Birds use mainly three types of flight, distinguished by wing motion. When in gliding flight, the upward aerodynamic force is equal to the weight. In gliding flight, no propulsion is used; the energy to counteract the energy loss due to aerodynamic drag is either taken from the potential energy of the bird, resulting in a descending flight, or is replaced by rising air currents ("thermals"), referred to as soaring flight. For specialist soaring birds (obligate soare… WebMost passerines, doves, woodpeckers, and game birds have wings that taper down more or less to a point at their outer tip.
