How Does a Bird Fly?

• As the birds wing flaps, air flows faster over
  the upward-curved top than it does across the
  bottom. Fast-moving air has less pressure than
  slow-moving air, so there is more pressure
  pushing up on the wing than there is pushing
  down, creating what scientists call lift. Lift is
  what gets a bird (or an airplane) into the air
  and helps keep it there.
