Feathers are epidermal growths that form the distinctive outer covering, or plumage, on birds and some non-avian theropoddinosaurs. They are considered the most complex integumentary structures found in vertebrates, and indeed a premier example of a complex evolutionary novelty. They are among the characteristics that distinguish the extant Aves from other living groups. Feathers have also been noticed in those Theropoda which have been termed feathered dinosaurs.
Although feathers cover most parts of the body of birds, they arise only from certain well-defined tracts on the skin. They aid in flight, thermal insulation, and waterproofing. In addition, coloration helps in communication and protection.Plumology (or plumage science) is the name for the science that is associated with the study of feathers.
Structures and characteristics
Feathers are among the most complex integumentaryappendages found in vertebrates and are formed in tiny follicles in the epidermis, or outer skin layer, that produce keratinproteins. The β-keratins in feathers, beaks and claws — and the claws, scales and shells of reptiles — are composed of protein strands hydrogen-bonded into β-pleated sheets, which are then further twisted and crosslinked by disulfide bridges into structures even tougher than the α-keratins of mammalian hair, horns and hoof. The exact signals that induce the growth of feathers on the skin are not known, but it has been found that the transcription factor cDermo-1 induces the growth of feathers on skin and scales on the leg.

Filoplume - a central rachis with a little tuft of barbs. Present on almost every part of every bird. Nobody knows what they do.
I hope this helps you next time you find a feather on the ground to get close, investigate, and make predictions. The more you practice, the better you will get at identifying feather types!
