There
were only 4 official sightings of takahe between 1800 and 1900,
so by 1930 the takahe was presumed extinct.
But
there was a man, Dr Geoffrey Orbell, who believed there were still
takahe in the valleys of the Murchison Mountains. He spent his weekends
and holidays tramping through the valleys with his friends in search
of the takahe. It took many trips and LOTS of walking, but he found
them!

Dr Geoffrey Orbell rediscovered the takahe on the 20th
of November 1948. It turned out there were about 250 takahe living
in the valleys of the Murchison Mountains and the neighbouring
ranges.
The valley
where Dr Orbell rediscovered the takahe was named Takahe
Valley and the Lake nearby was named 'Lake Orbell'
see where they are on the Takahe
Map.

reading "Saving New Zealands Endangered Birds"
by Rod Morris and Hal Smith, 1995. This book has a chapter about
the takahe. It tells the wonderful story of Dr Orbells discovery
it was an amazing adventure.
Takahe
once lived throughout New Zealand... their bones have
been found in maori middens. Like the moa, their numbers shrank
in the face of maori hunting, but unlike the moa, the takahe did
not become extinct. Instead they survived in the bleak, remote
Murchison mountains, safe from the hunters.
Isolation
saved the takahe but even in their remote mountains they became
threatened , this time by introduced stoats and deer, which ate
the takahe's favourite tussock grasses.
Nowadays,
while the takehe population in the Murchison mountains remains,
new populations are being established on predator-free islands
like Maud and Kapiti, and the takahe are thriving in the lowlands
where they used to live.

about the takahe
The takahe is only found in New Zealand, which means it is
endemic to New Zealand.
It is an endangered species
Another Maori name for the takahe is moho
The takahe is an 'old' New Zealander, descended from the Australian
pukeko-like ancestor. The takahe became big and flightless and
slow breeding in New Zealand. Its relation, the present pukeko
only arrived from Australia a few thousand years ago.
In 1847 the takahe was given the scientific name Notornis
mantelli' after the scientist Walter Mantell, who discovered
takahe bones in the North Island. However the takahe is now
recognised in the same grouping as the pukeko, so its scientific
name changed to 'Porphyrio mantelli hochstetteri'.
Takahe have lived to be over 20 years old in captivity, but
few wild birds reach this age
Takahe are related to the pukeko (another native New Zealand
bird)
Takahe wings are not used for flying, but they are used during
courtship and to show aggression
It is the largest living member of the rail family of birds
Once found in both the North and South Islands, takahe now
only live in the wild in the Murchison and Stuart Mountains
in Fiordland National Park.
Small numbers of takahe have been relocated to four offshore
islands - Maud, Mana, Kapiti and Tiritiri Matangi
Takahe Valley in Fiordland National Park was named after the
takahe
In 1953 a 500 kilometre square area within Fiordland National
Park was set aside especially for takahe conservation
Fiordland National Park was set up in the same year Dr Orbell
rediscovered the takahe - 1948. (Learn more about New Zealands
National
Parks)
What does a takahe do all day?
They
eat and eat and eat and eat. Like many browsing creatures they
spend most of the day eating to get enough nourishment from their
food source. The Murchison Mountains takahes preferred food
is three varieties of tussock grass - broad leafed snow tussock,
mid-ribbed snow tussock and curled snow tussock. They eat the
fresh, juicy part at the bottom of each blade, where the sugar
and protein is found.
Takahe also eat fern roots, but generally only in winter when
the tussock is snowed in. Sometimes takahe eat the mountain daisy,
Celmisia petriei, other grasses, sedges and herbs and moths.
Takahe parents will feed invertebrates to young chicks to give
them more protein.
Takahe living on off-shore islands eat all sorts of grasses.
Takahe are quite adaptable to other environments - and remember
that takahe did used to live throughout New Zealand.
There's some good pictures of takahe eating tussock grass
in 'Takahe' By Roger Lavers and Jim Mills. Published by John McIndoe,
1984.
Takahe chicks
A
female takahe needs to be at least two years old before she will
have chicks. When takahe find partners to have chicks with, they
will usually mate for life.
Breeding begins in October. Takahe build a nest on the ground
amongst vegetation where they can hide a nest. Two eggs are usually
laid, but sometimes its 1 or 3, between mid October and
mid December. The takahe parents take turns at incubating the
eggs, which take around 30 days to hatch.
Takahe
chicks have black fluffy down (baby feathers) and a black beak
they get their red beak and beautiful green and blue feathers
when they get bigger. Both parents feed them for about three months,
then they have to get their own food. The chicks learn how to
feed themselves by following and copying their parents.
The Department of Conservation traps stoats during spring and
summer while the takahe are nesting and when chicks are young.
DOC traps the stoats to stop them eating the takahe eggs and chicks.
There are some photo's of takahe chick rearing in 'Takahe' By
Jenny Jones. Published by Heinemann Education, 1997.
