Question

Mention the features that help a bird to fly is the air????​

Answer 1

Answer:

lightweight, smooth feathers – this reduces the forces of weight and drag. a beak, instead of heavy, bony jaws and teeth – this reduces the force of weight. an enlarged breastbone called a sternum for flight muscle attachment – this helps with the force of thrust.

Answer 2

Answer:

So the shape of the wing and the ability to move it through the air are the two things needed for bird and plane flight. Birds use their strong breast muscles to flap their wings and give them the thrust to move through the air and fly. In a way, birds use a swimming motion to get the lift needed to fly.
