The plane does not become lighter!
What difference does it make that they are flying or not? None what so ever.
Weight is force as a result of the pull of gravity on a mass.
The mass of the 747 is constant at all times even when the birds are flying so therefore their weight will always be the same.
Do any of you have a bird? If so put its cage on a scale and find its mass.....wait till the bugger gets flying (Alternatively prod it) and the mass will not change.
