Genyornis

Genyornis is a large, flightless bird that lived in Australia. Over two metres in height, they were likely either omnivorous or herbivorous. They became extinct 30±5 thousand years ago. Many other species became extinct in Australia around that time, coinciding with the arrival of humans.

In the episode, Monsters of the Outback, a few were lived in their days and peace.
