are increasingly seen or heard.
Cicadas
(kihikihi), butterflies (pepe), damselflies (kihitara) and dragonflies
(kapokapowai) are common.
|
Look
out for the deep red rewarewa flowers, unusual because they grow
straight out of the branch!
Ngaio
flowers are white with purple dots and about 1 cm in diameter. Look
for them along the valley floor.
Rich
orange pigeonwood (porokaiwhiri) fruit hanging in large clusters.

Fledglings
are gradually seen and heard more and more.
At
night, especially between January and March, little spotted kiwi
(kiwi-pukupuku) can be heard calling in the valley.
Cicadas
(kihikihi), butterflies (pepe), damselflies (kihitara) and dragonflies
(kapokapowai) are still easily found.

Konini,
the purple fruit of the kotukutuku or fuchsia, are a favourite food
of many native birds and were also used by early settlers to make
jam.
Small
white kanuka flowers are visible. This tree was extensively used
in Maori medicine.
High
in the canopy northern rata flowers can be seen. Close up you would
see sprays of scarlet stamens growing from the tips of the branches.
Carex
flowers can be seen in the wetlands.

Fledglings
continue to be heard and if you look carefully enough you might
see skinks basking in the sun!
Common
skinks (Mokopapa) give birth to litters of about four young. Usually
in January or February. At only 25 mm in length they are very hard
to see.
|
The
reddish purple berries of the ngaio are ripening. The fruit has
a thin outer skin, a fleshy middle and a stony central part that
contains the seed. In warm summers this tree may flower a second
time before July.
|

|
Autumn sees... |
| Settled
weather. Cold southerlies followed by periods of long fine, warm and
windless days. Calms occur in the Cook Strait most frequently in autumn
and early winter. Fogs usually occur between May and November. |
Shorter days
- 11 hours from dawn to dusk.
The first
frosts and occasional snow on the Tararua Ranges.
The end of
daylight saving.

Adult
birds are moulting, as it is the end of the breeding season. At
this time they are usually quiet and shy, but feathers are often
found.
Small
birds, such as the silvereye (tauhou), feed on the fleshy part of
the karaka. Kereru eat the seeds whole!
Migratory
birds begin moving north, the shining cuckoo (pipiwharauroa) and
the long-tailed cuckoo (koekoea) to eastern Australia and Micronesia.
|
The
deep purple fruit of the tawa provides food for kereru at this time
of year.
Karaka
berries are clearly visible. Dark green ripening to orange, these
beautiful berries contain a highly poisonous seed.
Masses
of very small, purple mahoe fruit are seen growing directly on the
branches, of the female trees.

Female
tree weta are laying their eggs in April/May, when autumn rains
soften the soil. They take about two months to hatch.
|
The
flowers of the swamp maire look like a white version of a pohutukawa
flower. Swamp maire as the name suggests grows in the wet soil of
the Valley floor.
Ti
koura or cabbage tree fruit can be seen in high quantities. They
are small whitish berries containing a number of angular seeds.
Fungi
with wonderful names - inkcaps, puffballs, bracket, basket and earth
star - are visible in the dim, damp places of the valley.

Three
species of native cormorants or shags commonly roost in two specific
trees on the edge of the lower dam. Their numbers peak during April
and May. Early morning and late afternoon are the best times to
see them, as they fly in or out of the valley for the day.
The
shags feed mainly on fish caught in the harbour. Look for the little
shag and the little black shag. Both are called kawaupaka.
Kaka
males forage on hinau fruit which is too hard for females to crack
open after March.
|
Strawberry
dogwood, a favourite of the tui is fruiting. At times, ten or more
birds can be seen in a tree squabbling over the fruit!
Deciduous
native trees, such as, kowhai and kotukutuku, lose their leaves
with the first frosts.
The
first buds can be seen on the stems of kohekohe and vine rata are
flowering.

