Dromornithidae
Dromornithidae, known as mihirungs and informally as thunder birds or demon ducks, were a clade of large, flightless Australian birds of the Oligocene through Pleistocene Epochs. All are now extinct. They were long classified in Struthioniformes, but are now usually classified as galloanseres. Dromornithids were part of the Australian megafauna. One species, '' Dromornis stirtoni'', was tall. Only a single species, '' Genyornis newtoni'' survived into the Late Pleistocene. They are thought to have been herbivorous. The scientific name Dromornithidae derives from the Greek words , ("swift-running") and , ("bird"). Classification The family was named by Max Fürbringer in 1888, citing W. B. Clarke and Gerard Krefft, Owen's separation from ''"Dromaeus"'' and '' Dinornis'', and a note by von Haast allying ''Dromornis'' with ''Dromaeus''. What the nearest relatives of this group are is a controversial issue. For many years it was thought that dromornithids were related to ...

Dromornis Stirtoni
''Dromornis'' is a genus of large to enormous prehistoric birds. The species were flightless, possessing greatly reduced wing structures but with large legs, similar to the modern ostrich or emu. They were likely to have been predominantly, if not exclusively, herbivorous browsers. The male of the largest species, ''Dromornis stirtoni'', is a contender for the tallest and heaviest bird, and possibly exhibited aggressive territorial behaviour. They belong to the clade dromornithid, extinct flightless birds known as mihirungs. Taxonomy The genus was erected to separate a new species, ''Dromornis australis'', from the previously described ''Dinornis'' (giant moas), another lineage of ancient large and flightless birds found in New Zealand that was earlier described by Richard Owen in 1843. A femur that was forwarded to England, probably a dromornithid and since lost, suggested an Australian genus, but Owen withheld publication for many years. The type specimen, another femur, was ...
