The Dodo bird was a flightless, grey bird with an orange beak and black tip that lived on the island of Mauritius in the Indian Ocean. It had small wings, a white under stomach, and small tail. It used gizzard stones to help digest the tambalacoque fruit it ate, which helped germinate the fruit seeds and spread the plants as an herbivore. It became extinct in the late 1700s with no natural predators but was not aggressive or stupid, laying eggs and shaking its tail rather than flying away.
