 Some traditions may list some of these children alongside Rehua, Urutengangana, Aituā, Tiki, Whiro, or Ruaumoko, among others.Often, a war or skirmish between the siblings ends with them becoming the ancestors of certain concepts, habitats, mannerisms, animals, tools, or plants that they each represent.For instance Tāne became Tāne Mahuta, the father of birds and the forest, and Tū became Tūmatauenga, the father of humanity and its activities, such as war.
