BLOG POST 38
We first went to Punanga Manu o Te Anau Bird Sanctuary , set on the shores of Lake Te Anau, 15 minute walk from the Fiordland National Park Visitor Centre.
The sanctuary is open from dawn to dusk and caters for guided tours. Entry was free for self-guided visitors, but a gold coin donation is appreciated.
The rare flightless takahe are the star attraction of the Bird Sanctuary and meeting these prehistoric-looking characters was a wonderful opportunity for us all.
The flightless takahe is a colorful green and blue bird with an impressive red beak and stout legs. Thought to be extinct until its rediscovery by Doctor Geoffrey Orbell in 1948, the recovery of the species now falls under DOC’s Takahe Recovery Program
We could see the birds held in aviaries which had either been injured and cannot survive in the wild, or they involved in captive rearing programs. The injured birds are rehabilitated and, if possible, released back into the wild when they are strong enough.
An added bonus for us was the variety of free-flying birds seen around the centre. Many are attracted by the food available from the native trees and shrubs that have been planted around the park.
Native pigeons, tui, silver eyes, grey warblers, starlings, tomtits, bell birds, pied and black fantails appeared from time to time, often feeding in the bush at the lake’s edge. Small groups of green finches and chaffinches also visit, while harriers and falcons make occasional appearances, attracted by other birds.
We then saw the kakapo (or night parrot ) one of New Zealand’s unique ‘treasures’, with just under 150 known surviving birds it is listed internationally as a critically endangered species.
Large, flightless and nocturnal, the kakapo is an eccentric parrot which can live for decades. With mottled, moss-green feathers, camouflage is the bird’s main form of defence.
After a small tea break, we then began our trip to the Te Anau Glowworm Caves . We boarded a catamaran across Lake Te Anau to where the caves are located
The lake covers an area of 344 km2 (133 sq mi), making it the second largest lake by surface area in New Zealand and the largest in the South Island.
The main body of the lake runs north-south, and is 65 km in length. Three large fiords form arms to the lake on its western flank ,North Fiord, Middle Fiord and South Fiord ,the only inland fiords that New Zealand has, the other 14 being on the coast.
The lake has a depth of 417 m, with the deepest part of the lake 226 metres below sea level.
Several rivers feed the lake, of which the most important is the Eglinton river
The lake was first discovered by European explorers Charles Naim and William Stephen in 1852.
According to Māori legend there was a cave filled with glowing light somewhere on the shores of the lake. In 1948 this supposedly mythical cave was rediscovered, complete with the lights of countless puratoke (glow-worms).
Te Ana-au means te: the, ana: cave, au: swirling, in reference to an underground torrent that ran through the cave.
We were blessed with warm sunshine and clear skies. The high speed cruise across Lake Te Anau provided us with opportunities to view the majestic snow-capped mountains.
It was a little difficult to hear some of the commentary whilst we were up top - the noise of the wind made it very indistinct and it was pretty chilly on top
The Te Anau caves are a culturally and ecologically important system of limestone caves
They were discovered in 1948 by Lawson Burrows, who found the upper entry after three years of searching, by following clues in old Maori legends.
It later became a major tourist attraction for the area
The unofficial name used by the national caving association is Aurora.
After a short walk down the wharf and a path, where we came across beech trees
we arrived at the cavern house housing the visitor center , where our large group was split into smaller groups of about 8 people, each with our own guide.
We then rotated between touring the glowworm cave and waiting in the visitor center. Inside the visitor center there were several information placards where we could read about glowworms (life cycle, biology, etc.) and the history of the caves.
There was a power point presentation about the life cycle There was also a small concessions stand (with free coffee and tea)
The glow worms are larvae of the fungus gnat and have a life cycle, eggs are laid by the adult fly
Larvae (maggots) hatch 3 weeks later.
A young larva is only a few millimetres long. Over six to nine months the larva grows steadily until it is about 3–4 centimetres long. It hangs loosely from a damp, sheltered surface, inside a horizontal tube made of very flexible silk and mucus. When mature the larva becomes a pupa.
In the pupal or cocoon stage the pupa hangs vertically from a thread for about two weeks until emerging as an adult fly.
The adult fly cannot feed and lives only a few days – enough time to mate, and for the female to lay about 100 eggs.
The glow-worm’s tail-light shines from an organ with a blue-green light from it.
Glow-worm lines vary greatly in number and length, depending on the size of the larva and where it is living. Forest-dwelling glow-worms hang lines that are only 1–2 centimetres long, because they could get tangled in a breeze. In the still air of caves, lines can reach up to half a metre.
We found this underground world astonishingly beautiful. The cave are 12,000 years old which by geological standards is still very young and they are still being carved out by the force of the river that flows through them.
The result is a twisting network of limestone passages filled with sculpted rock, whirlpools and a roaring underground waterfall.
Reasonable agility level is necessary as some bending is required due to low cave entrances and steps being involved
This tour is not suitable for wheelchair passengers
Photography is understandably not permitted as it would adversely affect the glow worms in their habitat. Talking isn’t permitted either for the same reason.
Our group was taken in by the guide,it was a short walk in the dark using only the guide’s torch for light but following well constructed access ways.
We could see a few glow worms on the way to the boat but the majority are seen on the boat ride itself which is taken in the pitch dark.
The guide led us along a path built with non-slip surfaces, steps/scaffolding, and railings, stopping at a few quieter spots to briefly talk about the cave and its geology, etc. We also walked by a very powerful cave waterfall that was pretty powerful in impact.
After about 10 minutes, we reached the end of dry land (and lighting) where there was a small boat anchored to a rope that extended into the darkness.
Getting into the boat took a lot of dexterity and balance Once our group had boarded (everyone facing outward), the guide directed the boat further into the cave by pulling it along the rope it was attached to.
At this point it became quieter and very dark, and we began to see glow worms all over the cave walls and ceilings like constellations in the night sky. The guide did a great job of angling and turning the boat so everyone could have a good look at the glow worms
Once the glowing trip was over, we got into the catamaran and returned to our hotel as we had a long day ahead
