As nouns the difference between feather and quill is that feather is a branching, hair-like structure that grows on the bodies of birds, used for flight, swimming, protection and display while quill is the lower shaft of a feather, specifically the region lacking barbs. Strong, lightweight contour feathers give birds their coloring and shape.
But how did they evolve? Fun Fact: It is now commonly believed that dinosaurs from the Theropod group of dinosaurs had feathers. All feathers consist of two main parts, the hard central shaft called the rachis and the softer side branches known as barbs. The best quills were made using goose, swan, and turkey feathers. Strong, lightweight contour feathers give birds their coloring and shape. Melanins are common pigments that can make feathers black. You will see them on insectivorous birds, such as flycatchers, which feed on the wing, and they are best developed in goatsuckers, such as Common Nighthawk, which appears to use them to funnel insects into the mouth while flying. National Library of Medicine Pennaceouspennaceouspen-AY-shusshaving an interlocking feather structure that creates a smooth surface, or vane feathers are stiff and mostly flat, a big difference that comes from a small alteration in structure; microscopic hooks on the barbules that interlock to form a wind and waterproof barrier that allows birds to fly and stay dry.

Contour feathers differ from other body feathers (such as down and semiplumes) in that they consist of two vanes along a shaft that have interlocking barbs that give strenght and structure to the feather shape. These birds have developed feather-covered feet which help to increase the surface area, and thus, prevent the birds from sinking into the snow while walking.
