This list of mythical creatures that begin with this letter and I am constantly gathering information from each continent, and is continually being updated.
Hakuturi (Maori)
In Maori mythology, the hakuturi are guardians of the forest. They are responsible for guarding the forest, and to avenge any desecration of its sacredness. When Rata cut down a tree without first making the proper incantations and rituals, the hakuturi rebuked him by re-erecting the tree. When he showed remorse, they felled the tree again and made it into a canoe for him in a single night.
The hakuturi seem to have been regarded as birds or birdlike: one source calls them the children of T?ne, god of the forest and ancestor of birds. A Ngati Kahungunu version refers to 'the host of Haku-tiri, of Roro-tini, and of Pona-ua'. This last word would seem to imply some relationship to the Ponaturi.
