The Haast's eagle (Hieraaetus moorei, formerly called Harpagornis moorei) is an extinct species of eagle that once lived in the South Island of New Zealand, commonly accepted to be the pouakai of Maori legend.
Thought to have been extinct for 1,400 years, there are still some that remain alive on Primeval Island. In fact, they are one of the island's apex predators. They are also one of the most common birds on the Island, alongside the Archaeopteryx, Ichthyornis, Argentavis, Dodo, Iberomesornis, Giant Moa, and Titanis.
