How long can kiwi live for?
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.
Kiwi are feisty and aggressive. Some people think kiwi are timid and shy – in fact, they are super strong, territorial and can be extremely bad tempered. Adult birds use their razor-sharp claws as weapons and a couple of slashes can draw blood.
- Kiwi (/ˈkiːwi/ KEE-wee) or kiwis are flightless birds native to New Zealand, in the genus Apteryx and family Apterygidae.
- There are about 68,000 kiwi left. The closest relatives to kiwi today is the elephant bird from Madagascar. They are also related to emus and cassowaries of Australia, and the extinct moa of New Zealand.
- New Zealand's Little Spotted Kiwi Birds are in More Trouble than We Thought. Kiwi are flightless, nocturnal birds that are native to New Zealand. There are five recognised species of kiwi, and with 400 remaining individuals, the rarest is the critically endangered Rowi (Apteryx rowi) of New Zealand's Okarito forest.
- Its smooth, thin, white or greenish-white shell is about 120 millimetres long and 80 millimetres in diameter. Because of their size, kiwi could be expected to lay an egg about the size of a hen's egg. In fact, the kiwi egg is six times as big as normal for a bird its size.
- Although not listed as endangered by any Australian state, the koala population has been devastated over the last hundred years and is currently under great threat due to urbanisation and massive, uncontrolled habitat destruction.
- Kiwi are flightless – their Latin species name is Apteryx, which means wingless. They belong to an ancient group of birds that can't fly – the ratites. Because they can't fly, how they arrived in New Zealand is not completely clear.

- Is a penguin a bird? However, penguins are classified as birds (Aves) in zoological terms. They are black and white flightless seabirds of the family Spheniscidae which are found in the southern hemisphere, chiefly in the Antarctic (although several species live in more temperate regions).
- So, to recap, chickens are bad at flying because their direct ancestor was bad at flying, because they're adapted for spending time on the ground. Chickens are not a natural species; they were created by breeding the red jungle fowl into a new organism.
- 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.
