How does a bird fly If a bird is just gliding or soaring that is not flapping its wings it flies in pretty much the same way that an airplane flies The wings push air down so by Newtons third law the air must push them up Partly the push comes from the angle the wings are held at and partly from the curvature of the wings The air travels faster above the birds wing than it does below and this makes the pressure lower See Answer
