Birds have wings to fly. Wings are specialized appendages that provide birds with the necessary lift and propulsion to move through the air. The structure and shape of bird wings, including their feathers, allow for the generation of lift and control during flight. This adaptation enables birds to navigate their environment, search for food, escape predators, and migrate long distances. Unlike other animals, birds do not have teeth, and while they do have bones, it is their wings that are specifically designed for flight.
