Kiwis are unique to New Zealand. They are nocturnal and flightless. There are five kinds of kiwi - three closely related Brown Kiwis, the Little Spotted Kiwi and the Great Spotted Kiwi. The kiwi’s long slender bill has nostrils at the lower end, so that it can detect worms, insects and grubs. Despite its awkward appearance, a Pictures of Kiwi Birds New Zealand can outrun a human.
The kiwi is New Zealand's national icon and part of our image world-wide. New Zealanders have been "Kiwis" since the days of the First World War. It's a nickname bestowed by fellow Australian soldiers, and it stuck. Today our identity as Kiwis is based around our national bird Pictures of Kiwi Birds New Zealand.
It's a curious bird, the kiwi: It cannot fly, has loose, hair-like feathers and long whiskers. Largely nocturnal, it burrows in the ground, is the only bird known to have nostrils at the end of its bill and literally sniffs out food. It also has one of the largest egg-to-body weight ratios of any bird - the egg averages 15per cent of the female's body weight ( compared to two per cent for the ostrich) Pictures of Kiwi Birds New Zealand.
The kiwi is related to the ostrich of Africa, the emu of Australia and the now-extinct moa of New Zealand. Females are larger than males and with brown kiwi, the male does most of the egg incubating. Kiwis live in pairs and mate for life, sometimes as long as 30 years Pictures of Kiwi Birds New Zealand.
Surveys through the 90s show numbers throughout mainland New Zealand dropping by an alarming 5.8 per cent a year. There are now about 75,000 kiwis left. If the present rate of decline continues numbers will be down to 50,000 by the year 2006 and many of these will be on protected off-shore islands Pictures of Kiwi Birds New Zealand.
The brown kiwi is still widespread in the central and northern North Island, but the little spotted kiwi survives only on off-shore islands. Around 1000 of them live on Kapiti Island, with transferred little spotted kiwi now well-established on Hen Island and Red Mercury Island in the Hauraki Gulf, Long Island in the Marlborough Sounds, and recently on Tiritiri Matangi in the Hauraki Gulf Pictures of Kiwi Birds New Zealand.
Introduced predators are the biggest threat. Stoats and cats kill 95 per cent of kiwi chicks before they are six months old. Adult kiwi are often killed by ferrets and dogs.
The Department of Conservation strategy to preserve the kiwi is fourfold: to protect nests in the wild from predators; to raise chicks in captivity and release them into the wild when they are able to defend themselves from stoats and cats; ongoing research into genetics, breeding and habitat requirements, and seeking help from the community, especially in areas where kiwi are still found on private land.
Kiwi advocacy in Northland is a good example of this. Northland is the last major stronghold of the North Island brown kiwi and the birds there have three official advocates. Another advocate is employed on the Coromandel Peninsula Pictures of Kiwi Birds New Zealand.
In the early stages their objectives were to provide information and raise awareness about the threats to our national icon. Now advocates are more focused on supporting the efforts of private landowners and communities living near critical kiwi populations and lobbying for legislative protection for kiwi habitat and better control of kiwi predators. These kiwi advocates, driving their distinctively marked vehicles, have become known as the "kiwi lady" or the "kiwi man".
For New Zealanders, the kiwi is not just another bird and saving the kiwi is not just a matter of concern for scientists and conservationists. To Maori and Pakeha alike, kiwi are a taonga, or treasure and part of our unique identity Pictures of Kiwi Birds New Zealand.
The Department of Conservation acknowledges the support of Bank of New Zealand in helping to fund the Kiwi Recovery Programme since 1991.
In November 2002, Bank of New Zealand Kiwi Recovery Trust was set up by DOC and the Bank of New Zealand to strengthen the funds and resources available to protect kiwi nationally Pictures of Kiwi Birds New Zealand.
Pictures of Kiwi Birds New Zealand is nocturnal, tail-less and flightless. They are the only known bird to have external nostrils at the base of their long beaks and their sense of smell is very finely tuned. It locates the insects, grubs and spiders it eats by sniffing among the leaves, moss and rotting wood on the forest floor leaving characteristic bore marks. They tap the ground with their beaks and scrape away forest litter with their feet searching for food by pushing their beak about 15 cm into the ground and probing for insects, worms and snails. They also eat the berries from some native trees. Sometimes they make a snuffling sound, as they expel air through their nostrils while they feed.
