Our pal mental_floss has a really neat article about the Lazarus species, basically animals that were once thought to be extinct, until they were rediscovered.
This one to the left is the devil bird:
This diabolical ave wasn’t thought to be real until 2001. In Sri Lanka, where the Devil Bird legend originated, the bird is known as Ulama. It has a shrill shriek that sounds eerily human-like and is said to predict the death of a loved one. But when the Spot-bellied Eagle-owl was discovered seven years ago, it was quickly realized that it matched the description of the Devil Bird quite closely.
