The great spotted kiwi, as a member of the ratites, is flightless. Population number. Distribution: The Great Spotted Kiwi is widespread and commonly found in woodlands, and subalpine regions in the North-Western part of the South Island, New Zealand. [17] If the kiwis live in an area lacking predators, they will come out in the day. [27] The gestation period is about a month. Kiwis are flightless birds, and hence lack hollow bones, lack a keel to which wing muscles anchor, and have tiny wings. This kiwi has an occurrence range of 8,500 km2 (3,300 sq mi), and in 2000 an estimated 22,000 adult birds remained. [1], The great spotted kiwi is nocturnal in behaviour. The Kiwis egg is the largest of all birds, in comparison to body size and contains the largest proportion of yolk. Great spotted kiwi breed between June and March. Because of this, populations of this species have been less seriously affected by the predations of these invasive species compared to other kiwi. Foreign names . After ten days, chicks venture out of the burrow to hunt. With a long pale bill, short dark legs and toes, often with dark or dark streaked claws. Homes A kiwi's The egg is the largest of all birds in proportion to the size of the bird. It is currently classified by the IUCN as a vulnerable species. Because the birds are still numerous, research effort has instead been concentrated on species that are in serious trouble – such as rowi and Haast tokoeka. Like other species of kiwi, they have a good sense of smell, which is unusual in birds. Three short sentences in succession. Another possible reason is that the places great spotted kiwi live are very inhospitable to their predators. Additionally, kiwi are more closely related to emus and cassowaries than to moa; the latter are actually closest to the weakly flying tinamous of South America. The pair mates about two to three times during peak activity. [17] To find prey, the great spotted kiwi use their scenting skills or feel vibrations caused by the movement of their prey. [6] The kiwi genus, Apteryx, is endemic to New Zealand; 44% of the bird species native to New Zealand are endemic. It is the largest of the kiwi.

However, long-term intensive monitoring shows that populations of great spotted kiwi have remained remarkably stable over 20 years. Great Spotted Kiwi are fiercely territorial and will aggressively defend their territory. The other four are the tokoeka (Apteryx australis), Okarito brown kiwi (Apteryx rowi), little spotted kiwi (Apteryx owenii),[4] and North Island brown kiwi (Apteryx mantelli). The harsh conditions make it tough going for the dogs, cats, ferrets and stoats that would otherwise prey on them. The Great Spotted is found only in the south island mostly in North West Nelson, Central Westland and Eastern Canterbury. It is thought great spotted kiwi have been in part protected by the high altitudes they live in. Northwest Nelson birds are released into the Rotoiti mainland island, to build up the genetic diversity of that population. [10], The great spotted kiwi was first described as Apteryx haastii by Thomas Potts, in 1872, based on a specimen from Westland, New Zealand. Vocalisations of the great spotted kiwi include growls, hisses, and bill snapping. Adult birds are also often attacked by dogs and ferrets. However, dogs are able to kill even adults. The natural kiwi habitat stretches across New Zealand. Great spotted kiwis reside in complex, maze-like b… The largest is the northern brown kiwi, which grows up to 20 to 25 inches (50 to 65 centimeters) and weighs 3.2 to 11 lbs. Two of the eight kiwi taxa can occur in plantation forestry; North Island brown kiwi and great spotted kiwi. [21] At most, four to five kiwis live in a square kilometre. The great spotted kiwi, great grey kiwi[2] or roroa (Apteryx haastii) is a species of kiwi endemic to the South Island of New Zealand. [18] Bird's Nest Fungus sometimes grows in these burrows. When beech trees flower (mast), the number of predators, including stoats, rapidly increases and many kiwi chicks may be killed. [14][15] The great spotted kiwi, along with the other kiwi species, is the only bird with nostrils at the end of its bill. This has led it to be classified as vulnerable. In the wild, sexual maturity for both sexes is between ages three and five. Male very loud shrill warbling whistle; female slower and lower-pitched ascending warble; calls more powerful and slower than Little Spotted Kiwi. [31] Humans have also endangered the species by destroying their habitat by logging forests and building mines. Great Spotted Kiwi (Apteryx haastii) is a species of bird in the Apterygidae family. Unlike most birds, female great spotted kiwis have two ovaries. U Up to fifty burrows can exist in one bird's territory." The Great Spotted Kiwi is one of five species of kiwi. [24] They will often move around, staying in a different burrow every day. Appearance: The Great Spotted Kiwi can be identified as a large pale Kiwi. The table below shows the estimated great spotted kiwi population in 2008 and 2015, and what it could be in 15 years time. Males only leave the nest for a few hours to hunt, and during this time, the female takes over. The five different species of these birds inhabit different regions in New Zealand. Significant populations occur in several plantation forests in Northland, Coromandel, Tongariro, Nelson … The egg is usually about 20-25% of her body mass, so when the egg is produced, there is little room left in her body for much else. The great spotted kiwi, great grey kiwi or roroa (Apteryx haastii) is a species of kiwi endemic to the South Island of New Zealand. [18] The egg-laying season is between August and January. [15] The main threat is from invasive predators including mustelids, brush-tailed possum Trichosurus vulpecula, feral cats, dogs and pigs[1][15] The most threatened populations are in the southern areas of the species' range. Greater spotted kiwis once lived in numerous areas throughout the South Island, but because of predation by invasive species, the remaining kiwi are now restricted to three localities. Haast. By: Ryan Underwood Great Spotted Kiwi Great spotted kiwis don't just live in New Zealand, they are the national symbol of New Zealand! Great spotted kiwi are native to the South Island of New Zealand. Subspecific information monotypic species. [30], The great spotted kiwi population started declining when European settlers first arrived in New Zealand. [17] In 1988, the species was listed as Least Concern species. Great Spotted Kiwis seem to have made a deal with evolution, as their harsh environment keeps many of their predators away. Incubation is shared more-or-less 50:50 between the parents. Nonetheless, there has been a 43% decline in population in the past 45 years, due to these predators and habitat destruction. The Okarito species inhabits just a small area on the western coast of the South Island. Great spotted kiwi live in forested mountains from sea level to 1500 metres, but mainly in the subalpine zone of 700-1100 metres. Habitat: Native forest, scrub, pakihi wetlands and tussock grassland from sea level to subalpine, but distribution patchy. No formal kohanga kiwi populations exist for great spotted kiwi.
