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 [1] [2] and an example of a complex evolutionary novelty. [3]
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.
Feathers are critically important for flight in birds. The flight feathers form long, broad surfaces that have the physical properties needed to generate lift and thrust. They’re lightweight and stiff, but also flexible in just the right way.
Aug 21, 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.
