The red-headed vulture carries inside it something that seems straight out of a chemical weapons laboratory.
Its stomach has a pH close to zero: more corrosive than car battery acid and a hundred times more concentrated than your own gastric juices. Thanks to this, it can eat carcasses in an advanced state of decomposition, teeming with bacteria that would kill almost any other animal within hours.
Within minutes, that extreme acidity destroys lethal pathogens such as anthrax, rabies, botulism, and cholera. This is no exaggeration: every time one of these vultures finishes eating, it is preventing those diseases from spreading to livestock, other species, or even you.
Far from the image of an ill omen they have historically carried, they are one of the most efficient disease-control systems in nature, and they work for free, every day, without anyone thanking them.
