The Indian sect known as Parsees, have a ritual in death, in that they used to routinely expose their dead on a open space so that the vultures would feed and devour the corpse in a matter of hours, leaving nothing at all! Problem is, due to the routine dosing of cattle with a powerful drug named Diclenofac, which is anti-inflammatory and also a veterinary pain-killer, the vultures have been dying off in their thousands, and so sending the Parsee community in urgent search for an alternative drug.
To gain some idea of the effect of these huge flesh-eating birds gathering for the feast, below is a good photograph of such a gathering! N.B. The vultures are all to the rear!
