The Dodo and the Red Hen, A Saga of Extinction, Misunderstanding, and Name Transfer: A Review

The chronology of observations of two extinct flightless birds in 17th century Mauritius, the dodo (Raphus cucullatus) and the red hen (Aphanapteryx bonasia), and what names or descriptions were used for them, is re-examined. It was concluded that the balance of probabilities is strongly against birds called dodaarsen without descriptions in the 1680s being dodos rather than red hens. The dodo had disappeared earlier due to predation by pigs, but a hiatus in settlement broke observational continuity, yet folklore preserved the name and transferred it to the red hen. The dodo's extinction thus happened unobserved.
