Adaptations of birds for flight

• has feather that aid flight
• hollow bone to reduce weight
• bones are fused to reduce flexibility
• lightweight, smooth feathers – this reduces the forces of weight and drag
• a beak, instead of heavy, bony jaws and teeth – this reduces the force of weight
• an enlarged breastbone called a sternum for flight muscle attachment – this helps with the force of thrust
• a streamlined body – this helps reduce the force of drag
• wings – these enable the force of lift.
