The bird has a roundish built and can grow about 16 inches to 18 inches tall, weighing around seven pounds on average. The bird species vary in size and are found in different locations, mostly in forests. The bird locates its nest in thick vegetation, burrows and hollow logs.

One unique trait of the kiwi bird is that is cannot fly as its wings do not contain any muscle to help it. However, the bird has powerful feet, making it a fast runner, allowing it move around quickly to avoid danger from predators.

The nostrils are useful in probing and sniffing out foods such as insects, worms, fallen fruits, seeds, small worms and invertebrates. Its sense of smell is highly developed and the bird uses it to the best advantage-seeking for foods. The bird is nocturnal-being active at night to keep away from predators.

The Kiwi Bird is one of the most interesting bird species in the world, mostly due to its unusual characteristics and weird looks. This bird originated in New Zealand, a country that uses it as its national icon to this day.if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[580,400],'thepricer_org-medrectangle-3','ezslot_2',124,'0','0'])};__ez_fad_position('div-gpt-ad-thepricer_org-medrectangle-3-0');

Kiwi (/ˈkiːwiː/ KEE-wee)[4] are flightless birds endemic to New Zealand of the order Apterygiformes.The five extant species fall into the family Apterygidae (/ˌæptəˈrɪdʒədiː/) and genus Apteryx (/ˈæptərɪks/).[5] Approximately the size of a domestic chicken, kiwi are the smallest living ratites (which also include ostriches, emus, rheas and cassowaries).

DNA sequence comparisons have yielded the conclusion that kiwi are much more closely related to the extinct Malagasy elephant birds than to the moa with which they shared New Zealand.[6] There are five recognised species, four of which are currently listed as vulnerable, and one of which is near-threatened. All species have been negatively affected by historic deforestation, but their remaining habitat is well-protected in large forest reserves and national parks. At present, the greatest threat to their survival is predation by invasive mammalian predators.

Kiwi eggs are one of the largest in proportion to body size (up to 20% of the female's weight) of any order of bird in the world.[7] Other unique adaptations of kiwi, such as their hairlike feathers, short and stout legs, and using their nostrils at the end of their long beak to detect prey before they see it, have helped the bird to become internationally well-known.

Although it was long presumed that the kiwi was closely related to the other New Zealand ratites, the moa, recent DNA studies have identified its closest relative as the extinct elephant bird of Madagascar,[6][15] and among extant ratites, the kiwi is more closely related to the emu and the cassowaries than to the moa.[6][16]

Research published in 2013 on an extinct genus, Proapteryx, known from the Miocene deposits of the Saint Bathans Fauna, found that it was smaller and probably capable of flight, supporting the hypothesis that the ancestor of the kiwi reached New Zealand independently from moas, which were already large and flightless by the time kiwi appeared.[17]

Their adaptation to a terrestrial life is extensive: like all the other ratites (ostrich, emu, rhea and cassowary), they have no keel on the sternum to anchor wing muscles. The vestigial wings are so small that they are invisible under the bristly, hair-like, two-branched feathers. While most adult birds have bones with hollow insides to minimise weight and make flight practicable, kiwi have marrow, like mammals and the young of other birds. With no constraints on weight due to flight requirements, brown kiwi females carry and lay a single egg that may weigh as much as 450 g (16 oz). Like most other ratites, they have no uropygial gland (preen gland). Their bill is long, pliable and sensitive to touch, and their eyes have a reduced pecten. Their feathers lack barbules and aftershafts, and they have large vibrissae around the gape. They have 13 flight feathers, no tail and a small pygostyle. Their gizzard is weak and their caecum is long and narrow.[26]

The eye of the kiwi is the smallest relative to body mass in all avian species, resulting in the smallest visual field as well. The eye has small specialisations for a nocturnal lifestyle, but kiwi rely more heavily on their other senses (auditory, olfactory, and somatosensory system). The sight of the kiwi is so underdeveloped that blind specimens have been observed in nature, showing how little they rely on sight for survival and foraging. In an experiment, it was observed that one-third of a population of A. rowi in New Zealand under no environmental stress had ocular lesions in one or both eyes. The same experiment examined three specific specimens that showed complete blindness and found them to be in good physical standing outside of ocular abnormalities.[27] A 2018 study revealed that the kiwi's closest relatives, the extinct elephant birds, also shared this trait despite their great size.[28]

