Melbourne: Scientists have discovered fossils of the world’s largest parrot, standing up to one metre tall and weighing seven kilogrammes (kg) with a massive beak able to crack most food sources. The new bird, described in the journal Biology Letters, has been named Heracles inexpectatus to reflect its Herculean myth-like size and strength — and the unexpected nature of the discovery. “New Zealand is well known for its giant birds,” said Trevor Worthy, Associate Professor at Flinders University in Australia.

However, until now, no-one has ever found an extinct giant parrot — anywhere,” Worthy said. The fossil is about the size of the giant ‘dodo’ pigeon of the Mascarenes and twice the size of the critically endangered flightless New Zealand kakapo, previously the largest known parrot. Like the kakapo, it was a member of an ancient New Zealand group of parrots that appear to be more primitive than parrots that thrive today on Australia and other continents, researchers said.

Birds have repeatedly evolved giant species on islands. As well as the dodo, there has been another giant pigeon found on Fiji, a giant stork on Flores, giant ducks in Hawaii, giant megapodes in New Caledonia and Fiji, giant owls and other raptors in the Caribbean.Heracles lived in a diverse subtropical forest where many species of laurels and palms grew with podocarp trees. “Undoubtedly, these provided a rich harvest of fruit important in the diet of Heracles and the parrots and pigeons it lived with. But on the forest floor Heracles competed with adzebills and the forerunners of moa,” said Professor Suzanne Hand, also from UNSW Sydney. “The St Bathans fauna provides the only insight into the terrestrial birds and other animals that lived in New Zealand since dinosaurs roamed the land more than 66 million years ago,” said Paul Scofield, Senior Curator at Canterbury Museum.
