How do birds fly?
Quick answer
Birds fly by using the special shape of their wings to create lift. Air moving over the curved top of a wing travels faster, lowering pressure above it, so higher pressure below pushes the bird up. Flapping provides thrust to move forward.
Step by step
- Wings are shaped to create lift as air flows over them.
- Faster air above the wing lowers pressure there.
- Higher pressure below pushes the bird upward.
- Flapping generates the thrust to move forward.
