Do birds have fur or skin?
All birds have them, but only birds have them. Plenty of animals are covered in fur or scales, but birds and their feathers stand alone. Muscles are attached to the base of each feather, which allows the bird to move them as needed. When in flight, as a bird flaps its wings down, the feathers move together.
Is hair present in birds?
Birds are unique among other animals by having feathers. Feathers are dead structures made of keratin, a type of protein that forms many of the epidermal structures in animals (including feathers, hair, nails, claws, and some scales). Some birds have large, colorful tail feathers like a peacock.
Do all birds have skin?

Why do birds and mammals have the same skin?
Some argued that skin appendages developed independently in all species, so birds and mammals just happened to form the same system. Others stated all species possess a molecular placode — a series of genes that spawn hair, feathers and scales — but reptile skin simply fails to sprout a physical structure.
