A vulture using a lab rat to check if the carcass contains diclofenac :)
Diclofenac is an anti-inflammatory drug used to treat cattle (also used as NSAID for humans as Diclofenac sodium). This drug has been responsible for mass deaths of Gyps vultures throughout south Asia. Vultures that feed on cattle carcasses containing Diclofenac (also Ketoprofen) suffer from gout and subsequent kidney failure. From 1993 to 2003, Diclofenace wiped out vulture populations by almost 99 percent, endangering several species that were earlier our most common vultures such as the White-backed and the Long-billed Vultures. Veterinary Diclofenac is now banned, and an alternative to it, Meloxicam has been made available, but Diclofenac is still being used illegally as it is cheaper than its substitute, and the threat to our vultures' existence still persists.
