It was thought that the aerodynamics of flapping flight in birds is fully understood for quite some time, but recent studies … WebBirds fly in a variety of ways, ranging from gliding to soaring to flapping flight to hovering.Of these, the simplest type of flight is gliding. A gliding bird uses its weight (mass) to overcome air resistance to its forward motion. To do this effectively, of course, requires a certain mass &, as a result, only large birds, such as vultures, glide on a regular basis.
