Tail feathers Most tail feathers, or rectrices rectricesRECT-ri-seestail feathers, feature an interlocking microstructure similar to wing feathers. Arranged in a fan shape, these feathers support precision steering in flight. Typically, birds have six pairs of feathers on the tail, which display increasing levels of asymmetry toward the outer ...
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 [1][2] and an example of a complex evolutionary novelty. [3] They are among the characteristics that distinguish the extant birds from other living ...

The Parts of a Feather and How Feathers Work - Science of Birds
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 a unique adaptation of birds. Feathers are made up of keratin, an insoluble protein that is also found in mammalian hair and reptilian scales.
An interactive tutorial from the Cornell Lab of Ornithology learn & teach about feathers & bird science. Diagrams, animations, videos & fun quizzes.
Bird - Feather Evolution, Flight, Adaptation: Feathers are complex and novel evolutionary structures that evolved before birds and avian flight. The evolution of avian flight required decoupling the coordinated movements of the limbs. Major avian diversification probably took place during the Cretaceous, and almost certainly all living orders were in existence by the end of the Eocene.
