Why Crows Cover Themselves in Live Ants: The Science Behind "Anting"
New Delhi : Nature has some of the most surprising and ingenious ways of keeping animals healthy. A fascinating behavior among birds—specifically crows—has caught widespread attention: deliberately allowing live ants to crawl all over their bodies and feathers.
While it might look like an uncomfortable situation or an attack at first glance, scientists reveal that it is actually a highly sophisticated grooming routine known as "Anting."
What is "Anting"?
Anting is a specialized behavior in which a bird either rubs live ants through its plumage (active anting) or sits on an anthill with spread wings, allowing the insects to swarm over its body (passive anting).
The Scientific Benefits Behind the Behavior
Natural Pest Control (Formic Acid): When ants feel threatened, they spray formic acid as a defense mechanism. For birds, this chemical acts as a potent natural pesticide, effectively killing feather mites, lice, bacteria, and other harmful parasites.
Feather Maintenance: The chemical secretions help condition the bird's feathers, keeping them clean, flexible, and free of fungi.
Soothes Skin Irritation: During molting seasons when birds shed old feathers and grow new ones, their skin becomes itchy and inflamed. The soothing properties of the acid reduce irritation.
Preparing Ants to Eat: Some researchers believe that by triggering the ants to squirt out their sour formic acid first, the birds render the ants tastier and safer to swallow afterward.
A Natural Spa Treatment
What appears to be a bird rolling around helpless on an anthill is actually nature's version of a spa treatment and chemical bath. It highlights how wildlife utilizes natural elements to maintain hygiene and survive.
