Sacha Dench, a UN ambassador for migratory species and adventurous paraglider pilot known for soaring alongside swans and vultures, shares captivating stories about these often-misunderstood birds. She discusses the dramatic decline of vultures in India, revealing the shocking impact of a veterinary drug. Sacha highlights international efforts to rehabilitate and conserve these vital scavengers, showcasing their ecological importance and the unique challenges they face, such as poaching and cultural misconceptions, sparking a conversation about the urgent need for their protection.
The drastic decline of Indian vulture populations, primarily caused by the harmful effects of diclofenac, prompted urgent international conservation efforts to restore their numbers.
Despite their vital ecological role in preventing disease spread, vultures continue to face negative public perceptions and new threats from poaching, highlighting the need for education and stronger conservation strategies.

The Indian Vulture Crisis
The Indian Vulture Crisis represents one of the most significant declines of wild species ever recorded, with certain vulture populations plummeting by over 90% in just a few years. The investigation revealed that the use of diclofenac, a common anti-inflammatory drug administered to cattle, was the primary cause of this decline due to its lethal effects on vultures that scavenge on the carcasses. Conservationists raced to find a solution, initially ruling out other potential causes such as agricultural toxins and diseases, which highlighted the urgency of the situation. Ultimately, a concerted effort led to a nationwide ban on diclofenac, showcasing the collaboration of scientists and conservationists to rectify a critical ecological crisis.
Vultures as Ecological Heroes
Vultures play a crucial role in ecosystems by quickly consuming animal carcasses, thereby preventing the spread of disease and promoting a healthy environment. This natural cleanup duty emphasizes their importance to human health and welfare, but many people still view vultures negatively due to their scavenging behavior and appearance. For instance, conservationists pointed out that vultures curb disease outbreaks by controlling carrion, but public perception often lacks appreciation for their ecological contributions. Education and advocacy efforts are essential to shift public sentiment and enhance conservation measures for these vital birds.
Addressing the Poaching Threat
Vultures are facing new threats from poaching, as some poachers kill them to conceal their illegal activities by eliminating the birds that would signal the presence of carcasses. Wildlife rehabilitation groups have reported incidents of mass poisonings aimed specifically at vultures, leading to dramatic declines in their populations. For example, a recent case demonstrated a coordinated effort to save birds from poisonings, which involved immediate medical attention and rehabilitation for those afflicted. Such incidents underline the growing need for stronger laws against wildlife crime and comprehensive conservation strategies that engage local communities.
With their fearsome talons, acid poo and a penchant for rotting carcasses, the vulture has long been shouldered with associations of death, and dishonour. This taboo often puts them bottom of the list for conservation projects. Conservationist Sacha Dench visits three different vulture species, each with an extraordinary story of persecution and survival. In India, vulture populations collapsed by 99.9%, the sharpest decline of any animal ever recorded. Debbie Pain and Chris Bowden describe the urgent international collaborative effort that brought them back from the very brink of extinction. In South Africa, the White Backed Vulture has become collateral damage in the ongoing war between poachers and game-keepers. Finally, in Guinea-Bissau, vultures are the victim of cultural practices which see their bodies as having magical properties.
