"Great Barrier (Island)
remains one of the largest areas in New Zealand
where mustelids (weasels, stoats, and ferrets)
have not become established.
This is very
significant for preserving existing species of birds
for future ecological restoration. On the mainland, mustelids have
accelerated the decline of many native birds (for example
kiwi, various petrels, brown teal, kakapo and kaka),
which had already been greatly diminished by European rats and feral
cats. The continued existence of black petrel, brown teal,
banded rail and kaka on Great Barrier today is probably mainly
due to the lack of mustelids."

Many other birds found here have eluded our camera so far.
The property is prime habitat for the Brown Teal Duck and Banded Rail,
just sit and watch and you will see them.
Regular visitors are groups of Kaka - Nestor septentrionalis
- the New Zealand Bush Parrot and also Kakariki : Red-crowned Parakeet
- Cyanoramphus
novaezelandiae
and Yellow-crowned Parakeet -
Cyanoramphus auriceps. The dawn chorus is punctuated by
the song of the Tui or Parson Bird - Prosthemadera novaeseelandiae
and the "woosh woosh" sound of primitive flight feathers reveals fat
Kereru - Wood Pigeon, -
Hemiphaga novaeseelandiae
who are often seen feeding on Puriri berries.
These are some of the rarer species seen on the property.
Among the more common native birds are
Kotare - the Kingfisher -
Halcyon sancta,
Piwakawaka - the Fantail -
Rhipidura fulginosa,
and the ever present Pukeko -
Purple Moor Hen -
Porphyrio porphyrio melanotus,
who are most resplendent in royal purple with brilliant white undertail
plumage during courtship. Frequently heard is Riroriro - the Grey
Warbler -
Gerygone igata
and, at night, Ruru - the morepork or native owl -
Ninox novaeseelandiae.
Of course, being New Zealand, we also have a number of introduced
species; the Skylark, Blackbird, Songthrush and Sparrow to name some,
having been brought
here by European settlers to make it more like home.
The Okiwi Valley stretches from bush-clad mountain to the Pacific
Ocean,
with a graduation of all the differing habitats in between.
This transect, from 335 metres altitude, is over a mere 5 kilometres
and the property sits halfway between mountain and sea.
To venture out it is 2 km up the road to the top of the hill,
2km down the road to the estuary or 5km by an alternative road to the
ocean beach.
Looking down on the Okiwi Valley from the South
is the highest point on the island, Hirakimata or Mount Hobson.
This is the stronghold and breeding ground of the Taiko or black petrel
- Procelllaria
parkinsoni.
These formerly bred on many inland ranges of the mainland,
but are now known to breed only on Great and Little Barrier Islands.
Just 25km West lies Little Barrier Island where recently the New
Zealand Storm Petrel -
Oceanites maorianus (Pealeornis maoriana),
thought for 100 years to have been extinct, was
photographed and confirmed.
The property is not far from the swampland of the upper estuary
where the Matuku - Australasian Bittern -
Botaurus poiciloptilus,
whose booming can resonate throughout the valley, is master of
camouflage.
Most secretive are the rarely seen Rails;
Puweto - the Spotless Crake -
Porzana tabuensis plumbea,
recently heard in the Kaitoke wetland
and Koitareke - the Marsh Crake -
Porzana pusilla.
At low tide the Whangapoua Estuary exposes a vast shallow area of flats
that
nourish numerous waders including migratory species such as the Kuaka
- Bar-tailed Godwit -
Limosa lapponica.
A short drive down Mabey Road takes you to Whangapoua Beach
where three species of particular rarity are found. The New Zealand Dotterel,
The Variable
Oystercatcher
and the Fairy Tern -
Sterna nereis davisae.
"The range of coastal and shore birds on Great Barrier is similar to
other parts of northern New Zealand. These species include pied, black
and little black shags, red-billed gulls, white-fronted and Caspian
terns,
reef and white-faced herons, variable and South Island pied
oystercatchers,
New Zealand and banded dotterels, wrybill, pied stilts and several
species
of migrant Arctic waders, including bar-tailed godwit and golden
plover."

"This year the red-crowned parakeet or kakariki became the
73rd New
Zealand bird species to join the global "Red List" of birds threatened
with extinction.
Like so many other birds, kakariki fall victim to predation by rats,
stoats and possums."
