ven if you are only passing
through Auckland, take the trouble to explore the offshore islands, where there can still
be seen birds that have now largely disappeared elsewhere. 
The saddleback is found on Tiritiri Matangi Island in
Auckland's Hauraki Gulf
Check with the Department of Conservation, familiarly known as DOC, or
Gulf Harbour Ferries and see if they have a trip going to Tiritiri Matangi, an island not
far off Auckland's North Shore. This island was once farmland, but is in the process of
being turned back into forest. Volunteer groups have so far planted over 300,000 native
trees and eventually it is planned to have the entire island in forest once again. To
those accustomed to the glorious mix and match of prime native forest, it is a little
unusual to see such regimented planting of native trees. Still, given time, this look will
disappear; already a number of native birds including kakariki (parrot), whiteheads and
tieke (saddleback) have been successfully introduced to Tiritiri Matangi along with
stitchbirds, robin, takahe, the little spotted kiwi and most recently kokako.
This is probably the only place where you can now conveniently see the
tieke in the wild. It moves through the bush with a rapid, almost frenetic motion, seldom
pausing in its search for food. Ornithologist Dr Waiter Oliver described the related South
Island species as:
... a noisy, active bird progressing by what may be described as
long hops or short flights. It appears on the scene to the accompaniment of its shrill
notes, moves restlessly about for a few moments and disappears as quickly as it came.
Anyone watching the tieke for any length of time would probably think
it too quick for any predator to catch, but its roosting and nesting habits were its
undoing. It spends the night on low perches on or near ground level and nests in holes
easily accessible to foraging rats. DOC workers .have been trying to condition it to use
nestboxes, but it is a little optimistic to try and cram a few million years of evolution
into a couple of lifetimes. It will be interesting to see what association the tieke will
eventually form with the whitehead (popokatea), on Tiritiri, as early observers noted that
the foraging flocks of whitehead were accompanied by a pair of tieke which acted as
guardians of sorts - indeed, they are said to take their name from tiaki, the
Maori name for guardian.
Another island worth visiting is Great Barrier. Called Aotea (the long,
white cloud) by the Maori, the island was home to kokako, brown teal and kiwi although it
seems that the kokako and kiwi have now gone. The island was once covered in extensive
stands of kauri, but only an area of about 40 hectares near the summit of Mt Hobson
remains. The largest sawmill in the Southern Hemisphere operated from the Barrier and logs
were floated in for milling from the Coromandel and even from the Bay of Islands. Today
the only remnant of the mills activities are kauri wharf pilings. After the years of
logging, manuka and kanuka grew over most of the island but since 1955 the Forest Service
has removed unwanted trees to allow for the regrowth of natives.
Whaling, too, figured prominently in the island's early Pakeha history.
Because of its position along a migration route, whales were easily caught by motorised
catchers which operated from the Barrier until the nnd-1950s, concentrating on the
migrating pods of humpbacks and Bryde's whales. Being close to major migration routes has
also meant that the Barrier was a fairly common point for whale strandings. In fact, our
largest recorded whale stranding, that of 450 pilot whales, took place at Dawa Bay, on the
Barrier, in 1985.
Much closer to Auckland and a short ferry ride from the city is
Rangitoto. Formed by a volcanic eruption which started about 600 years ago, Rangitoto is
today covered with regenerating pohutukawa, together with mapou, mahoe, puriri and
kohekohe, along with over 40 species of fem. Also on Rangitoto are quite extensive stands
of rata, some of which have hybridised with the pohutukawa much to the fascination of
botanists. Possums and wallabies once occurred here in large numbers, inflicting great
damage on the vegetation, but have now been eradicated. The birdlife of the bush is not
very varied, consisting mainly of exotics together with a few native species such as grey
warblers and white-eyes, but there is an extensive colony of black-backed gulls, and blue
penguins as well as some shags also nest along the shore.
The jewel of the islands, in conservation terms, is undoubtedly Little
Barrier. Called Hauturu by the Maori, it was occupied at the time of Pakeha settlement by
a few members of the Ngatiwai people. After the island was gazetted by the government as a
sanctuary, the few Maori still living on Hauturu were evicted in what can only be
described as a very shabby manner. Here alone, however, the stitchbird survived, despite
strenuous efforts by introduced cats and bird collectors such as Andreas Reischek to
exterminate it. Reischek visited the island in 1882 and collected some 150 stitchbirds
knowing that they had already disappeared from the mainland. Cooks petrels and black
petrels also breed here, but their numbers were severely depleted by feral cats and it is
only since these animals were finally exterminated in 1980 that the birds have been able
to make a comeback.
The removal of cats has also allowed a number of other birds to be
released on the island. The first of these liberations was that of the kokako in 1981, and
this was followed by kakapo in 1982 and saddleback in 1984. The saddleback and kokako have
both bred here and their prospects for long term survival look good. Unfortunately, this
is not so with the kakapo, which has never bred well since its introduction, and there are
discussions on moving these birds once again to an island which more closely meets their
requirements, although the options are severely limited.
With a regular boat service from Auckland, Waiheke Island is the most
easily reached of all the gulf islands and is now considered little more than a suburb of
Auckland. Of all the islands it is probably the least interesting for the naturalist. Once
covered in kauri forest, it is now mostly either in pasture or scrub and the only sizeable
patch of bush is a couple of minutes' walk behind the settlement at Onetangi.
