Above the wing fast moving air creates low pressure they are curved on the top.

Under the wing slow moving air creates high pressure. The high pressure causes lift. As you can see the bottom of the wing is flat.

Some birds have different wing shapes to make them fly different for example an eagle has long, broad wings for soaring and hovering.

Birds flap there wings to capture the air under there wings to create lift to fly high.

Now you know the difference between bird wings and airplane wings.
