At one time, New Zealand’s oversized species of bird had only one natural predator, the Haast’s Eagle. Enter the presence of man, the Maori people, and suddenly the moa were dropping like flies, falling victim to hunting and deforestation. This wingless, flightless bird was wiped clean from the planet by 1440 AD, its oddly shaped, yet still slightly majestic form eradicated entirely with help from the Maori. Moa grew to a heigh of nearly 3.6 meters or 12 feet in height, and could weigh up to 230 kilograms or 510 pounds. If you’re at all disappointed to not have seen this massive bird in the flesh, then you’re in luck, as the moa has been looked at as a potential cloning candidate.
