Body feathers, also known as contour feathers, typically have a streamlined shape that helps reduce drag during flight. They are often flat and overlapping, providing insulation and protection while also aiding in aerodynamic efficiency. The shape can vary slightly among different bird species, but generally, they are designed to fit closely to the body, enhancing both insulation and waterproofing.

A bird's body covering is primarily made up of feathers, which serve various functions such as insulation, waterproofing, and aiding in flight. Feathers come in different types, including contour feathers that shape the bird's body, down feathers for insulation, and flight feathers found on the wings and tail. The coloration and patterns of feathers can also play a role in camouflage, mating displays, and species identification. Additionally, some birds may have a layer of down under their feathers for extra warmth.
A bird's feathers are specially designed to be lightweight, yet strong and flexible. They help create lift and thrust during flight by providing a large surface area for air to push against. Additionally, feathers help birds to control their speed and direction while flying.
