An Emu is a large, flightless bird native to Australia. It is the second-largest living bird in the world, after the ostrich, and is the tallest bird in Australia. Emus are omnivorous, mainly eating seeds, fruits, flowers, and insects, but they will also scavenge for carrion. They live in small groups and have a complex social structure, with a dominant bird leading the group and other birds taking on subordinate roles. Emus are strong, fast runners and can reach speeds of up to 50 kilometers per hour. They are also strong swimmers and can even dive underwater. They are known to be curious and intelligent birds, with a good memory and the ability to recognize individuals. As a result, they are becoming increasingly popular in zoological gardens and parks.
