Some believe that these birds are described in many legends of the Māori mythology, under the names pouākai, Hakawai (or Hōkioi in the North Island).[52][53] According to an account given to Sir George Grey—an early governor of New Zealand—Hōkioi were huge black-and-white birds with yellow-green tinged wings and a red crest. In Māori mythology, Pouākai would prey and kill humans along with moa,[54][55][56] which scientists believe could have been possible if the name relates to the eagle, given the massive size and strength of the bird.[52][57] However, it has also been argued that the “hakawai” and “hōkioi” legends refer to the Austral snipe—in particular the extinct South Island species.[58]
For context, Haast’s eagle was about twice the size of today’s Harpy eagle, which itself looks like it came out of a nightmare. See photos at www.demilked.com/giant-bird-harpy-eagle/
