Contour Bird Feathers

Contour, or vaned, feathers are the most specialized of all feathers. Contour feathers form the outline of the body of a bird, giving it a streamlined look. Included in this group are all of the feathers of the outer body as well as those of the wings and tail. These feathers vary both in thickness and range from the large and stiff flight feathers to the much softer and more delicate feathers that cover and shape the body.