Pictures of Kiwi Birds New Zealand are burrowers and often move to a new burrow each day. The little spotted kiwi and the brown kiwi tend to use simple one-entrance burrows, but the great spotted kiwi puts time and effort into constructing a labyrinth of tunnels. Kiwi live in pairs, as couples, all their lives. Male kiwi fight vigorously for a mate and the female occasionally kicks her smaller partner when warding off his unwanted advances. About every third day, the pair shelter together in the same burrow. During the night when they are foraging for food or patrolling their territory, they call to each other. The calls of the male and female are quite distinct: he utters prolonged shrill whistles, while she has a lower, hoarser cry.
Pictures of Kiwi Birds New Zealand are very strong and often extremely bad tempered. Adult birds use their razor sharp claws to defend themselves. Extremely territorial, they protect their "patch", which can be as large as 40 hectares, by calling, or chasing the intruder and kicking it. When alarmed or feeling aggressive, kiwi make noises that range from a growl to a hiss, along with loud bill-snapping.
Pictures of Kiwi Birds New Zealand have only remnants of wings, and like the moa to which they are related , lack a keel on the breastbone for attachment of flight muscles. Though kiwis have weak eyesight, long bristles around there mouths help them feel their way through the undergrowth at night.
The nest is a burrow or depression under tree roots or a hollow log. It lays a clutch of eggs of 1 or 2 very large off-white eggs laid at an interval of 10-30 days. The eggs are about 180mm long and 80mm in diameter - six times as large as would be normal for a bird of its weight and weighing about 20% of the female's body.. The incubation period is 72-80 days, usually by the male Pictures of Kiwi Birds New Zealand.
Throughout the incubation period the male covers the nest with sticks and leaves each night and goes off to search for food. Sometimes he also leaves it during the day. This makes the eggs vulnerable to predation by mammals and sometimes weka. For the first week after it hatches, the kiwi chick relies on the yolk sac from its egg for food. At one week old, it emerges from the nest for the first time. It looks just like a small adult kiwi. For more than two weeks the male and the chick share the burrow during the day, while at night both parents stay close enough to the chick to protect it Pictures of Kiwi Birds New Zealand.
The male kiwi leaves the nest when the chick is about three months old. Soon after, the chick leaves the nest and for the next few weeks, finds its own shelter during the day. The young kiwi feeds at night, keeping its distance from its parents, who seem to tolerate its presence less Pictures of Kiwi Birds New Zealand.
By the following spring the chick has moved out of the parents territory altogether. It moves around, staying in a variety of places where it may be chased out by other kiwi, until it finds an empty territory.
Even scientists in the know have difficulty the sex of Kiwis and staff at the Queenstown Kiwi and Birdlife Park were a tad surprised when "Baldric" hatched an egg. So the Massey University and a bit of DNA sampling are trying to improve on the traditional methods used - bill length, call and size. I think I would rather leave it a surprise .Pictures of Kiwi Birds New Zealand...
The Kiwi survived for so many million of years because its protective colouration and hidden lifestyle protected it from the old native enemies - threats from the air by the giant eagle Harpagornis or the huge harrier, both now extinct themselves. But the kiwi was in no way equipped to protect itself against the threats from the ground - stoats, ferrets, weasels, possums, pigs, dogs, cats and humans Pictures of Kiwi Birds New Zealand.
The most ancient of New Zealand’s birds, the kiwi evolved 70 million years ago from a flightless ancestor from the great southern continent of Gondwana. It’s a member of the ratite group, and related to the ostrich, emu and rhea as well as the now extinct New Zealand moa Pictures of Kiwi Birds New Zealand.
This bird, even if it is not very often seen, is well known. It has given its name to New Zealanders, who are called "Kiwis" the world over. Yet all this time the bird has been a relatively secretive, nocturnal species seldom seen in the wild state Pictures of Kiwi Birds New Zealand.
Kiwis are relatively long - lived birds. Branding studies have not been going long enough to give a good indication of life expectancy, but 20 - 30 years is probable. Several brown and little spotted kiwis have lived in captivity for 20 years or more and one North Island brown is approaching 40.
There are two species of Kiwis in New Zealand. Brown Kiwis are found in forested areas in the North Island, Fiordland, South Westland and Stewart Island. Spotted Kiwis are found on offshore islands and forests in the North of the South Island Pictures of Kiwi Birds New Zealand.
There are six varieties of the kiwi; the Great Spotted, the Little Spotted, the North Island Brown, the Okarito Brown, the Stewart Island Brown and the The Haast Brown Pictures of Kiwi Birds New Zealand.
The Maori hunted the birds at night with the aid of dogs and torches. The skins and feathers were made up in to cloaks which were highly prized. The Maori believed that the kiwi was under special protection of the god Tane, and they called it Te manu a Tane - the bird that Tane hid Pictures of Kiwi Birds New Zealand.
