Feather variations. Feathers are epidermal growths that form a distinctive outer covering, or plumage, on both avian (bird) and some non-avian dinosaurs and other archosaurs. They are the most complex integumentary structures found in vertebrates and an example of a complex evolutionary novelty.
From the fluffy down on a swan chick to the brilliant spiral on a King Bird-of-Paradise tail, feathers are remarkable not just in the way they look to the naked eye, but also for their intricate microstructure. Understanding feather anatomy at the microscopic level provides insight into how feathers function.

May 22, 2024 · feather, the component structure of the outer covering and flight surfaces of all modern birds. Unique to birds, feathers apparently evolved from the scales of birds’ reptilian ancestors. The many different types of feathers are variously specialized for insulation, flight, formation of body contours, display, and sensory reception.
Feathers are the most characteristic and specialized component of the avian integumentary system, vital for flight, thermoregulation, visual communication, and protection from the elements. There are several types of feathers, and their size, shape, colors, and functions vary tremendously across different species.
