I recently found out that some species of birds are known to have a drug habit. Before you nod off into some daydream about birds railing lines in a bar toilet, let me explain.
A while back, I stumbled across a 65-year-old scientific paper produced by American entomologist and ornithologist Horace Groskin. There was one particular sentence in the essay that really caught my attention: “Birds use the ants to anoint themselves with the formic acid excretions of the ant to give tone to the muscles and also for the general agreeable effect.”
An agreeable effect, eh? Apparently, this behavior is called “anting” and involves grabbing a bunch of ants and rubbing them under your wings. As a means of defense, ants omit formic acid—an organic insecticide—which then gets absorbed by the bird’s body. People have reported seeing birds dancing around with their wings stretched out and their beak wide open, right after having covered themselves with this gross ant spray. A sort of ornithological gurning, if you will. This has led many smart professor types to believe that the act of anting is a vice and that birds do it to get, well, mad-out-of-it.
I decided to ask an expert from the Romanian Ornithological Society about the phenomenon. Ornithologist Stefan Emanuel Baltag told me that anting was quite common amongst several species of birds—namely, the hoopoe, the common starling, the mockingbird, the kestrel, the raven, the crow, and the chaffinch.[…]
