Flightless Birds like the Emu and Ostrich tend to have big heavy legs and small wings. Birds that can fly are more streamlined and have bigger wings. These wings have cross-sections shaped like those of aeroplanes enabling them to glide. Their feathers are flat and light in weight. Some of the bones in their skeletons are hollow as well.
