Introduction
Some species vanish silently, yet their absence reshapes entire ecosystems. India’s vultures are one such case. Once dominating the skies in millions, these scavenging birds collapsed by over 99 percent within a single generation. The decision by the Bombay Natural History Society (BNHS) to reintroduce critically endangered vultures in Assam is therefore more than a conservation project. It is an ecological correction, a public health intervention, and a moral reckoning with past policy failures.
When vultures return to the sky, they do not merely reclaim airspace. They restore balance to systems that quietly keep human civilisation safe.
Why Vultures Are Ecological Cornerstones
Vultures perform one of nature’s most vital yet undervalued services: rapid carcass disposal. By consuming dead animals within hours, they prevent the spread of pathogens such as anthrax, botulism, and brucellosis. Their highly acidic digestive systems neutralise bacteria that would otherwise enter soil and water.
The collapse of vulture populations in the 1990s revealed their invisible role in public health. As carcasses accumulated, feral dog populations exploded, leading to a surge in rabies cases. Studies estimate that the vulture decline contributed to tens of thousands of human deaths from rabies in India, imposing enormous economic and social costs.
Beyond sanitation, vultures accelerate nutrient recycling, maintain soil quality, and prevent contamination of water bodies. They are not predators competing for resources; they are recyclers ensuring ecological efficiency.
India’s Vulture Crisis: From Abundance to Near-Extinction
India hosts nine species of vultures, including the White-rumped, Long-billed, Slender-billed, Himalayan, Red-headed, Egyptian, Bearded, Cinereous, and Eurasian Griffon vultures. Among these, the White-rumped, Long-billed, and Slender-billed vultures suffered catastrophic declines of over 99 percent since the early 1990s.
The primary driver was not habitat loss, but pharmaceutical policy failure. Diclofenac, a non-steroidal anti-inflammatory drug widely used in livestock, proved lethal to vultures feeding on treated carcasses. Even trace amounts caused kidney failure and visceral gout in birds.
Additional pressures compounded the crisis: loss of nesting trees, electrocution from power lines, pesticide poisoning, and declining availability of safe carcasses. The vulture collapse stands as one of the fastest recorded population crashes of any bird group in the world.
BNHS Reintroduction: From Emergency Response to Ecological Restoration
The BNHS initiative to reintroduce the Slender-billed Vulture (Gyps tenuirostris) and White-rumped Vulture (Gyps bengalensis) in Assam reflects a strategic shift from protection to restoration.
This programme builds on decades of groundwork: captive breeding centres, toxicology research, advocacy against veterinary diclofenac, and promotion of vulture-safe alternatives such as Meloxicam and Tolfenamic Acid. Reintroduction is attempted only where food safety, nesting conditions, and local awareness have been stabilised.
Unlike reactive conservation that merely prevents extinction, reintroduction aims to rebuild functional populations capable of sustaining ecological roles. It marks the transition from species survival to ecosystem recovery.
Legal and Institutional Framework
India has strengthened legal protection for vultures under the Wildlife Protection Act, 1972. Several species, including the Bearded, Long-billed, Slender-billed, and Oriental White-backed vultures, are listed under Schedule I, offering the highest level of legal protection.
At the global level, the IUCN Red List categorises multiple Indian vultures as Critically Endangered, reflecting their extremely high risk of extinction. This classification has helped mobilise international funding, research collaboration, and policy attention.
BNHS, founded in 1883, has played a pivotal role in translating scientific evidence into policy action, making it one of the rare institutions where conservation science directly shapes governance.
Why Vulture Conservation Is About More Than Birds
The vulture crisis exposed how environmental neglect rebounds on human society. Their disappearance demonstrated the hidden economic value of ecosystem services that markets ignore but societies depend upon.
Vulture conservation intersects with cultural continuity as well. For the Parsi community, vultures are essential to traditional sky burials at the Towers of Silence. Their decline disrupted not only ecosystems but also centuries-old cultural practices.
Thus, restoring vultures is not wildlife romanticism. It is about safeguarding public health, respecting cultural diversity, and acknowledging ecological interdependence.
Challenges Ahead
Despite progress, vulture recovery remains fragile. Illegal or residual use of diclofenac persists in some regions. Habitat fragmentation, power line mortality, and food contamination continue to threaten released populations. Conservation success now depends on sustained veterinary regulation, community participation, and long-term monitoring rather than one-time interventions.
Reintroduction without vigilance risks symbolic success but ecological failure.
Conclusion
The BNHS-led reintroduction in Assam signals a deeper philosophical shift in India’s environmental governance. It recognises that conservation is not about fencing nature away from humans, but about repairing relationships broken by shortsighted policy.
Vultures remind us that ecosystems do not collapse loudly. They fail quietly, until the cost reaches human doorsteps. By restoring these birds to the sky, India is not merely saving a species. It is restoring an ancient contract between nature and society, where each quietly keeps the other alive.

Civilisations fear predators,
but forget their cleaners.
When vultures vanish,
death lingers longer than it should.
