Why feather absorbs oil?

Feathers absorb oil because of their unique structure. Each feather is made up of a central shaft with many tiny barbules branching off on either side. These barbules are further divided into even smaller hooklets. When oil comes into contact with a feather, the barbules and hooklets act like a net, trapping the oil droplets. In addition, the surface of feathers is coated with a thin layer of waxy oil called preen oil, which helps to repel water and further aids in the absorption of oil.

The ability of feathers to absorb oil is a vital adaptation for birds. Birds rely on their feathers to stay warm, dry, and buoyant. Oil can damage feathers, making them less effective at performing these essential functions. By absorbing oil, birds can keep their feathers in good condition and maintain their health and survival.

The oil-absorbing properties of feathers have also been used by humans for a variety of purposes. For example, feathers have been used to clean up oil spills, make pillows and comforters, and even create art.
