The Ilbandornis was an ostrich-sized animal, with slender legs than other Dromornithids. The large bill of other species like Bullockornis and Dromornis indicates a carnivorous creature, while the gizzard and amino acid analysis of the eggs of Genyornis indicates Ilbandornis was herbivorous. As yet, the diet is in debate. Both species were found at the same locality in the Northern Territory at Alcoota Station, and dated to the Late Miocene.
