Dodo

This flightless bird lived a peaceful and happy life on the island of Mauritius. There were no predators, so it didn’t need to fly. The first sighting of it was back in 1598 by Dutch sailors.

As far as we know, they were about 3ft tall with yellow feet, tail feathers, a grey head, and another layer of brown-gray feathers. While there’s no concrete evidence about this extinct animal’s appearance or how it lived, the last sighting of the bird was in 1662. It was in the 19th century that researchers realized the dodo had gone extinct, and it’s believed that the dodo became endangered due to human hunters.

Since they didn’t fear humans, it was easy to track them. In fact, the more noteworthy cause was the introduction of new creatures to the island, including cats, dogs, and, most harmful, pigs. It caused a shift in the ecosystem and the collapse of the dodo’s habitat. The disappearance of the dodo bird was the first time humans were responsible for a species going extinct.
