the wind guides the bird better and helps it stay on path unless a horrible storm
The external structure is the wing. Its bones are so not heavy that the wind takes the bird up and allows it to fly.
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
Birds don't necessarily need wind to fly. The flight can become easier when there is wind, depending on the circunstances, but that doesn't mean that a bird cannot fly in the absence of wind. It can become more tiring if the bird is adapted to flight with wind, but the movement of the wings still creates an upward and forward force that keeps the bird flying. For specifics about how do birds fly, search for that question.
the same way they help a bird fly

it does
No. It would be better written, "The wings of the bird help it to fly".

the tail has flight feathers and the flight feathers help a bird to fly.
The answer to the riddle "What can soar but cannot fly" is a kite. A kite can be flown high in the sky, soaring with the wind, but it does not have the ability to fly on its own like a bird or an airplane. It relies on a string and the wind to stay aloft.
