I am the largest bird in the world, I can grow up to 2.7m high. My Family and I are proudly the birds who lay the largest eggs in the world. Our eggs are so strong that even a human can stand on top of them and they will not break. Our eggs are also famous for holding up to 1.25 liters of water, and can be used to keep water cool in the ground. No wonder that hunter-gatherers use our eggs to store water in for future use.