Unlike virtually every other palaeognath, which are generally small-brained by bird standards, kiwi have proportionally large encephalisation quotients. Hemisphere proportions are even similar to those of parrots and songbirds, though there is no evidence of similarly complex behaviour.[29]

Before the arrival of humans in the 13th century or earlier, New Zealand's only endemic mammals were three species of bat, and the ecological niches that in other parts of the world were filled by creatures as diverse as horses, wolves and mice were taken up by birds (and, to a lesser extent, reptiles, insects and gastropods).[30]

The kiwi's mostly nocturnal habits may be a result of habitat intrusion by predators, including humans. In areas of New Zealand where introduced predators have been removed, such as sanctuaries, kiwi are often seen in daylight. They prefer subtropical and temperate podocarp and beech forests, but they are being forced to adapt to different habitat, such as sub-alpine scrub, tussock grassland, and the mountains.[26] Kiwi have a highly developed sense of smell, unusual in a bird, and are the only birds with nostrils at the end of their long beaks. Kiwi eat small invertebrates, seeds, grubs, and many varieties of worms. They also may eat fruit, small crayfish, eels and amphibians. Because their nostrils are located at the end of their long beaks, kiwi can locate insects and worms underground using their keen sense of smell, without actually seeing or feeling them.[26] This sense of smell is due to a highly developed olfactory chamber and surrounding regions. It is a common belief that the kiwi relies solely on its sense of smell to catch prey but this has not been scientifically observed. Lab experiments have suggested that A. australis can rely on olfaction alone but is not consistent under natural conditions. Instead, the kiwi may rely on auditory and/or vibrotactile cues.[31]

Once bonded, a male and female kiwi tend to live their entire lives as a monogamous couple. During the mating season, June to March, the pair call to each other at night, and meet in the nesting burrow every three days. These relationships may last for up to 20 years.[32] They are unusual among other birds in that, along with some raptors, they have a functioning pair of ovaries. (In most birds and in platypuses, the right ovary never matures, so that only the left is functional.[26][33][34])

It was believed that the large eggs were a trait of much larger moa-like ancestors, and that kiwi retained large eggs as an evolutionarily neutral trait as they became smaller. However, research in the early 2010s suggested that kiwi were descended from smaller flighted birds that flew to New Zealand and Madagascar, where they gave rise to kiwi and elephant birds. The large egg is instead thought to be an adaptation for precocity, enabling kiwi chicks to hatch mobile and with yolk to sustain them for two and half weeks. The large eggs would be safe in New Zealand's historical absence of egg-eating ground predators, while the mobile chicks would be able to evade chick-eating flying predators.[41]

Efforts to protect kiwi have had some success, and in 2017 two species were downlisted from endangered to vulnerable by the IUCN.[51] In 2018 the Department of Conservation released its current Kiwi Conservation Plan.[50]

North island brown kiwi were introduced to the Cape Sanctuary in Hawke's Bay between 2008 and 2011, which in turn provided captive-raised chicks that were released back into Maungataniwha Native Forest.[67]

In 2004, anti-1080 activist Phillip Anderton posed for the New Zealand media with a kiwi he claimed had been poisoned. An investigation revealed that Anderton lied to journalists and the public.[70] He had used a kiwi that had been caught in a possum trap. Extensive monitoring shows that kiwi are not at risk from the use of biodegradable 1080 poison.[71]

Habitat destruction is another major threat to kiwi; restricted distribution and small size of some kiwi populations increases their vulnerability to inbreeding.[49] Research has shown that the combined effect of predators and other mortality (accidents etc.) results in less than 5% of kiwi chicks surviving to adulthood.[48]

In 1813, George Shaw named the genus Apteryx in his species description of the southern brown kiwi, which he called "the southern apteryx". Captain Andrew Barclay of the ship Providence provided Shaw with the specimen. Shaw's description was accompanied by two plates, engraved by Frederick Polydore Nodder; they were published in volume 24 of The Naturalist's Miscellany.[75]

In 1851, London Zoo became the first zoo to keep kiwi. The first captive breeding took place in 1945.[76] As of 2007 only 13 zoos outside New Zealand hold kiwi.[77] The Frankfurt Zoo has 12, the Berlin Zoo has seven, Walsrode Bird Park has one, the Avifauna Bird Park in the Netherlands has three, the San Diego Zoo has five, the San Diego Zoo Safari Park has one, the National Zoo in Washington, DC has eleven, the Smithsonian Conservation Biology Institute has one, and the Columbus Zoo and Aquarium has three.[78][79] 781b155fdc
