The integument of a Bird consists of Skin and Feathers, the former being composed of a superficial epidermis and an underlying derma or cutis, which is rich in sensory organs but poor in blood-vessels. The epidermis itself has a horny outer layer and a softer (Malpighian) substratum. Feathers, hairs, bristles, scales, claws and bill-sheaths are epidermal structures.
