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.  If the kiwis live in an area lacking predators, they will come out in the day.  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. , 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 .

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.  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.

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.  The egg-laying season is between August and January.  The main threat is from invasive predators including mustelids, brush-tailed possum Trichosurus vulpecula, feral cats, dogs and pigs The most threatened populations are in the southern areas of the species' range.
