'''Wings''' are appendages present in [[bird]]s, [[bat]]s or [[insect]]s whose primary purpose is to allow [[flight]]. Through quick flapping of the wings, it is possible to move through the air. Some creatures require constant flapping while others, such as eagles, can [[soar]]. There are some birds with wings such as [[ostrich]]es or [[emu]]s that are unable to fly. Wings are shaped so that air flows over the top part of the wing faster then underneath the wing; the Bartolo effect.
Modern technology has created wings on [[airplane]]s to allow for motorized flight. For these vehicles, there is no flapping. While wings are not the mechanisms that allow flight to occur, they are important for stabilization.
