1) The kiwi bird is a terrestrial flightless bird found only in New Zealand. Kiwi bird populations have been severely damaged by the introduction of mammalian predators to New Zealand. Kiwis are nocturnal animals. The females lay a single egg that can be up to 1/3 of her body mass. This mode of reproduction makes kiwis extra vulnerable to population crash. The birds probe with their long bills to collect food, mainly worms.
2) The kiwi bird is considered by many to be the national symbol of new zealand and so holds a high importance to the new zealand people. It is also considered one of the most distinctive birds because of its flightless nature and atrophied wings, along with its odd almost fur like plumage.
3)It is thought that kiwis evolved from a group of birds in Australia and immigrated to new zealand via a land bridge before the late Cretaceous.
