The Elephant Bird was a large, flightless bird that lived on the island of Madagascar. It is believed to have gone extinct around the 17th century. These birds could reach heights of up to 10 feet and weighed over 1,000 pounds, making them one of the largest birds to have ever existed. Their eggs were also enormous, with some measuring over a foot in length. Elephant Birds were herbivores, primarily feeding on fruits, seeds, and leaves. Fossil evidence suggests they played a significant role in their ecosystem, possibly aiding in seed dispersal. Their extinction is thought to be linked to human activity and habitat destruction.
