Vultures are in trouble. In India their numbers have crashed by some 75% and the cause of this appears to be drugs used to treat cattle but which prove lethal to the vultures which feed on their carcasses.
One of these, a drug called diclofenac, has been licensed to be manufactured and used in Spain. It is estimated that populations of vultures could crash if even one percent of the carcasses on which the vultures feed are contaminated with the drug.
