The kiwi bird is a flightless bird that is native to New Zealand. Like many other ratites, the kiwi has adapted to life with no keel on its sternum to anchor wing muscles, and its vestigial wings are so small they are often invisible under its feathers.
The kiwi has a long beak that is about a third of the size of its entire body. The female is approximately 16 inches tall and weighs around 6 pounds, while the male weighs around 5 pounds. The bird has thick brown hair-like feathers and has other features that are quite unlike any other bird on the planet.
