Kiwi have not yet died out. There are five recognised species, two of which are endangered.
There are several threats to the kiwi, which could result in this defenceless bird dying out in the future. Habitat loss and imported animals are the biggest threats. As is often the case, the introduced species have thrived, creating a threat to the native species which have less highly developed protective and defensive adaptations, having enjoyed a secure environment for thousands of years.
The kiwis' homeland, native forests and scrubs in New Zealand, are disappearing at an alarming rate due to clearing of forests for farming and agriculture, forest fires and introduction of imported animals. Due to the inability to fly, this makes kiwis vulnerable to their predators, which are usually land animals.
Not only is the loss of habitat a threat to the kiwis' food sources, but results in this small and defenceless bird having fewer places to hide from its many predators. Imported animals such as possums, livestock and deer eat trees, plant and seedlings, contributing to the clearing of forests, making it easier for mammalian and avian predators to access the habitat to prey on them.
The biggest threat to the kiwi comes from dogs and cats and other imported pets including the stoat, of all things. Being a small, flightless bird, the kiwi's defenses are extremely limited. Loss of habitat is also endangering the kiwi, not only as a threat to its food sources, but as the kiwi has fewer places to hide from its many predators. Prior to Europeans coming to New Zealand, the kiwi enjoyed a healthy population.
Theory:
Long ago, when New Zealand was still attached to other continents in Pangaea, birds that could fly lived in New Zealand. They needed to be able to fly to escape from land predators. Later on, when New Zealand split off from Pangaea, the kiwi birds were isolated. There were no longer land predators from Pangaea that could eat them.
Therefore, the kiwis began to evolve smaller and smaller wings because they didn't need to fly. They also evolved larger and stronger feet and legs so that they could walk and run on the ground easily. Kiwis evolved whiskers to feel their prey and long beaks that they use to detect prey underground. These characteristics let them fill biological niches previously occupied by mammals, like badgers.
Kiwi and penguins are both flightless birds.
Kiwi do not live in Tonga.
No. There is no species of kiwi which can fly. Kiwi are flightless birds.
Kiwi, which are small, flightless birds of New Zealand, do not live in the US.
There are no hairs on a kiwi. Kiwi are flightless birds endemic to New Zealand. As birds, they have feathers, like all birds do, although these feathers are hairlike in appearance.
They are flightless birds- they do not (and cannot) fly.

There are no common names for the kiwi, small flightless birds of New Zealand. They are simply known as kiwi.
No.Kiwi are small flightless birds which are native to New Zealand alone.Kiwifruit are vine fruit. They are not grown on a tree.
The kiwi is in the bird family. Specifically, it is classed as a ratite, a particular group of flightless birds having small wings, but without the bones in their chests having the capacity for flight muscles, which is what a bird also needs to fly.
No. Kiwi are small, flightless birds. they are not salty. Kiwifruit are also not salty, being fruit.
yes it is. The kiwi's closest relatives were the other New Zealand ratites, the Moa which was another flightless bird.
