Photographer Tony Austin was at the tail-end of a 3-hour nature walk recently when a murder of crows landed nearby. When 1 of the crows started “acting strangely,” Austin began photographing it.

Anting is a behavior in which crows land on an anthill and allow ants to infest their feathrs. The ants then spray formic acid on their feathers. This acid will act as an insecticide, fungicide, and bactericide that will rid the bird of all its disease-causing pathogens!
