 Range of the Great Spotted Kiwi

The Great Spotted Kiwi or Roroa (Apteryx haastii) is a relatively common species of kiwi from the South Island of New Zealand. KIWI (1029 FM, "Radio Lobo" is a commercial Radio station located in McFarland California, broadcasting to the Bakersfield California The South Island is the larger of the two major islands of New Zealand, the other being the more populous North Island. New Zealand is an Island country in the south-western Pacific Ocean comprising two main landmasses (the North Island and the South Island Unlike its smaller cousin, the Little Spotted Kiwi, the Roroa was able to elude predators, which include pigs, dogs, ferrets and stoats. The Little Spotted Kiwi ( Apteryx owenii) is a small species of Kiwi originally from South Island (what is known is they used to live near Despite this, there has been a 43% decline in population, likely due to these invasive species. This has led it to be classified as Vulnerable. A vulnerable species is a Species which is likely to become endangered unless the circumstances threatening its survival and reproduction improve [1] The Great Spotted Kiwi is the largest kiwi both in weight (females about 3. 3 kg. males about 2. 4 kg) and height (45cm or 18in. ) There are about 20,000 great spotted kiwis in total, almost all in the more mountainous parts of northwest Nelson, the northwest coast, and the Southern Alps. The Southern Alps is a Mountain range which runs along the western side of the South Island of New Zealand. [2] A small population was also introduced on Little Barrier Island. Little Barrier Island or Hauturu lies off the northeastern coast of New Zealand 's North Island. [3]

Discovery
Before the Great Spotted Kiwi was discovered, several stories circulated about the existence of a large kiwi called the Maori Roaroa. In 1871, two specimens were brought to the Canterbury Museum, where they were identified as a new species and were named after the museum's curator, Dr. For other museums of this name see Canterbury Museum. The Canterbury Museum is a Museum located in Christchurch New Zealand Haast. [4]
Distribution and habitat
These kiwis live in higher altitude areas. Populations are present at Nelson, the northwest coast, and the Southern Alps,[2] as well as at Lake Rotoiti Mainland Island[2] and Little Barrier Island. History Early settlement Settlement of Nelson began about 1100 years ago by Māori The Southern Alps is a Mountain range which runs along the western side of the South Island of New Zealand. Lake Rotoiti is a substantial mountain Lake within the borders of the Nelson Lakes National Park. Little Barrier Island or Hauturu lies off the northeastern coast of New Zealand 's North Island. [3] The Southern Alps population is isolated. [2]
Conservation
This bird is often preyed upon by invasive pigs, dogs, ferrets and stoats. It has more of an advantage than other kiwi species over these predators because it lives in rugged areas, where the wet upland population thrives. [2] However, there has been a decrease in population of 43%,[1] which is about 2% a year. [2] It is classified by the IUCN Red List as a Vulnerable species. The IUCN Red List of Threatened Species (also known as the IUCN Red List or Red Data List) created in 1963 is the world's most comprehensive inventory of the global A vulnerable species is a Species which is likely to become endangered unless the circumstances threatening its survival and reproduction improve [1] The most threatened population is in the lower areas. [2]
Behavior
Males are fiercely territorial. [2] They dig burrows to sleep in. The Great Spotted Kiwi is nocturnal in behavior. [5]
Diet
The Great Spotted Kiwi has a good sense of smell. In the ground they search for earthworms and grubs. [5] Most of their diet is composed of invertebrates such as beetles, cicada, crickets, flies, weta, spiders, caterpillars, slugs and snails. Weta are around 70 Insect Species endemic to the New Zealand Archipelago. [6] They will also feed on berries and seeds. [5] To find prey, the Great Spotted Kiwi use their scenting skills or feel vibrations caused by the movement of their prey. [6] To do the latter, a kiwi would stick its beak into the ground. [7] They then use their beaks to dig into the ground. [5] As they are nocturnal, they do not emerge until thirty minutes after sunset to begin the hunt. [7]
Predation
Because adult Great Spotted Kiwis are large and powerful, they are able to fend off most predators that attack them, such as stoats, ferrets, possums and cats. The ferret is a domestic Mammal of the type Mustela putorius furo. A possum is any of about 64 small to medium-sized Arboreal Marsupial Species native to Australia, New Guinea, and Sulawesi However, dogs are able to kill even adults. The dog ( Canis lupus familiaris) is a domesticated Subspecies of the gray wolf, a Mammal of the Canidae family of the order Stoats, ferrets, possums, cats and dogs will feed on the eggs and chicks, meaning 95% of chicks die within their first five months of living.
