High Quality Content by WIKIPEDIA articles! The Great Spotted Kiwi, Great Gray Kiwi, or Roroa, Apteryx haastii, is a species of kiwi endemic to the South Island of New Zealand. The Great Spotted Kiwi, as a member of the Ratites, is flightless. It is the largest of the kiwi. The rugged topography and harsh climate of the high altitude, alpine, part of its habitat render it inhospitable to a number of introduced mammalian predators, which include dogs, ferrets, pigs and stoats. Because of this, populations of this species have been less seriously affected by the predations of these mammals compared to other species of Kiwi. Nonetheless, there has been a 43% decline in population in the past 45 years, due to the predations of these invasive species and habitat destruction. This has led it to be classified as vulnerable. There are about 22,000 Great Spotted Kiwis in total, almost all in the more mountainous parts of northwest Nelson, the northwest coast, and the Southern Alps. A minority live on islands.
