Hmmm, apart from a bit of pesky extinction, it seems we could have been known as Eagles rather than Kiwis.
The BBC reports: Huge eagles ‘dominated NZ skies’
One of the largest birds of prey ever recorded, an extinct giant eagle, was once New Zealand’s chief predator, DNA evidence from fossil bones indicates. … But it was driven to oblivion about five centuries ago, just 200 years or so after the first humans arrived. … Forest fires destroyed its habitat and humans exterminated its food supply. There is also some evidence to suggest the eagles were hunted.
Before humans arrived, New Zealand had virtually no terrestrial mammals apart from bats, the only inhabitants were about 250 species of bird.
