For the sake of consistency, animals falsely thought to be extinct have not been included (coelacanth, Chacoan Peccary, ivory-billed woodpecker).
The Devil Bird, or Ulama, is a frightening horned bird of Sri Lankan folklore. This elusive creature is rarely seen, but is often heard in the form of its infamous, blood-curdling screams. Its cries are said to resemble a wailing woman and are perceived by locals as an omen of death. For centuries, the nocturnal cries of the Devil Bird were the only evidence of its existence; Western science wrote if off as mere superstition.
