What makes birds fly?

Answer 1

The muscles in the birds body is the only thing that can let a bird fly. But oviously enough, if the wind is strong and blowing to the riht side, the wind l help

Answer 2

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. Birds also rely on the shape of their wings to fly. To start with, their wings are streamlined so the air particles can travel round them smoothly. The bird has equal forces pushing against either side of its wing. To take off, the bird needs to have lift, which means the force pushing the bird up must be stronger than the force pulling the bird down. This can be achieved by making the particles of air flow along the top faster than along the bottom of the wing. Since an equal number of particles must pass along the top and the bottom within the same amount of time, to make them move faster the distance the particles travel on top must be increased. This is why birds have concave wings. The dynamics of bird flight like all physical actions are governed by the laws of physics. In its simplest expression, flying is a balance between two sets of forces. lift and weight, and thrust and drag. Weight is the result of gravity and is reduced as much as possible in birds. Lift is generated by the flow of air over the wings.

Answer 3

Birds are able to fly due to a combination of factors, including their lightweight and aerodynamic body structure, their powerful muscles, and their unique respiratory system that allows for efficient oxygen exchange during flight. Additionally, the shape and arrangement of their feathers help create lift and reduce drag, enabling them to stay aloft.

Answer 4

well i a'int the maker of wiki answers but- birds fly by having feathers, and light and hollow bones and of course, don't eat junk food!
