Unknown Feather
Feathers are epidermal growths that form the distinctive outer covering, or plumage, on birds. They are considered the most complex integumentary structures found in vertebrates[1][2] and a premier example of a complex evolutionary novelty.[3]They are among the characteristics that distinguish the extant birds from other living groups.[4]
