Bird Skin
Birds have a thin and delicate epidermis, or skin, compared to other vertebrates. Their skin produces specialized structures called feathers, which is one of the unique characteristics of birds. Feathers are made up of keratin, a flexible protein that also forms the hair and fingernails of mammals. Thick epidermal scales, like those found in reptiles, usually cover exposed areas of skin, such as the legs and feet.
