit in India by the end of 2026. This existing process matters because birds visiting India also depend on habitats beyond Indian territory. The Nairobi declaration does not create India’s flyway role from scratch, and it does not establish that every planned institution is already operating.

New fact
The assessment measures species trends and calls for connected protection

BirdLife’s assessment covers 1,843 migratory bird species. It reports 45% declining, 30% stable, 14% increasing and 11% with unknown trends. Monitoring remains uneven, and a global trend can hide losses in one region. The Nairobi Flyways Declaration supports cooperation across the sites birds need during their journeys. BirdLife points to coordinated action that halted decline in the Balkan breeding population of the Egyptian Vulture. That example supports the value of sustained action, not a claim that the species has recovered everywhere. Signing a declaration does not reverse other declines.

Why it matters for UPSC

GS3GS2

For GS3, explain ecological connectivity and why wetland protection must consider an animal’s full annual cycle. For GS2, connect cross-border conservation with cooperation under the Convention on Migratory Species. Keep a population trend, extinction risk and confirmed extinction distinct. A declaration is a commitment to act, not proof of recovery.

Key terms

FlywayA broad network of migration routes and the habitats birds need along them. It includes breeding grounds, resting and feeding stops, and places used outside the breeding season. It is not a single narrow flight path. Damage at an essential site can affect birds that spend much of the year elsewhere.

Stopover siteA place where migrating birds rest and feed during a journey. Some species depend on particular wetlands or coastal feeding areas to obtain enough energy for the next stage. Protecting their destination alone may not help if an essential stopover becomes unusable.

Population trend and extinction riskA population trend shows whether a species’ numbers are rising, stable or falling. Extinction risk assesses the possibility of losing the species, using additional information about its population and range. A declining species is not necessarily already threatened, and a threatened species is not already extinct.

Ecological connectivityThe links that allow animals to move between habitats and complete their life cycles. For migratory birds, those links include usable feeding and resting sites across national borders. Conservation planning must consider how sites function together, not merely how many isolated protected areas exist.

Central Asian FlywayA migration network connecting northern Eurasian breeding areas with non-breeding areas in West and South Asia. India forms part of this network. Its conservation requires action inside India and cooperation with other countries whose habitats support the same birds at different times of year.

Convention on Migratory Species (CMS)An international treaty that promotes cooperation to conserve wild animals moving across national borders. It provides the framework for the Central Asian Flyway initiative. That intergovernmental process is distinct from BirdLife’s scientific assessment and the Nairobi declaration, although they address related conservation needs.
