The Ascension crake (Mundia elpenor) is an extinct flightless bird that previously lived on Ascension Island in the South Atlantic Ocean. Like many other flightless birds on isolated islands, it was a rail. It was declared extinct by Groombridge in 1994; BirdLife International confirmed this in 2000 and 2004. It most likely lived in the near-desert areas of the island and primarily ate sooty tern (Sterna fuscata) eggs. It is probable that it became extinct after rats were introduced to the island in the 18th century, but it may have survived until the introduction of feral cats in 1815.
