The kiwi is a small, flightless bird. The diet of the kiwi consists of juicy plants, berries, seeds, fruit, and insects. They weigh about five pounds and is about the size of an adult chicken. Kiwis lay an egg half of its size, and the male incubates it for two months. The egg is about five inches long. After it hatches it is ready to follow its parents back to the swampy mangroves. The kiwi has ratite feathers like all of the flightless birds. There are only three types of kiwis: the North Island Kiwi, Stewart Island Kiwi, and the Gray Kiwi. At the tip of its six-inch nose are its nostrils which it uses to find its way and its food. It is the only bird with its nostrils at the end of its nose.
