Organs for the movement of birds might include their wings. Wings are used to move birds in the air and legs are used to move birds on the ground. Cervical air sacs are also organs that help a bird to fly.
Feather covered wings allows many species of birds to fly through the air. Their legs allow them to walk, hop or grasp onto branches to roost.
Some birds are flightless: The penguin is one example. Penguins use their flippers to 'fly' through the water. On land they waddle, or toboggan by laying on their front and pushing themselves along on the ice with their feet.
