Decline in Migratory Bird Species

July 25 , 2026 15 hrs 0 min 83 0
  • 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.
