A type of behaviour practised by some songbirds in which they allow ants to run through their plumage. Often the birds fully open their wings and lie on the ground to encourage them, sometimes even picking them up in their bills and rubbing them over their feathers. It's thought that this behaviour releases the ants formic acid, which may help kill parasites in the plumage or act as insect repellent .
