The Dodo (Raphus cucullatus) is an extinct flightless bird that was endemic to the island of Mauritius, east of Madagascar in the Indian Ocean. Its closest genetic relative was the also extinct Rodrigues Solitaire, the two forming the subfamily Raphinae of the family of pigeons and doves. The closest living relative of the Dodo is the Nicobar Pigeon. A white Dodo was once incorrectly thought to have existed on the nearby island of Réunion.

Extinction[edit]

The main reason why the Dodo is extinct is because it was a real target for food. Not only alive were they killed, but some of their eggs were eaten. Usual Dodo eggs were main food for vultures and coyotes. Which led up to the big extinction. It is to be believed that the last dodo was spotted, or seen, in around the 1660s or the early 1670s. There have also been various other animals that are extinct from Maritius.

What were the main predators?[edit]

The main predators are mankind, men to be exact. Hence the fact that they are extinct, the dodos became extinct because of Dutch sailors hunting them for food, and as mentioned above that the Dodo eggs are usual prey to many birds or other land animals who were on Mauritius, preventing more dodos from hatching. The dodos became prey of which many of the Dutch sailor's animals, such as pigs, monkeys, and rats.

Preserves[edit]

Subfossil remains show the Dodo was about 1 metre (3.3 feet) tall and may have weighed 10–18 kg (22–40 lb) in the wild. The Dodo's appearance in life is evidenced only by drawings, paintings and written accounts from the 17th century. Because these vary considerably, and because only some illustrations are known to have been drawn from live specimens, its exact appearance in life remains unresolved. Similarly, little is known with certainty about its habitat and behaviour.

It has been depicted with brownish-grey plumage, yellow feet, a tuft of tail feathers, a grey, naked head, and a black, yellow, and green beak. It used gizzard stones to help digest its food, which is thought to have included fruits, and its main habitat is believed to have been the woods in the drier coastal areas of Mauritius. One account states its clutch consisted of a single egg. It is presumed that the Dodo became flightless because of the ready availability of abundant food sources and a relative absence of predators on Mauritius.

The first recorded mention of the Dodo was by Dutch sailors in 1598. In the following years, the bird was hunted by sailors, their domesticated animals, and invasive species introduced during that time. The last widely accepted sighting of a Dodo was in 1662. Its extinction was not immediately noticed, and some considered it to be a mythical creature. In the 19th century, research was conducted on a small quantity of remains of four specimens that had been brought to Europe in the early 17th century.

Among these is a dried head, the only soft tissue of the Dodo that remains today. Since then, a large amount of subfossil material has been collected from Mauritius, mostly from the Mare aux Songes swamp.

The extinction of the Dodo within less than a century of its discovery called attention to the previously unrecognised problem of human involvement in the disappearance of entire species. The Dodo achieved widespread recognition from its role in the story of Alice in Wonderland, and it has since become a fixture in popular culture, often as a symbol of extinction and obsolescence. It is frequently used as a mascot on Mauritius.
