• Crows rub ants on their feathers in a ritual called anting for self-care.
• Ants release formic acid, which may protect crows from parasites and microbes.
• Over 200 bird species and some primates also use ants for similar self-healing.

Crows have been practising a curious ritual for centuries. They roll in ants, creating a cloud of tiny insects. Scientists have long observed this behaviour, called “anting”. It may help birds protect themselves from parasites and microbes. The ritual turns the forest floor into a natural pharmacy for birds.

How Crows Use Ants for Self-Care?

During anting, crows pick up ants with their beaks. They rub them across their feathers, or let ants crawl freely. The ants release formic acid, a chemical with antimicrobial properties.

This acts as a kind of natural antiseptic on the bird’s body. Some birds even disturb ant colonies to provoke chemical release. This ensures the crows are coated evenly in protective substances.

Scientists are still looking for answers

Researchers are still unsure whether anting is deliberate self-medication. It may also provide sensory stimulation or comfort rather than healing. Studies suggest the chemicals could repel parasites, like ticks and mites. The behaviour hints at a hidden intelligence in animal self-care.

Birds just like this crow use ants to get rid of parasites. 🦠 Taking a bath in ants is also called 'anting'. #Censorship is a parasite 🦠 $CAW is #FreedomOfSpeech

Anting is not unique to crows. Over 200 bird species practise similar rituals, including thrushes and blackbirds. Even some primates have been observed rubbing ants on their skin. This shows self-healing behaviours may be widespread in the animal kingdom.

Do other Animals practice similar behaviour?

Crows are not the only ones to perform anting. Over 200 bird species, including thrushes and blackbirds, use ants similarly. Some primates and insects have been observed using ants on skin. Yet, crows remain special for their regular and systematic use of ants. They show both consistency and sophistication, unlike many other species.

Chemical Warfare in Nature

Formic acid is a powerful natural antimicrobial released by ants. Crows exploit this chemical to protect their feathers and skin. It may also inhibit fungal or bacterial infections in feathers. This demonstrates how animals can harness natural compounds for health. It is a rare glimpse into how intelligence and survival intersect. Nature has equipped even common birds with hidden biological tools.
