Grey Heron

Instead of just relying on oil glands to groom themselves like many other birds, grey herons have special specialized patches of feathers on their chest called powder down. These feathers continuously fray into a fine, talcum-like powder. The heron uses its feet to rub this powder all over its body to absorb slimy fish grease, dirt, and blood, and then combs it away. It works like a natural dry shampoo to keep their feathers clean, waterproof, and smooth.
