Question

Birds Fly in the Sky
How the birds fly in the sky?

Answer 1

In a way, birds use a swimming motion to get the lift needed to fly. Plane wings have a similar shape as bird wings, but instead of flapping their wings, we use engines to thrust them into the air and create the lift needed to fly.

Answer 2

No birds flies in the sky.When birds use their muscles to flap their wings, they create another force called thrust. This force helps them move forward. It's also what gets the air moving over their wings to create the lift. Of course, another advantage birds have for flying is being lightweight.
