Explanation:

Flying birds have 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.

Both aves and mammals are warm-blooded, which means they can maintain a constant body temperature and do not need to rely on an external heat source to stay warm.
