Birds have the lightest body which helps them to fly.There skeleton does not contain bone marrow inside their bone that is they posses hollow bones which help them a lot to take a flight.

this is how birds fly. - how dont know the exact way but everyoune has its skill and tecniques.they use it,we analyse it.
When a bird flaps its wings, air is pushed downward. This produces an opposite force that “lifts” the bird into the air. Since a bird’s wing is in the shape of an airfoil, it produces some lift even when the bird is just gliding. this is all wat i know

birds are the only one to fly because of their light body.they first have to take lessons of flying from their mother and after that they don't depend much on her for safety,food or other reasons.
