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 beak and a stout body, with grayish-brown feathers. It became extinct in the late 17th century, primarily due to human activities and the introduction of non-native species. The extinction of the Dodo bird is often cited as a significant example of the impact of human actions on wildlife. Its disappearance has led to increased awareness about conservation and the importance of protecting endangered species and their habitats.
