Swifts' physical characteristics enhance flight efficiency by increasing lift and decreasing drag.
Swifts possess physical characteristics such as cone-shaped heads and long, tapered wings that aid in swift flight by reducing drag and increasing lift.
These characteristics mainly allow the swift to increase lift and decrease drag, helping them fly quickly and for long distances.
Feathers play a crucial role in providing lift and thrust necessary for birds to fly, and their wing design contributes to reducing drag for efficient flight.
