KIWI
Kiwi can refer to people of New Zealand, a bird, a fruit, or a shoe polish brand. Kiwis are the national symbol of New Zealand. Much pride is taken by displaying the kiwi on things such as the national currency, sports uniforms, road signs and mascots.




Apteryx australis, commonly known as brown kiwis, is located in the Australian biogeographic region. They are endemic to New Zealand; they live in subtropical and temperate forests and grasslands. Brown kiwis are members of the flightless ratite group. They range in size from 45 to 54 cm long, and weigh from 2.8 to 3.5 kg. They are brownish grey in color with long, soft feathers that look and feel very fur-like. Their skin is tough and they have whiskers at the base of their bill used for touch. This is especially important for these birds because they have small eyes and poor vision. These birds do not have a tail and their 5 cm long wings prevent them from flying. Brown kiwis have powerful legs and can run quickly. The nostrils are at the end of their long bills and they have a keen sense of smell.
Brown kiwis are described as "honorary mammals" because they have some characteristics that are similary to many mammals. They are nocturnal and communicate through a cry, which sounds like a prolonged whistle slightly ascending and descending. Males make a mournful shriek, "kee-wee," and females have a low hoarse cry.
Brown kiwis are carnivorous, they feed mainly on soil and aquatic invertebrates such as worms, insects, crayfish, amphibians, and eels. They also eat fruit. At night, these birds use their long bills to dig deep into the ground to find creatures living on the ground. After they have caught something, they use their bills to beat the creature on the ground, or on stones to kill it before eating.
