In my previous posts, some commenters mentioned the precipitous decline of vulture populations across the Himalayan region. The numbers are indeed sobering — in 2006, 99% of the Old World vultures in India, Pakistan, and Nepal were wiped out after consuming livestock carcasses that contained the drug diclofenac. The drug is prevalently used as a non-steroidal, anti-inflammatory way to fend off various diseases in cattle. Unbeknownst to cattle farmers, diclofenac remains an active substance in dead livestock, and any vulture that fed on a drugged-up carcass suffered acute kidney failure and a very swift death.
The Old World vultures remain a threatened species, even though diclofenac has been banned in India since its catastrophic consequences in 2006. But enforcement across India’s billion-fold population is difficult, and diclofenac remains a cheap and widely-used ward against disease among cattle farmers. Diclofenac remains a legal drug by livestock farmers in Africa and Europe, but is not the only peril faced by the Old World vultures; in some parts of Africa, witch doctors believe that vultures’ brains and eyes possess mystical abilities, and are heavily hunted as a result. In Mumbai, where kettles of vultures once populated the skies, a Zoroastrian sect known as the Parsi has taken to constructing vulture aviaries to preserve their sky burial customs.
With governments and members of the general public being further acquainted to the ecological importance of vultures, various conservation programs are taking hold across the world. In Africa, there are outreach programs that educate local communities on environmental dangers of pesticides. In wildlife sanctuaries across North and South America, turkey vultures are used as trackers for regional environmental change, and members of the public are able to track their movements through online GPS programs.
With their bloody reputation, vultures haven’t always been treated with the same ardor as some of their fellow carnivores. Tigers, lions, and eagles have been heavily romanticized in literature and across cultures, while cuddly polar bears won’t hesitate to kill a human if they need to eat. The very mention of vultures, on the other hand, usually prompts a nauseous reaction, and even its name is colloquially used as an insult toward the scrounging bums of society. But thanks to the growing spread of information and education, vultures are not only being recognized for their role in nature, but also their possible extinction. Perhaps the Tibetan Buddhists were on to something with their spiritual reverence of these corpse-devouring, bacteria-killing, bald-headed birds.
