The Genus Raphus, commonly known as the Dodo, is a flightless bird that went extinct in the 17th century. Although there are no synonyms for the genus itself, there are many alternative names that have been given to the Dodo throughout history. Some of the most commonly used synonyms for the Dodo include Raphus cucullatus, Didus ineptus, and Dodo ineptus. Other nicknames include the Red Rail, the Blue Dodo, and the Blue Pigeon. These names were given to the Dodo by explorers and naturalists who encountered the bird on the island of Mauritius, where it was endemic. Today, the Dodo remains one of the most popular symbols of extinction and the need for conservation efforts.
