Why does not gravity pull a bird down when it is flying?

    Before we can ask that Q, we must satisfy the Q: "What is gravity?"
    .
    What prevents the bird from drifting out of the Solar System? Why does the Moon remain faithful to Earth and Earth to the Sun? What physical entity comes up against the skin of the bird and restrains it?

    Because our air allows for lift under the bird's wings thanks to the bird's airspeed.

    Because the bird's wings, beating on the air, give an upward thrust which counteracts the downward pull of the earth.

    It does pull the bird down, in much the same way it would pull you down if you were jumping.  However, as a bird flaps its wings, it provides a force resulting in lift.  As long as the lift force is larger than the downwards force acting on the bird due to gravity (simply its weight) then the bird will stay aloft.

      Are there any sane people here? We're talking about gravity, not about birds! The bird was an EXAMPLE. A mathemagician is someone who answers a Q that was not asked. You point at the Moon and he stares at your finger. The Moon? Gravity? Anyone?

    birds body design is flawed (gravity does have an affect on birds) but their bone structure  makes them as light as possible.  Birds are also very strong animals.  Other factors are their diet and internal functions such as no bladder.

      See reply for Physicshelp above. (You wonder what help he can give in Physics if he can't follow a simple conversation.) Please answer why the Moon doesn't drift out of the SS. Forget about the bird.
