Anting is a behavior in birds, including owls, where they rub ants or other small insects into their feathers. It is thought to help keep the feathers clean and free of parasites. Owls will typically find an ant hill and then either stand on it or roll around in it. As they move around, the ants will crawl onto their feathers and begin to bite and sting. The owl's skin will secrete an oil that the ants find attractive, which encourages them to stay. The ants will then use their mandibles to remove any dirt, debris, or parasites from the owl's feathers.
Water
Owls can also use water to help keep their feathers clean. They may fly through a light rain or even take a bath in a shallow pond or stream. When an owl bathes, it will typically dip its head and wings in the water, and then shake its body to remove any excess water. Bathing helps to keep the owl's feathers dry and fluffy, which is important for insulation and flight.
Preening
In addition to anting and bathing, owls also spend time preening their feathers. Preening involves using their beak and claws to remove any dirt or debris from their feathers. Owls will often preen for several hours a day, as it is important to keep their feathers in good condition.
By engaging in these behaviors, owls are able to keep themselves clean and free of parasites. This is important for their overall health and well-being, as well as their ability to survive in the wild.
