Answer 2

because their density is less than the density of air....
 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.
