The dodo bird was a flightless bird that lived on the island of Mauritius in the Indian Ocean. It was about 3 feet tall and weighed around 23-39 pounds. The dodo had a large, hooked beak and a stout body covered in grayish feathers. It primarily fed on fruits, seeds, and nuts. The dodo became extinct in the late 17th century, mainly due to human activities and the introduction of non-native species. Its extinction is often cited as a significant example of the impact of human actions on wildlife and ecosystems. The dodo remains a symbol of extinction and conservation efforts today.
