what family do Kiwi and the common ostrich belong to?
Common ostrich The ostrich or common ostrich ("Struthio camelus") is either one or two species of large flightless birds native to Africa, the only living member(s) of the genus "Struthio", which is in the ratite family. In 2014, the Somali ostrich ("Struthio molybdophanes") was recognized as a distinct species.
Nine-primaried oscine The nine-primaried oscines are a group of songbird families from the superfamily Passeroidea. It is composed of the Fringillidae (finches and Hawaiian honeycreepers), Emberizidae (buntings, American sparrows etc.), Parulidae (New World warblers), Thraupidae (tanagers), Cardinalidae (cardinals), Icteridae (icterids) and the monotypic Peucedramidae (olive warbler). The name of this group arises from the fact that all species within it have only nine easily visible primary feathers on each wing (in reality most, if not all, also have a 10th primary, but it is greatly reduced and largely concealed).
