Wing flapping is a movement used by birds and some insects to generate lift and propel themselves through the air. This action involves the rapid up-and-down motion of the wings, which creates differences in air pressure above and below the wings. The shape and size of the wings, along with the speed of flapping, influence how effectively an animal can fly. In addition to birds, bats and insects like butterflies and dragonflies also utilize wing flapping for flight. Each species has adapted its wing structure and flapping technique to suit its environment and lifestyle, allowing for various flying styles, from hovering to rapid acceleration.
