A global assessment found that more than half of the world’s 3,380 migratory bird species are declining due to multiple environmental threats.
Major threats include habitat loss, invasive species, hunting, pesticide use, building collisions, and accidental capture in fishing nets.
Migratory birds depend on connected habitats across different countries for breeding, migration, and survival.
Scientists recommend a full annual-cycle conservation approach to protect birds across their breeding grounds, migration routes, and non-breeding habitats.
Advanced tools like tracking devices, genetic studies, automated monitoring, and citizen science programmes help in bird conservation efforts.
