The emblem of New Zealand, you might be surprised to be told
that the almost cartoon-like bird the Kiwi really does
exist. It is one of the few surviving relatives of the Moa
(a predecessor of the Ostrich, long extinct), which goes a
long way to explain its odd, prehistoric appearance, and experts
believe that Kiwi's existed as long as 70 million years ago.
Now, a handful of different species survive, all with slight
variations in their appearance and behaviour.
Kiwi habits and habitat
The kiwi is named after their nocturnal call which sounds
something like 'kiwi, kiwi', which is usually heard about
an hour before and after dark. They are also detectable by
the loud snuffling noises they make as they search for food.
Their appearance is very unusual, they are roughly the same
size as farmyard chickens, with earthy brown feathers, that
have a slightly rough and ragged appearance, they also have
long, downward curving bills, and stubby remnants of wings.
They are rarely seen due to their shy nocturnal habits and
seriously diminished numbers, which are declining at about
6% a year, meaning that their population approximately halves
every ten years. Sightings are also made tricky by their skills
in camouflage, they blend in perfectly with the bush, and
build burrows well in advance so foliage can grow back over
entrance before use, they then will cover the entrance carefully
with twigs on departure.
Despite their classification as birds, the kiwi bears many
similarities to a mammal, especially in their forest floor
habitat, and dependence on a highly developed sense of smell,
rather than sight as most birds are, which they use to seek
out their diet of small insects and fallen fruit. They are
flightless, nocturnal, and live in underground burrows which
they dig with their feet, and have large territories of which
they are very protective - they can be very aggressive, kicking
and scratching opponents with sharp claws.
Gender politics
Kiwis live in pairs as monogamous couples for almost all of
their lives, but the sex roles are reversed, the females are
noticeably larger and dominate the males, while it is usually
the males that incubate the eggs. They breed from May to June,
and the young leave the nest after just 2-5 weeks, while they
are still very vulnerable, which also contributes to their
diminishing numbers. If they do survive, they can live up
to 40 years.
Tribal worship
The kiwi also has special significance to the Maori,
who consider it to be the oldest child of Tane Mahuta,
the god of the forest, which means that to the Maori they
are the elders of humans, and protective of us. A Kiwi feather
cloak is a sign of chieftainship and high birth, and has great
significance as the feathers are thought to carry the spirit
of birds in them.
Where to Spot a Kiwi
Stewart Island one of best places to try and see Kiwi's
as it has one of largest population densities, plus Stewart
Island Kiwi's come out earlier than other varieties, and can
often be seen just before dusk.
