What are the threats to the takahe?
Natural hazards influencing the Fiordland takahē population include avalanches and cold climate. Modern threats include predation by introduced stoats, and competition for food from introduced red deer.
Why are NZ birds endangered?
NZ has the most endangered birds When New Zealanders introduced mammalian pests to New Zealand and began to change the land, they killed off many unique species. At least 3,742 species of plants and animals are now at risk or threatened with extinction. Only 6% of these species are currently in conservation programmes.
How does the weather affect takahe?
Severe weather can threaten the takahē population. For example, severely cold winters and avalanches can adversely affect population numbers. Because of this, the Department of Conservation has established a second wild population of takahē in Kahurangi National Park.

What are some takahe adaptations?
Takahē and kiwi have vestigial wings. After many years of not requiring the use of flight, they evolved a larger body size and lost the ability to fly. Kiwi plumage blends in with forest undergrowth to allow them protection from predators through camouflage.
What conditions allowed Takahe to survive?
Wild takahē populations live in harsh alpine conditions. They feed on alpine grass species called snow tussock. They use their strong beaks to cut and strip the tough blades. When winter snow covers the tussock, takahē move down to forested areas for shelter and to feed on fern rhizomes.
Why are Kiwis endangered?
Kiwis are being driven to extinction by three main threats – predators, lost habitat and people.
Are takahe endangered?
Endangered (Population increasing)
Takahe/Conservation status
Are takahe critically endangered?
Today takahē are classified as Nationally Vulnerable, with a population of just over 400 birds. DOC’s dedicated Takahē Recovery Programme is working hard to grow this number and establish self-sustaining wild populations within their former range, the native grasslands of the South Island.
Why did the North Island takahe go extinct?
Localities ranged in altitude from sea level to ~1000 m. North Island takahe bones have been found in seven midden deposits from South Taranaki and Manawatu, confirming that North Island takahe were captured and eaten by Maori. This is presumed to be the main cause of its extinction.
What adaptations do takahe have?
Why did the Takahe bird go extinct in New Zealand?
Takahē once roamed across the South Island, but pressures from hunting, introduced predators, habitat destruction and competition for food led to their decline. After being presumed extinct for nearly 50 years, the takahē was famously rediscovered in 1948.
What are the threats to the Takahe in New Zealand?
Mammalian predators are the biggest threat to takahē. In 2007, there was a stoat plague that halved the takahē popluation in the Murchison Mountains. Deer love to browse on the same tussock species as takahē do.
How old can a takahe be in captivity?
In captivity, takahē have lived to be over 25 years old. The takahē was once thought to be extinct, but in the 1948 it hit world headlines when an Invercargill doctor, Geoffrey Orbell, rediscovered the bird high in the tussock grasslands of the remote Murchison Mountains, Fiordland.
What kind of habitat does a takahe live in?
Adult feeding a chick. The takahē is a sedentary and flightless bird currently found in alpine grasslands habitats. It is territorial and remains in the grassland until the arrival of snow, when it descends to the forest or scrub.
