Wings are appendages or structures that allow an organism to fly. They are typically found on birds, insects, and bats.
Feathers: These are the light, flat structures covering a bird's body and wings. They help in flight by creating lift and reducing drag.
Flight muscles: These are specialized muscles in flying animals that provide the power for flapping their wings.
Aerodynamics: This is the study of how air moves around objects. In biology, it helps explain how wing shape affects an animal's ability to fly.
