Domain: Eukarya

Eukaryotes have membrane-bound organelles, complex cells, and their genetic material is held in the nucleus.

Kingdom: Animalia

Animals are motile, lack cell walls, have no alternation of generations, are multicellular, and are heterotrophic.

Phylum: Chordata

Chordates have a notochord, hollow dorsal nerve cord, pharyngeal gill slits, an endostyle, and a post-anal tail at some point of development. They also have a well-developed coelom, are bilaterally symmetrical, and are triploblastic.

Class: Aves

Birds have modified structures for flight: epidermal scales modified to feathers; bone structures modified for flight (reduced weight) and larger breast bone for wing attachment.

Order: Struthioniformes

They are flightless birds.

Family: Apterygidae

They have no keel on their sternum and lack a strong anchor for their wing muscles, so they could not fly even if they developed suitable wings.

Genus: Apteryx

Kiwis are nocturnal flightless birds with long necks and stout legs.

Species: Apteryx haasti

They have a grey-brown plumage with lighter bands and are the largest of the kiwi species.
