The ability to fly means that birds have been able to occupy
             an incredible range of habitats, including cliff faces, rain-forest
              canopies, and mountainsides. Birds have streamlined, lightweight
               bodies with wings that are covered and insulated by feathers. Their
                toothless beaks vary in shape and size according to their diet and
