Anting (bird Activity)

Anting (bird Activity)

In the behavior called anting, birds rub insects on their feathers, usually ants, which secrete liquids containing chemicals such as formic acid, that can act as an insecticide, miticide, fungicide, bactericide, or to make them edible by removing the distasteful acid. It possibly also supplements the bird's own preen oil. Instead of ants, birds can also use millipedes. Over 250 species of bird have been known to ant.
