A Talk on the Wild Side.

In 2012, we funded the establishment of a vulture restaurant in Koshi Tappu Wildlife Reserve in Nepal.
Vulture restaurants don’t serve vulture, they serve carcasses to vultures, and they are an important way to help recover vultures – in Asia, IUCN, the International Union for Conservation of Nature, classifies four species as Critically Endangered.
This is largely due to a drug given to livestock.
In Asian countries, people give diclofenac, a drug similar to aspirin or ibuprofen, to livestock to ease arthritic pain.
But vultures are hyper-sensitive to diclofenac. When they feed on livestock carcasses that had received the drug when they were alive, vultures die. And vulture population numbers have tumbled drastically since the drug came into use.
IUCN says that the white-rumped vulture was at one time called “possibly the most abundant large bird of prey in the world,” adding that its overall population “almost certainly numbered several million individuals.” But since the mid-1990s, IUCN says, “it has suffered a catastrophic decline (over 99%) across the Indian subcontinent,” and IUCN puts the total population now at less than 15,000.
There is good news. Bangladesh, India, Nepal and Pakistan have passed laws to eliminate veterinary use of diclofenac, although it remains easily available in many areas, and diclofenac meant for humans is often given to animals.

More good news: A 2012 study by The Peregrine Fund showed that the ban on the drug was letting long-billed vultures in Pakistan begin to recover.
But, “we have a long way to go to fully recover vulture populations throughout South Asia,” said one of the study’s authors, Munir Virani.
Vulture restaurants help vultures on their way to recovery. By providing diclofenac-free carcasses for vultures to eat at feeding stations, they provide safe food. The restaurants can also boost the local economy by drawing ecotourists.
In addition to the restaurant, we support advocacy and education to reduce the use of diclofenac.
Groups are also involved in captive-breeding and monitoring efforts to help Asian vultures and make sure they recover.
But why do we even care about vultures? Aren’t they kind of nasty birds?
Despite what we have learned from pop culture, vultures are not dirty, dumb villains that bring bad luck. These amazing birds are a vital part of the ecosystem.
By eating carcasses, vultures keep their environment clean. Since the meat they eat is often diseased or rotting, vultures have built-in resistance to many diseases, including ones that can spread to people, such as anthrax.
When vultures disappear, other scavengers move in, often with dangerous results. In India, feral dogs became the main scavenger, which brought a serious rabies problem.
September 5 is International Vulture Awareness Day, and as raptor expert Virani said: “We have a long way to go to fully recover vulture populations throughout South Asia.” Let’s all remember these awesome and important birds and those dedicated to their recovery.
