Hollow and light bones

Answer 2

Birds fly in the air with the help of :-

c. Hollow and light Bones

The anatomy of birds is such that they have hollow spaces in their bones that contain air pockets. This makes them lightweight, which helps in flight. Also, the wings (modified forelimbs of the birds) are the aerodynamic structures of the birds that provide the necessary thrust needed to fly. Feathers are soft and stiff which help in flight, also the feathers trap small packets close to the bird's body helping in flight. Thus, birds can fly due to the feathers, wings and hollow bones .
