The emu is a flightless bird native to Australia. It is the second-largest bird in the world, after its relative the ostrich. Emus are found in a variety of habitats, including grasslands, woodlands, and deserts. They are known for their long legs and necks, which they use to run at speeds of up to 50 kilometers per hour. Emus are also known for their distinctive feathers, which are brown and white. They use these feathers to camouflage themselves in their environment. Emus are social animals and live in groups called mobs. They are omnivores and eat a variety of plants and animals, including fruits, seeds, insects, and small reptiles. Emus are an important part of the Australian ecosystem and play a role in seed dispersal and nutrient cycling.
