Contour feathers

Explanation:

Contour feathers are those typical feathers that line the body of the animal and aid in flight. They help reduce drag caused by wind resistance during flight and have a long rake and vane that form a firm blade on the distal portions and have a feathery texture on the proximal portion. The so-called feathered and receding feathers, known as flight feathers, are types of contour feathers found on the wings and tail, respectively.
