In addition to feathers, owl skin also contains a number of other structures, including:
* Oil glands: These glands secrete an oily substance that helps to waterproof the owl's feathers. This is important for keeping the owl warm and dry in wet weather.
* Scent glands: These glands produce a variety of scents that are used for communication between owls.
* Tactile bristles: These bristles are located around the owl's beak and eyes. They help the owl to sense its surroundings and to locate prey.
* Blood vessels: Owl skin is richly supplied with blood vessels, which help to keep the owl warm.
* Nerves: Owl skin is also richly supplied with nerves, which allow the owl to feel its surroundings and to detect prey.
The skin of an owl is a complex and fascinating organ that plays a vital role in the owl's survival.
