Like a parachute, a birdâs wings catch air.
usually too small to be seen. Those particles
help a bird fly.
A birdâs wings angle downward in the back.
The birdâs forward movement forces air flowing
under the wing downward.

When a bird flaps
downward, it pushes
more air than if it held
its wings still.
The air moving under the wing creates a
force that pushes the bird upward. Flapping
pushes even more air under the wings.
Birds with long wings can create a lot of lift.
Their wings push a lot of air downward. The
wandering albatross has the longest wingspan.
Its wingspan is up to 11.8 feet (3.6 m) wide. The
bird can travel thousands of miles by soaring.
