The documentary illustration of the Giant Moa, a flightless bird that stood up to 3m and weighed up to 230kg, was hunted to extinction by 1445 AD. They were the primary food source of the Māori who had arrived in New Zealand between 1250-1300 AD. Interestingly enough, the moa was also the primary food source of Haast’s eagle, considered to be the largest eagle to have ever existed. Weighing up to 18kg and with wingspans that reached up to 3m, Haast’s eagle was specifically designed to hunt moa. However, with no large prey left and shrinking habitats, they could not survive and eventually died out. It likely disappeared within a few decades after the moa went extinct.

Well worth a watch.
