What Happened
- At least 25 vultures, believed to be Himalayan Griffon vultures (Gyps himalayensis), were found dead in the buffer zone of Dudhwa Tiger Reserve, Lakhimpur Kheri district, Uttar Pradesh.
- The birds are suspected to have died from secondary poisoning — consuming carcasses of dogs that had been killed using poison, likely meant for population control of free-ranging dogs.
- Samples and internal organs of the dead birds have been sent to the Indian Veterinary Research Institute (IVRI), Bareilly for laboratory analysis to confirm the cause of death.
- Six vultures were rescued; four recovered and flew away after treatment; two remain under care.
- The incident occurred on approximately April 7, 2026; birds reportedly died within three to four hours of consuming the poisoned carcass.

India's Vulture Crisis: Causes, Scale, and Conservation Response
India hosts nine species of vultures, and their populations underwent one of the most catastrophic wildlife declines recorded anywhere in the world. In the early 1980s, the three most common Gyps species had a combined population estimated at over 40 million in South Asia; by the 2010s, populations had declined by up to 99.9 percent, with the white-rumped vulture (Gyps bengalensis) effectively disappearing from large parts of its former range.
- The primary cause of the mass decline: veterinary use of diclofenac, a non-steroidal anti-inflammatory drug (NSAID) given to livestock. Vultures consuming carcasses of treated animals suffered fatal kidney failure.
- Veterinary diclofenac was banned in India in 2006; however, secondary poisoning via other toxicants (as in this case) and residual diclofenac continue to cause vulture deaths.
- Four of five vulture species native to Asia remain classified as Critically Endangered by the IUCN: white-rumped vulture, Indian/long-billed vulture, slender-billed vulture, and red-headed/king vulture.
- Himalayan Griffon (involved in this incident) is classified as Near Threatened by IUCN — less endangered but still affected by poisoning incidents.
- India has established Vulture Safe Zones and Vulture Conservation Breeding Centres (at Pinjore, Haryana; Bhopal; Bhubaneswar; and elsewhere).
Connection to this news: The Dudhwa deaths illustrate that vultures remain acutely vulnerable to secondary poisoning — a threat that persists despite the diclofenac ban — as dogs and other animals are targeted with poisons that then enter the food chain of obligate scavengers.
Secondary Poisoning and Wildlife Law
Secondary poisoning — the death of non-target animals after consuming poisoned prey or carcasses — is a major threat to scavengers like vultures, raptors, and hyenas. In India, the use of pesticides or poisons to kill animals is illegal under the Wildlife (Protection) Act, 1972 (WPA) and the Prevention of Cruelty to Animals Act, 1960.
- Schedule I of the WPA, 1972 lists vultures as a protected species — killing or injuring them, even accidentally through negligence, is a cognizable offence carrying imprisonment up to seven years.
- Most vulture species are protected under Schedule I; the Himalayan Griffon is protected under Schedule IV.
- The WPA prohibits using traps, poison, or any other method to hunt or harm Schedule I species.
- Poisoning of free-ranging dogs through organophosphate compounds or other toxins — common in rural areas — is itself illegal under the Prevention of Cruelty to Animals Act and the Animal Birth Control (Dogs) Rules, 2023 (which mandate surgical sterilisation, not culling or poisoning).
- IVRI (Indian Veterinary Research Institute), established in 1889 in Bareilly (UP), functions under ICAR and is the nodal diagnostic institution for wildlife disease investigations.
Connection to this news: If dog poisoning is confirmed as the cause, it opens questions of violation of multiple statutes simultaneously — the Wildlife Protection Act (indirect harm to vultures), Prevention of Cruelty to Animals Act, and ABC Rules 2023 (illegal dog management method).
Tiger Reserves and Buffer Zones: Legal Framework
Dudhwa Tiger Reserve is one of the oldest Project Tiger reserves, established in 1988 and covering approximately 2,201 sq km in Uttar Pradesh. Tiger reserves have a core zone (Critical Tiger Habitat, CTH) and a buffer zone under the Wildlife (Protection) Amendment Act, 2006.
- Project Tiger was launched in 1973; India now has 55 Tiger Reserves covering approximately 78,000 sq km.
- The buffer zone of a tiger reserve allows for compatible human land use while providing a matrix of habitat connectivity; it is not as strictly protected as the core zone.
- The buffer zone is managed for co-existence — which includes human settlements and livestock, creating the conditions under which dog poisoning may occur.
- The National Tiger Conservation Authority (NTCA) administers Project Tiger under the Ministry of Environment, Forest and Climate Change (MoEFCC).
- Dudhwa is also a UNESCO-designated Biosphere Reserve (Terai Arc Landscape); it supports tigers, rhinos, and a rich assemblage of grassland biodiversity.
Connection to this news: The deaths occurring in the buffer zone highlight the tension between human land use (including livestock management and feral dog control) and wildlife safety — a governance challenge in India's protected area network.
