When a crow isn’t feeling well, it lands near an ant nest, spreads its wings and… stands there, still, letting the ants climb onto its body. But why? The ants release formic acid, a natural substance with antiparasitic properties. This “chemical bath” helps eliminate fungi, bacteria and parasites from the skin and feathers. This behavior is so common that it even has a name: “anting.” And it’s not just among crows — several species of birds do this as a form of self-medication. Nature is a living pharmacy. And animals know exactly where to look for a cure.
