A giant cannibalistic parrot that stood more than three feet tall and lived in New Zealand 19 million years ago has been dubbed 'squawkzilla'. Scientists reckon the animal, which is officially known as Heracles inexpectatus, feasted on other parrots to nourish its massive frame. The tree-dwelling creature is believed to have used its enormous beak to feed on the flesh of its own species. It is thought to be the largest parrot ever and rivals the famed dodo in its bulk, and towers above the current flightless inhabitants of New Zealand, the kakapo.
