What does a moa sound like?

Moa, an extinct flightless bird from New Zealand, is believed to have produced low-frequency vocalizations, similar to those of modern large birds like ostriches or emus. While no recordings exist, some researchers speculate they may have had deep booming calls or guttural sounds used for communication. Their vocalizations likely varied depending on the species and context, contributing to their role in the ecosystem before their extinction.
