The large flightless bird native to Australia is the emu. Emus are the second-largest bird in the world by height, standing up to 1.9 meters (6.2 feet) tall. They have long necks, large bodies covered in brown feathers, and long legs that allow them to run at high speeds. Emus are primarily herbivorous, feeding on grass, seeds, fruits, and insects. They play an essential role in the ecosystem by assisting in seed dispersion. Emus are also notable for their unique mating rituals and for being one of the key symbols of Australian wildlife, featuring prominently in Aboriginal culture and stories.
