Passeriformes-anting is a special behavior of passerine birds where they pick insects or a certain type of ants and rub them against their feathers. They avoid ants that sting and select ants that give off or spray formic acids or other protecting fluids. It is suggested that this activity helps to reduce parasites like mites or is effective in controlling fungi or bacteria.
