But if a bird's wings produce the lift, where do the tails come in? Flight Adaptations. A smaller wing loading number means the bird/plane can fly more slowly while still maintaining lift and is more manoeuvrable. 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, light bones a birds bones are basically hollow with air sacs and thin, tiny cross pieces to make bones stronger this reduces the force of weight, a rigid skeleton to provide firm attachments for powerful flight muscles this helps with the force of thrust, a streamlined body this helps reduce the force of drag.
