Question: what family do Kiwi and the common ostrich belong to?
Context: The South African ostrich ("Struthio camelus australis"), also known as the black-necked ostrich, Cape ostrich or southern ostrich is a subspecies of the common ostrich endemic to Southern Africa.  It is widely farmed for its meat, eggs and feathers. Struthiolaria papulosa, common name the "ostrich foot snail" or "ostrich foot shell", is a species of medium-sized sea snail, a marine gastropod mollusc in the family Struthiolariidae. 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. Birds are the group of amniotes with the smallest genomes.  Whereas mammal and reptilian genomes range between 1.0 and 8.2 giga base pairs (Gb), bird genomes have sizes between 0.91 Gb (black-chinned hummingbird, "Archilochus alexandri") and 1.3 Gb (common ostrich, "Struthio camelus").  Just as happens to any other living being, bird genomes’ reflect the action of natural selection upon these animals.  Their genomes are the basis of their morphology and behaviour. The Somali ostrich ("Struthio molybdophanes") also known as the blue-necked ostrich is a large flightless bird native to the Horn of Africa.  It was previously considered a subspecies of the common ostrich, but was identified as a distinct species in 2014. Toktokkies are a variety of species of beetles that belong to the large Tenebrionidae family, also known as Darkling beetle.  Toktokkies do not belong to a particular tribe or genus of Tenebrionids, but rather a selection of flightless species with distinct tapping noises.  The Tenebrionidae family to which these beetles belong is quite large, with almost 3,500 species inhabiting Southern Africa.  Nearly 200 species of Toktokkies inhabit the country of Namibia and 20 have adapted to the extreme temperatures of the Namib Desert.  The most common Toktokkies in the Namib Desert are the Fog Basking beetle ("Onymacris unguicularis") and the button beetle or trench-digging beetle ("Lepidochora discoidalis"). The Masai ostrich ("Struthio camelus massaicus"), also known as the pink-necked ostrich or East African ostrich, is a large subspecies of the common ostrich native to East Africa.  Today it is farmed for eggs, meat and feathers. This is a list of the bird species recorded in Oman.  The avifauna of Oman include a total of 494 species, of which five have been introduced by humans and 146 are rare or accidental.  The common ostrich is extirpated in Oman and is not included in the species count.  Twelve species are globally threatened. The North African ostrich or red-necked ostrich ("Struthio camelus camelus"), also known as the Barbary ostrich, is the nominate subspecies of the common ostrich from West and North Africa.  It is the largest subspecies, making it the largest living bird. Kiwi (pronounced ) or kiwis are flightless birds native to New Zealand, in the genus Apteryx and family Apterygidae.  Approximately the size of a domestic chicken, kiwi are by far the smallest living ratites (which also consist of ostriches, emus, rheas, and cassowaries), and lay the largest egg in relation to their body size of any species of bird in the world.
