More than half of the world’s migratory bird species are declining: Study
What we’re seeing is the predictable consequence of decades of environmental degradation. This review goes beyond documenting the crisis by identifying the major threats, highlighting the critical knowledge gaps, and providing a science-based framework for reversing declines before more species are pushed toward extinction,” said Peter P. Marra, Dean of Georgetown University’s Earth Commons Institute and co-lead author of the study.Most visibleAccording to the SoIB Partnership, migratory birds are among the most visible and widespread components of global biodiversity.

Opening excerpt (first ~120 words) tap to expand
A new study led by researchers from Georgetown University and a collaboration of ornithologists from many global organisations, including the State of India’s Birds (SoIB) partnership, has revealed that more than half of the world’s migratory bird species are declining.The authors of the study published in Nature Reviews Biodiversity estimate that approximately 51% of migratory bird species are declining globally across every major flyway on Earth.Biodiversity crisisWhile nearly 300 migratory species are already considered globally threatened, many once-common and widespread birds are also experiencing substantial population losses, underscoring the scale of the biodiversity crisis.In India, this paper found that long-distance migratory birds like those that visit India from the Arctic…
