The main reason due to which the birds are able to fly is atmosphere
The birds cannot fly if there is no air (atmosphere)
The birds body is covered with feathers and air cavities are present on the bones of the bird which decreases the weight of the bird and provides more buoyancy
Although the gravitational force acts on bird the bird counteracts this force by flapping its wings by which it pushes the air down and by virtue of air resistance it goes up and thus the birds body is well mechanized to counteract the force of gravity and fly in air
Hope this helped you
