Demon Ducks of Doom

Over nine feet tall, Dromornis stirtoni roamed Central Australia more than 8 million years ago. Mihirungs, the common name for this group of extinct birds, is an Aboriginal word meaning giant emu. Mihirungs were a unique group of Australian flightless birds also known as “thunderbirds” and were derived from early waterfowl (ducks, geese, and swans).