Winter sees... |
|
The
shortest day - 9 hours from dawn to dusk.
Typical
winter days - the average temperature is 8 degrees C. (Maximum mean
- 11.3 degrees C, minimum mean - 6 degrees C).
|
Windy, rainy,
cold days and southerly storms are common. Southerlies occur most frequently
between May and August.
Snowfalls
down to 450m are common in the Orongorongo, Akatarawa and Tararua Ranges
in June, July and August.

Whiteheads
(popokatea), become more vocal. During the winter they often gather
together in large flocks.

Supplejack
(kareao) fruit can be seen on the ground. They can also be seen
in the canopy when you look from a distance.
Hinau
fruit ripen. Hinau fruit are an important food for kaka, during
their moult, March to August.
Kohekohe
produces flowers and fruit at the same time. The flowers are small
and white with five waxy petals. The fruit is thick and leathery,
but as it dries it splits to reveal three or more scarlet covered
seeds.

Pre-breeding
season activities increase, especially for forest birds.
Brown
teal lay eggs in a bowl of grass under dense vegetation, usually
between June and October.
|
The
beautiful fleshy bell shaped flowers of the fuchsia (kotukutuku)
can be found on some of the tracks. They range in colour from green
to violet as they mature. Look for the thick sticky blue pollen
on the flowers you find.
Heavy
clusters of deep green fruit can be seen on the marble-leaved putaputaweta.

An
important source of nectar for tui and bellbirds (korimako) during
July and August are five finger (puahou) and kohekohe flowers.
Courtship
feeding beginning for some birds in preparation for the breeding
season.

When
the weather conditions are right, clouds of yellow pine pollen can
be seen wafting over the valley.

Spring sees... |

Unsettled
weather - spring deluges and gales. Northerlies occurring most frequently
between October and January.

Nesting
begins for many species of birds. They can become very secretive
as they look for a suitable site, start collecting material for
nests and lay their first eggs.
Shining
cuckoos return in late September and the first ducklings are often
seen.
Some
cicadas (kihikihi) spend several years underground as a nymph before
hatching. In the spring the cast-off skins of newly emerging nymphs
can be seen clinging to the trunks of trees.
Bumblebees
(pi rorohu) begin emerging from hibernation and begin looking for
suitable colony sites.
|
Almost
no trees bear fruit in the months from September to November.
Nectar
from trees, such as five-finger becomes a critical food for tui
and bellbirds (korimako).
Native
clematis can be seen flowering on the western slopes of the Valley.
It looks like patches of snow!
Bush
lawyer is a climbing plant and uses other plants as a ladder. Look
for its flowers as you walk along the Lake Road, or the Swamp Track.
In
favourable conditions clouds of pine pollen can still be seen.
Rangiora,
or 'bushman's friend' as it is often known, are flowering. Look for
bunches of tiny off-white flowers.

The
breeding season is well underway for most species.
Welcome
swallows (warou) can be seen feeding above the lakes.
The
shining cuckoo (pipiwharauroa), return in late September and October
to parasitise the nests of the grey warbler (riroriro). This means
they do not rear their own young but lay their eggs in the nest
of another bird.
The
long-tailed cuckoo (koekoea) returns in October to parasitise the
nests of the whitehead (popokatea).
|
Kowhai
are flowering. First the bright yellow flowers appear, then
the leaves follow after it has finished flowering.
Flax
grows best in damp places and at this time of year they can be seen
flowering. Look for tui, bellbirds (korimako) and silvereyes (tauhou)
feeding on the nectar.
Mahoe
produces male and female flowers on different trees. They can be
found in small bunches on the stems and below the leaves.

The
breeding season continues - early season chicks might be seen and
heard. Adults can be seen gathering food for their young, including
second clutch chicks still on the nest.
New
Zealand's largest winged insect, the pale green and cream puriri
moth (pepetuna) can occasionally be found.
New
Zealand scaup lay eggs in dense cover close to water, from late
October to December.
|
The
strong heady scent of native jasmine can be smelt all along the
valley floor and if you look very carefully green hooded orchids
can be seen flowering.
The
dark crimson flowers of the pohutukawa or New Zealand Christmas
tree begin to appear. It is said the earlier they flower the longer
summer will be.
Beautiful
clusters of pale cream hinau flowers are also visible.
