Aepyornithiformes

Machine-translated from the Italian article

The elephant birds are a group of extinct large, flightless birds belonging to the order Aepyornithiformes, endemic to the island of Madagascar. These birds are believed to have become extinct around 1000 AD, probably due to increasing human activity on the island. The elephant birds comprised three species: one in the genus Mullerornis and two in the genus Aepyornis.
