When a crow feels unwell, it perches near an ant nest, spread its wings, stays still and let the ants attack it. They do it for a powerful reason. Ants spray its body with formic acid- a substance that acts as a natural antiparasitic. This acid helps the crow eliminate fungi, bacteria and parasites allowing it to recover from the ailment. This behavior is called “anting” and has been observed in various bird series. It’s an incredible animal self- medication.
