Special Adaptations Kiwi birds have been called a genetic leftover. Their characteristics seem very odd to us probably due to the fact that they haven't evolved much at all. They are suspected to be about 8 million years old. That's 7 million years older than humans. Due to New Zealand's isolated environment, it has been safe from predators and hasn't needed to do much adapting. They just hang around.
Kiwi birds cannot fly.
The kiwi digs up and chows on worms.
A kiwi bird is almost blind, meaning that it can see only to about six feet distance at night and less than two feet during the day.
This bird uses the nostrils to be able to hunt.
Kiwi birds lay eggs that are the size of ostrich eggs. This means that these birds lay enormous eggs for their own size.
Kiwi birds are believed to be more than 8 million years old.
A kiwi weights about 800 g to 1 kg. Its height is of about 50 cm.
The normal diet of a kiwi includes worms, spiders, bugs, grubs and fruit, as well as freshwater and frogs.
There actually are five kiwi species. They include North Island Brown Kiwi, Great Spotted Kiwi, Lesser Spotted Kiwi, Rowi, and Tokoeka .
A female kiwi is larger than a male.

The elite distinction of kiwi is shown by all species being placed in their own family - Apterygidae; and being the only members of the order Apterygiformes.
Kiwi have no tail and only tiny vestigal wings hidden beneath their feathers. It is the smallest member of the ratite family, related to the much larger, moa, emu, ostrich, cassowary and rhea. One theory prompted by the kiwi's very large egg, suggests it may have had a larger body size at one time.
The origin of kiwi is disputed by different scientific studies. Research based on morphological data defining the ratite family tree, defines kiwi as closely related to moa by ten skeletal similarities
Moa,or Dinornis, an extinct flightless bird of New Zealand. There were about 20 species of moas. Depending on species, they ranged in height from 3 to 13 feet (0.9 to 4 m) and in weight from 30 to 520 pounds (14 to 236 kg). The moa had a short, stout bill, a small head, and a long neck. The feet were large and broad. Silky brown or black-and-white feathers covered the body and the upper half of the legs; the head, neck, lower half of the legs, and feet were bare. Wings were small or absent. Moas fed chiefly on plants.
Most species of moas became extinct before 1400; a few survived into the 1600's. The causes of these extinctions are unknown; one probable cause is indiscriminate hunting by the Maoris, the earliest known inhabitants of New Zealand.
The largest species of moa was Dinornis maximus; the smallest. Anomalopteryx oweni. Moas made up the family Dinornithidae.
There are currently five different kinds of Kiwi birds. These include the Great Spotted Kiwi, the Little Spotted Kiwi, the Brown Kiwi, the Rowi Kiwi and the Tokoeka Kiwi. The classification of Kiwis is always evolving and changing, however.

Do they taste sort of like a strawberry too?

Yes a bird to be proud of and a protected species - as an immigrant to NZ from the UK I'm still fascinated with the variety of bird and plant life and so far the Pukecu is my favourite - as an artist I have done a painting of a particularly friendly one that used to come to one of the local cafes' every day and be fed corn by the owner.
Beautiful NZ - Paradise found! SSSHHHH............! Keep it quiet!
S&F for the Kiwi.

You should probably mention Hapagornis moorei as well, since you showed a picture of it.
Now, that is something to be proud of. I've excavated some talons on a dig at Bell Hill, near Pyramid Valley.
Kiwi are awesome too. Nearly ran one over on the Rai Saddle on the way to the Globe Progress mine near Reefton. They're not really friendly though, and their feet are capable of eviseration. Unfortunately, they're not adapted to mustelids.
Kiwi: eats shoots and leaves.

Here's another tit-bit I bet only few people knew: The Kiwi is the bird with the shortest bill/beak.
Biologists generally measure a bird's beak from the tip to the nostril - and seeing that the kiwi's nostrils are just about on the tip of its beak, it technically has the shortest beak of all birds.edit on 14-12-2012 by Gemwolf because: Missing word

We've got Moa bones with obvious eagle predation. It goes to follow that they would possibly have preyed on humans, but I'm not aware of any human bones found in aeries. they were big suckers, but died out when their main food source was hunted to extinction/became extinct.
