Step 1 : Introduction to the question "What is the national symbol of New Zealand?"
...The flightless bird, the New Zealand Kiwi, is the national emblem. It is a nocturnal bird about the size of a large chicken. The female is the larger of the genders and produces the largest egg of all of the bird species. The egg accounts for almost 20 percent of the kiwi's body weight. The female lays only one egg, which she and the male incubate. Originally thought to have evolved from the extinct New Zealand Moa, it was later discovered the kiwi is closely related to the Emu and the cassowaries in neighboring Australia.
