Their unique characteristic is that they have nostrils at the END of their beaks - which seems to go well with their highly developed sense of smell.

Unlike most birds, the kiwi is flightless. It falls within the infraclass Paleognathae (i.e. ratities) - a group of large Flightless Birds that also includes the Ostrich, Emu, Cassowary, and Rhea as well as the extinct Moa and Elephant Bird. It is most closely related to the extinct Elephant Bird.
They are also unusual among other birds in that, along with some raptors, they have a functioning PAIR of ovaries. In most birds, the right ovary never matures, so that only the left is functional.
Like many animals in Australia and New Zealand it probably developed so uniquely because it was ecologically isolated. (The Kiwi is only indigenous to New Zealand.)
One fact about kiwi that make these small, flightless birds different from most other birds is that fact that their nostrils are located at the far tip of their bill, giving them an excellent sense of small. Most birds' nostrils are located closer to where their bill joins their head.
Kiwi are the only known birds which have their nostrils positioned at the very tip of their beak. They have an acute sense of smell, which is most unusual in birds. They are one of very few species having shaggy feathers.
Kiwi are birds and, like most birds, their offspring are simply known as "chicks".
Kiwi Birds.
The Kiwi - This bird is flightless, and has an unusual beak: the nostrils are located at the end of the beak, unlike most other birds.
The cassowary, emu and kiwi are members of the group of flightless birds known as ratites. Ratites have wings but the bones in their chests do not have the capacity for flight muscles, which is what a bird also needs to fly.The ostrich and rhea also belong to this group.
Kiwi are ratites. The ratites are a group of flightless birds that originated in Gondwana, a prehistoric continent from which Australia, New Zealand, Madagascar, South America, Antarctica, Africa and New Guinea split off. The ratites include: * emu from Australia * cassowary from New Guinea * ostrich from Africa * rhea from South America * kiwi from New Zealand * moa (extinct) from New Zealand * Elephant bird (extinct) of Madagascar According to DNA research kiwi are most closely related to emu and cassowaries.
There are several different methods of locomotion for birds.flying (the majority of birds)walking (most birds walk as well as fly, but species such as emus, ostriches, kiwi, rheas and cassowaries are flughtless and can only walk)swim (penguins, ducks, swans)
Most birds fly or glide as their main mode of transportation. However, some birds such as penguins swim. And others, such as kiwi, walk.
Emus are not very different at all from other birds in their group. They are related to a group of birds called ratites. Other ratites include the Southern cassowary of Australia and New Guinea, the kiwi from New Zealand, the ostrich from Africa and the rhea from South America. Ratites have wings but the bones in their chests do not have the capacity for flight muscles, which is what a bird needs to fly. Although the emu does not actually weigh as much as it appears (30-45kg), its wings are also too small by comparison to lift it. Some may think that emus are different because they have hairlike feathers. However, this trait is shared by the kiwi.
Kiwi birds love to hide in bushes and in farmlands. Thus, the best habitat for this kind of bird would obviously be the scrub covered grasslands, the river lands and the bushes by the roadside. Kiwis are shy in nature, which is why even the pine forests could be of help in providing them proper shields to hide from light and predator danger. Kiwi birds live with the same partners for most of their lives, on an area of land up to 40 hectares. A kiwi bird's territory will always be dotted with burrows or shelters.
The most common name for the kiwi in New Zealand is kiwi.
